Still won't start
 
I have a 02 24v 5spd and I recently encountered a list of problems all at once and I put a new vp 17x pump in it and a fass 90gph lp in it and even went as far as reseting the time to factory and when I pulled the injector I had fuel in the cyl and the truck acts like it wants to fire but just can't and someone had said that it maybe a injector bleeding pressure.. So here it goes the truck has 300k on it and original injectors is it possible for all 6 to go at the same time or should I start with one and go down the line and also is it possible for one injector to cause it not to hit and I have 16psi with ignition on and I also cracked the blessed on the filter and it is flowing very good so any info would be very very very helpful thanks in advance:argh::scare2:

What is a "vp 17x" pump?

You "reset the time to factory" how?

navy_welder 11-18-2010 01:19 PM

A bosh vp44 Ho injection pump witch is a 17x when it is remand and factory time is the from gear timing marks per the dodge dealer

---AutoMerged DoublePost---

The whole number on the pump is ipvr17x bosh injection pump

---AutoMerged DoublePost---

Oh and on the compression stroke wit both rockers under no pressure moving freely and lined up the o o on the gear assembly witch is timing marks

Just got thinking about he fuel in the cylinder. Unless you drained the leak off line in the head, it will all pour into the cylinder when the injector is removed. I can't believe I didn't think of that.:argh:

navy_welder 11-18-2010 05:45 PM

I pulled the line and injector tube before I pulled the injector cause the injector won't come out without pulling the tube first

---AutoMerged DoublePost---

Oh and all tubes have new o-rings as well

mysterync 11-19-2010 06:16 PM

Well first of all, You cant set the timing, It's keyed. So I'm guessing you "reset" the cam timing which I could hardly see useful, Considering We dont even pull the front cover. Even pulling the connector tube first you will fill the cylinder with fuel. SERIOUSLY doubt its an injector problem. I'm guessing you bled the injector lines? And I'm guessing you verified the O-rings on the connector tubes were good. With all that eliminated I would be looking at a bad ECM or PCM or Pump. Just because it's a new pump does not mean it's a good part.

KATOOM 11-23-2010 02:19 PM

Have you checked your fuel systems fuses and relays? Are you even sure the VP is getting power? Did you make sure the VP connector plug is fully engaged? And as already stated, the VP may be no good. The chances of the injectors failing are slim, especially all of them. If the VP's getting fuel and the VP has power then the chances of it starting are very good. Doesn't mean it will run great if there's other issues either.

navy_welder 11-23-2010 03:12 PM

Well for one I did pull the front cover as stated and no I didn't just reset the cam timing I reset the whole thing and thank you for basically saying I'm incompitent I have ran into just about every problem you could think of and also mr rawilliams already stated that it couldn't be the injectors and also if you would read closer bud the injectors aren't designed to last as long as the ones in my truck have 300k miles and for that fact I also stated in the first post on this subject that I made I stated I went through and replaced all injector tube o-rings and injector o-rings due to the fact that I am a heavy equip mechanic and ruled them out a while ago then the ip pump is good and has power as stated as well and yes the connector is fully fastened and also in another post on here also stated that the chances of the pump being bad from the factory is slim to none and the symptoms I described could mean 2 different things and because I ruled one out the only other thing that would keep it from running is the ECM considering the way it derated the engine instead of it just dyeing

crzycummins 11-23-2010 04:05 PM

easy big fella...were just trying to help. have you tried a new computer yet?

RAW 11-23-2010 04:16 PM

I believe he is trying to track one down to try out.

navy_welder 11-23-2010 07:21 PM

I found one I just don't want to spend 300 on a Ho ECM and it not work and sorry bout earlier had a frustrating day


Any one got one just sitting around

---AutoMerged DoublePost---

I mean if someone has one they are willing to offer up for the experimentation I would be more than willing lol but if so pm me or something

Red_Rattler 11-23-2010 07:35 PM

I still think i have an ecm outa my 2000 non ho though

mishkaya 11-23-2010 07:37 PM

I don't want to insult your intelligence, but when you crank the engine, does the tach move? It's possible the cam position sensor got disconnected when the VP44 was replaced. If it's not working the VP44 will not function. As stated earlier, you might want to check your fuel relay (you can swap it with the horn relay). Also check the wiring connection at the VP44. If all else fails, you can hot wire the VP44 to eliminate that as a possibility of failure. For that you need to run power to the #7 pin and ground the #6 pin; that will run the VP44 independently of the ECM. If the truck starts, you will know that the problem is elsewhere. If it doesn't, it could be injectors, or the fuel pump...

Farmboy 2.0 11-23-2010 07:46 PM

Ok maybe a dumb question but are the injectors seated properly? Connecting tubes not seated properly? Have you cracked an injection line at the head to see if there fuel and the connecting tubes?

navy_welder 11-23-2010 07:50 PM

I know the cs is plugged in cause I went over everything on the harness and I could do that

---AutoMerged DoublePost---

And thank you for the offer on the 00 ECM but that one requires a crank and cam sensor instead of the cs only but I do appreciate it:choochoo:But for future reference it has to be a 01 or 02 manual ECM

crzycummins 11-23-2010 08:14 PM

:humm:

navy_welder 11-23-2010 09:06 PM

Oh and I put a new relay in the truck on the fuel system and also I have a fass platinum 95

---AutoMerged DoublePost---

And the wires on what connector the ip connector or the ECM connector and to make it easier what color are the wires

You need to hot wire the VP44 directly. I cannot recall the colors of the wires going in, but it doesn't matter as the connector shows the pin numbers right on the harness side.

navy_welder 11-24-2010 09:36 AM

Ok will do but it won't be for a ew days I am officially on a liquid diet for the rest of the week haha

---AutoMerged DoublePost---

:jump::tttt::rocking: with