99 PSD no start - no smoke - hair on fire
 

Hello: i cant get a big white, ugly pk-up out of my driveway and to the work site where i used to make money

it runs 1 day out of 30, (make that 1 / 60)
ran the other day for 20 miles, restarted hot
would not start the next day
it did that 2 weeks ago as well
otherwise it took the winter off

I have 2300 psi Injection Control pressure (can u still have show stooping HPO leaks ie Injectors, elsewhere?)
had a bad connection to ICP now fixed
have changed IPR
new CPS
3.29 - 3.15 Fuel Pulse Width
32% IPR Duty
45 - 60 psi fuel pressure after bowl
140 - 165 rpm
have WTS
have tach inside

changed PCM
examined connector, looks OK

tried a second (used) DCM
with fuel pulse width at 3.29 it is working ... no?
wires over Valve cover are OK



Correct oil level, changed oil, LPOS pumping / oil res full
Correct type of fuel
Correct fuel pressure (50+ PSI per Ford spec)
Sufficient air supply
Proper oil level in HPOP reservoir (1 to ¾ inch from top)
Glow plug relay works and glow plug operation is BAD but 80 here today and NO smoke

drained filter housing and cleaned
verified fuel is filling filter housing

had (newer) batteries tested and charged / cleaned posts

any ideas?

Thanks for your time

So you've tried a different idm? Have you checked that the engine harness hasn't rubbed through a wire where it lays on the driver side valve cover? Being able to check for codes would help a lot. Have you checked the valve cover harness and connector both outside and under the valve cover? Have you checked for oil squirting out of the injector vents while cranking?

Yes and no. the wiring across the DS valve cover appears fine, there is 1/2 " spacing above the VC.

I have not had the VC off. Which speaks to my short understanding on this restart. I would not know what i was looking at. If u have 2300 psi in the HPOS can u have show stopping leaks in the system? If one injector was leaking would not the others try to fire. Why would it work one day and not the next. Would a bad UVCH be on and off problem?

what / which is an injector spout anyway? Thanks

sometimes the connector on the inside can work its way loose and be intermittent for a while and then eventually loose connection. Check outside connector terminals and inside connector and make sure its secure. I wouldn't think you have a leak on the high press. oil side if showing that much press. The spouts look like little turn down tips that bolt to the injector with an allen head bolt. If you have oil coming out of it while cranking the injector is working. Can you hear the injectors clicking while cranking?

I got the Driver Side VC off, there should be a warning about the bolt against the firewall.

anyway, the wiring appears (to me) to be OK

the injectors are NOT firing

tried the old idm, no luck ... they could both be bad

thanks

Have you tried plugging the block heater in? My friends 99 7.3 would not start because of a bad glow-plug relay, there for when he would plug it in, it would start no problem.

well i'll be able to put 4 GPs in now.

but what on earth is keeping the injectors from firing?

what can i do to narrow this down? Thanks

IDM, wiring, fuses/relays, cam sensor. If you could get a hold of a code reader or scan tool it would help you alot

IDM :could be bad , i have tried two, can failure be intermitent or better can it be tested?
How can you test power to IDM and is that a relayed cycle ignited by PCM

WIRING, Looks OK but connection to IC Sensor was bad. I have a good 98 eng harness,
(this is a 99) ill see if it 'fits', I know it is modestly different with regard to turbo
sensors and altirnator / perhaps I can cut and paste a good harness together for
a test

FUSES and RELAYS keep testing OK
Fuses/ the PCM, switch and dash gauges, CPS are 'lit' / is there a fuse specific to IDM?
Relays, anything other than GP? anything in the fire cycle for injectors that is not
clustered with PCM / Dash Gauges / CPS that is powered now?

Is there anything key switch related (direct to IDM perhaps) in the fire cycle

CPS cam sensor. changed twice / reset 4 times

Thanks

Checked / reworked battery Wires and clean grounds to block / took BATS to store for check and full charge, one like new one only slightly off

No codes thrown / checked fro codes with two different PCMs

2300 psi HPOS / IPR at 32%

12.2 volts no crank ... with 10.5 / 10.6 when cranked

55 psi fuel after bowl

165 rpm under crank //// CPM is working (?)

3.5 pulse width /// doesn’t that indicate IDM working?

I have a 99 AA IDM ....... tried a friend’s 99 AB, nothing //// would not a BAD IDM throw a code?

Cover off / wiring appears OK / injectors not firing

New oil / oil in reservoir

Truck ran 20 miles 2 days ago and for 20 miles 2 weeks ago / otherwise no start over 3 months

thanks

have you buzz tested the injectors? or atleast check the armature clearance?

Not sure if this silly Auto-Zone reader can do a Buz test. Ill try it out.

I was really expecting to see at least some codes. I think ill disconnect something to see if I get a code. that just seams so odd

The truck ran the other day. It ran well. For all 8 inj to go so far out of spec that none fire over-night seems out of bounds, Am I wrong on that? Something is intermittently stopping the signal to the injectors.

---AutoMerged DoublePost---

With regard to the IDM , do they have to be a exact match AA or AB ?
The back-up I have been trying is an AB whereas the truck original is a AA?
Has anyone experience a 'ghost' intermittent IDM failure. Work for a couple hours ... not work for a month .....work for a day then quit for a few weeks?

I am looking for a trial available AA right now / see if I can make that happen

Thanks Again

any 7.3 IDM will work. and a autozone scanner will always show a pass 1111 code since it does not have enhanced capabilities of ford diesels. and yes the injectors can get bad that fast especially with rotella oil. if it were a glow plug issue it would atleast smoke out of the tailpipe when cranking. try plugging in the block heater and see if it starts, warming the injectors with the block heater may make them grow enough to start

Perhaps BOTH IDMs that I have have failed, the one intermittently, but I am getting a Injector Pulse Width of 3 Mil-sec which I thought was an output function of the IDM

Can you walk me through the the non-code issue .... have you experienced a No Code result before ie no pass 1111 code result .... I mean what the hey ... no codes found?? (?)

Thanks

---AutoMerged DoublePost---

Sorry I was going to add that with regard to GPs, the Injectors are NOT firing , you cna see that they are not, As far as I know there is no feed back loop with regard to GP function. If all GP failed it would still fire the injectors -- perhaps not start ---but fire and smoke. Is that not true. ?

Same with injector clearance, as far as I know, again no feed back to stop injectors from firing because of clearance issue. Am I wrong. ?

Thanks

the pcm sends mass fuel desired to the idm and it does the rest. generally a failed idm has a code such as p1298 and injector codes such as p1316. you just need a better scan tool for the diag such as auto enginuity

Waiting for a tech with a better reader ... perhaps tomorrow. Ordering a different (3rd) IDM just to experiment

Found new clean oil in the valley can not replicate a leak under crank. No visable leak. Casper has not run, has not fired, with the 'new oil' in place .... perhaps it was spilled during refill but perhaps a clue. Again I am reading 2300 psi but injectors do not fire.

If you get 2300 psi HPOS via ICP to PCM I would think that closes that loop. But can air in the HPOS or any other HPOS leak type circumstance interrupt signal to PCM, or trigger any other deal killer circumstance with read to non-fire??


On the block, drivers side, not far from ICP but on the otherside of the forward lifting eye, is a heavy wire , looks like a ground wire, is anyone familiar with what that is and where it goes?


thanks for you time

bad cps or wiring could do this, or injectors,ect. along with dozens of other problems could cause it!

Preakness Special
 

Since it is Preakness Day: I have two ready-to-cook Baltimore Crab Cakes (+FEDX) for anybody that can get 'Casper' Going. Right now it is Stop-and-Start with a high degree of Stop

It is not the CPS and I have tired 'dozens of things'
WTS works / dash tach works
Replaced the OEM CPS twice, redid wiring and re-positioned 2 more times

Checked all fuses and relays/ re-positioned all

Checked / reworked battery Wires and clean grounds to block / took BATS to store for check and full charge ,12.2 volts no crank ... with 10.5 / 10.6 when cranked, 160 rpm @ crank

No codes thrown / checked for codes with two different PCMs

Checked all known connections

New oil / oil in reservoir/ oil pressure under crank/ 2300 psi HPOS reading from ICP / IPR at 32% / new IPR / ICP wire and connection replaced

55 psi fuel after bowl

3.17 - 3.5 pulse width

replaced IDM twice Mine was AA but ford said AC should work ... (don't know (?)

Cover off / wiring appears OK /over valve cover / replace any remotely suspect wires in engine harness / injectors not firing

Local independent says it is a HPOS leak and it will start cold. The truth is it will start when it wants to / and has nothing to do with cold.

Truck ran and started 20 miles 2 weeks ago (hot and cold) and for 20 miles 3 weeks ago / otherwise no start over 4 months

(there is one heavy undone wire I don't know what it is. Close to the ICP but on the other side of engine lift mount)

Is there any other function key switch related that can kill the motor. I have power to PCM, GP, CPS, and starter

thanks

where are you located? i'm not a seafood person but I might be able to help if you are ready to dig in deep
click diagnostic guides button, then print diesel engine diag. guide for your appropriate year. fill it out with precise info and we can go from there.
POWER-STRUCK, osgood indiana, performance tuning

hey I was reading your post and was wondering if a super chips tuner would read the codes you need to read I have one that came with my truck when I bought it and I basically never used it as I went w a dp chip. id be willing to send it to you if you wanted to borrow it if you have a ups acct number..

PowerStruck: I am on it, ill try to follow it, but again no one around here seems to be able to do the reading correctly ala the language of powerstroke

Bestrada11: that is a very gracious offer, the 'chip' thing is above my pay grade but I am trying to see what the super chip can read. Ill try to get a UPS acct # ASAP

I am near Erie Pa right now. Spent 30 yrs in Baltimore and due to an admitted addiction problem, have the crab jts number above my desk.

Don't like Seafood .... name your poison. We get as few as 55 days of sun here and Casper has used up 3 this wk / it is getting personal

Yea man for sure I can also look at the model number so u can clear up what it might read. All I know is it will pull codes

really need auto enginuity or some sort of tester that can do on demand tests along with pid datalogging

Bestrada11

Superchips says it will read codes / as well as other readers / I dont know
I would like to try
I have a UPS account / please contact me at mbarnes.cm@gmail.com or

thnx

bestrada11

How do I contact you?

thnx

barnes @ mrjunks

THNX to the heroics of bestrada11 I got a reading today of:

PO340 � CMP Camshaft position sensor ckt. malfunction ----- Open/grounded circuit, sensor fault, short to power

(CMP changes 4 x, wire replaced in harness / I am getting RPM (160) to reader and gauge inside)

P0603 � PCED Internal control module KAM error ---- Open PCM pin, disconnected B+, faulty PCM

P0472 b EBP Exhaust back pressure sensor circuit low input ----- Open/grounded circuit, biased sensor, PCM

P1210 b ICP ICP above expected level ---- ICP sensor, open signal return

Any ideas on where to start

thnx

prolly a 3 wire sensor shorted to Vref

'a 3 wire sensor shorted to ' (Vref)

come again

a three wire shorted to ground??

thnx

---AutoMerged DoublePost---

Can anybody define what was meant by Vref
was that a Typo?
Or something I should be moving on?

thnx

I take it Vref might be voltage reference

Does anybody know what that might indicate / a short in a plug? A short in the wire harness, ??

Thnx

Have the same problem and throwing a p1316 and p1670 codes

---AutoMerged DoublePost---

Any answers?

If your cranking on it is there at least unspent fuel coming out of the tailpipe? If not I would say your having issues with your glowplugs or GPR I had to replace mine last winter. It would only start after being plugged in for awhile but even at 30 40 degrees it wouldnt start after sitting over night. I've worked in the IT industry for 20 years and one thing I always do is start with simple things first and work your way though a system.

Back to work on F350
 

Returned from west coast project, back still trying to start F350 /7.3

I have a reader and bunch of codes

1280 ICP to low
1210 ICP to high

198 Oil temp high (eng cold)
1119 Air temp high (eng cold)

1690 waste gate failure (intake plastic manifold off)
475 exhaust pressure failure

340 Camshaft position sensor ckt. malfunction / Open/grounded circuit, sensor fault, short to power

but I have rpm reading via port plus tach reading
(changed CPS 4 times / ford parts, rewired to top of engine in harness)

640 manifold Intake heater

anybody familiar with these codes / have input

thanks for your time
