1999 Powerstroke Problems
 

Hey guy, i have a question about my powerstroke. ok so my alternator went bad and started to drain my battery, replaced it, about 2 months later my truck starts to have problems starting when it got cold and it dies when i turn my windshield wipers on. And someday it runs fine and some days it runs lopey and crap like. Any ideas whats wrong with her?:argh:

When its warm it runs good? Only the wipers shut it down?

yea i runs like crap the whole day even after warming up. And then the next day she runs fine. Yea only the wipers kill it. It like dies for a second then it goes again no problem.

i got a 1999 and when i start my truck sometimes it will blow white smoke and sometimes it wont and the water in fuel light comes on every now and then and just redid injector sleves anyone know what could cause this:argh:

I would like to know about the wiper thing too. The 02 my boss drives has the same problem sometimes. With the wipers on it acts like you turned the key off for a second and then runs just fine for a while. It happens at random times.

is it raining out when when this happens? have you ever re-sealed any doors or cowls or the windshield? has anyone ever had the steering column apart?

does it seem to run crappy on cold days or warm? or both?

how many miles on the truck? any mods? aftermarket fog lights or spot lights? or has anyone ever done some wire hacking under the dash?

also what are your maintenance habits? fuel filters, oil, etc...

The truck is dead stock, about 150k miles but I had to put a used engine in it for him last year because the previous owner had run it with a bad injector in #8 until it had low compression there. Then the HPOP went out and it was cheaper to get a complete used engine than do all the work on the one that was in it. The engine I put in came out of an e99 so I had to change a lot of outside parts from the old engine to make it work. The only time he runs the wipers is when it rains but it doesn't seem to matter if it a cold rainy day or a hot summer rain. Nothing has been resealed since he got it but I can't say what was done by the previous owner. There are no leaks into the cab. It is dry inside even in the hardest rain so it shouldn't be an issue with the fuse panel. No aftermarket stuff on it. I don't see any signs that the harness has ever been disturbed. The maintenance could be improved on. The oil and filters have not been changed as often as they should. The fuel filter was changed about 3 months ago. It is almost impossible to start cold unless the block heater is plugged in but when I did a buzz test only 2 or 3 are buzzing right so it needs injectors. It runs OK after it starts and warms up a little.

has the multi-function switch ever been messed with (left/right signal, wipers, high/low beam switch)? if im not mistaken, im pretty sure a major power wire runs through that switch to your ignition

It sounds to me like a short with the windshield wipers and bad injectors?

thats why im thinking this multifunction switch is having an issue, im pretty sure an ignition wire runs through it :humm:

and yea get a new set of injectors, sure it could use glow plugs too :rocking:

update since its been cold out it dies at random times at every minute sometimes. thinking about it if dies without wipers, yes it does die accually sometimes. All Stock No mods 225000 miles. only get 14 mpg if that helps. glowplugs are fine. Have to wait whole glow plug time even warmed up or wont start. had cps sensor replaced twice. had new injection computer as well.:argh::argh::argh::argh::argh::argh:

14mpg isnt really abnormal, you'll hear guys saying they get 18-20+ mpg with their STOCK truck, they're blowing smoke up your @$$ :td:

I'm thinking a possibility of a weak oil system now :humm:. Has the truck ever had a set of injectors? High pressure oil pump? ICP sensor or IPR?

Guys lie about 2 things>>> Fuel mpg's and..........:w2:

fuel mpg and... fuel mpg and..... smoking the reefer? haha HORSEPOWER

i'm honest. i get about 16- 17 in town and 12- 13 @ 80 MPH, pretty bad :td:

Jeeze I'll agree with you there, but fortunately mine does the opposite haha. I'm getting anywhere from 14-17 around town to 17-21 highway :choochoo: (21 was achieved on I80 East in Ohio with a good tailwind on stock tires with the cruise on 70, and everything in my sig:tttt:)

My 94, I got 20 running 90 with a 45 MPH tail wind. Exhaust, intake, and super chip. But my dually sucks. I wanna try doing 75 and see what that gets me. Then empty trailer and then loaded.

i found after 60-65mph it starts dropping off the other way :argh:

I get better fuel mileage when running tranny fluid as fuel. But i still get about 17 in town on regular fuel. Not bad for an 8k pound vehicle. But as far as cold starting with a 7.3 its normally either glow plug relay or service related like oil changes or fuel filter. But if the buzz test isn't passing then that should be addressed first.

I'm sure it loves that :s:

before this turns into a fuel mpg thread like the 20 others on here......

He stated that the glow plugs and relay tested fine. Only 2-3 injectors are buzzing, with 225k on the truck it's WELL overdue for a set anyway. Life expectancy is only about 150k, a little more if you do regular maintenance.

I'm also thinking voltage changes in the system (turning the wipers on) is enough to bug a possibly failing IDM :humm: Or that multifunction switch in the steering column has something to do with it...

Ok guys i need answers now yeasterday it cuts out so often now and dies going down the highway it idles so fucking bad just a low grumble and when i hold the pedal in a constant spot it will reve up on its own and slow down on its own. I wish you could tell me whats wrong. Im afraid something is going to break because of the way it jerks on the highway i mean its just Boom like the breaks get slamed on.:ouch::argh::argh::argh::argh::dang::dang: help now if you can tell me what it is

has the HPOP ever been replaced? I said a couple posts ago that this kinda sounds like a weak oil system or a possibly failing IDM or IPR. Can you get a scanner on it?

---AutoMerged DoublePost---

it would really help if we could see what your IPR % is with key on engine off, at idle, and going down the highway when it's doing it. I would also like to see what your fuel pressure is, along with your ICP (injection control pressure).

Has the IDM ever been messed with or opened to check for moisture?

---AutoMerged DoublePost---

when the truck starts to bog and slow down "like the brakes get slammed on", do you hear a whooshing noise from the exhaust or under the floor? And has the EBP sensor (exhaust back pressure) ever been replaced?

its doesnt bog down it dies like 3 times in a row. also i just realized this but ya kno how powerstrokes idle high well they are cold well it does that when its warm. i mean it will set and idle but then kick up and idle high like it thinks its cold.:td::nope:

well what's the temp outside? 7.3's are a cold bitch, if they sit and idle long enough for coolant temp to drop below a certain point (i dont know what the limit is), they'll kick up in high idle to get back up to temp, my fathers excursion will do the same thing even after running for 4 HOURS.

any info on anything with the high pressure oil system? Or codes?

Have you checked for fuel airation? Doesnt happen very often with the newer 7.3 but had a tendency with the old ones. Its possible. But it does sound more like an oil issue with the h/p side, maybe ohm out the injectors at the harness?

ok another update well i took it to my local diesel shop and they replaced the oil pressure sensor or something and that fixed the idle problems. and idling and dieing frequently.:tu: but it still dies when i turn the wipers on delay. My diesel shop ordered me a new wiper motor do i need it?

Oil pressure? That's what your ICP sensor is (Injection Control Pressure). Find out exactly what they replaced :humm:

Well, your wiper motor does use quite a bit of amperage. Unless it has an internal short (which should pop a fuse) or its drawing an INSANE amount of current (which should still pop a main fuse), and the motor is working fine, i DO NOT think it's a motor. I think it's more likely something to do with the multifunction switch that controls your wipers and signals. Those cause a bunch of wacky issues.:s:

---AutoMerged DoublePost---

can you give me what options the truck has (power locks, windows, etc...)? I'm going to look up a wiring schematic and dig a little bit

From what I'm seeing, there's a run/park relay for the wiper motor inside the multifunction switch that is hot in accessory or run.

power lock power windows uhhh its an XLT that should tell you everything.

---AutoMerged DoublePost---

also with the multifunction switch what do i need to do with it like have it tested or replaced and yes it was the ICP.

well i'm not sure how you can test them. other than put it in another pickup.

I removed a command start from 02 and now it seems like its not gettn fuel and the glow plug relay isn't workn,is there a link be tween fuel shutoff ansd the glow plug relay

what??

:s:

---AutoMerged DoublePost---

well, those switches are hard to test, just simply because there's a lot of wires. your easiest bet is to just replace it, they're not that expensive. (or hell just go to a junkyard and nab one off a totalled truck or something :tu:) they're easy to change:rocking:

1. disconnect negative battery cables.
2. turn key to "run" position
3. locate small hole under the ignition lock cylinder in the steering column, insert a small punch (or small allen key) and give a little push. (this pushes the lock cylinder detent back into the lock cylinder)
4. pull outwards on lock cylinder (ignition switch).
5. remove plastic covers around steering column.
6. viola! :jump: full access to whatever holds it in.

it's 2- T20 or T25 torx screws. and 2 small plugs :tu:

If the wiper motor doesnt do it, I'm pretty confident it's something in that multifunction switch. Like i said earlier, they cause all kinds of wacky $hit:argh:

when that switch went out on my moms 97, the only thing it caused was no turn signals. but it still took me a while to figure out why i didn't have turn signals.

HEY guys! dan my man i replaced my mult function switch. No luck. :dang: SO anymore suggestions i mean shes been doing real well. pulls like a dream. but stil dies when i put wipers on DELAY key word is delay. she dosent die then i put them on full go. only when delay. so if that help hit me back! :tu:
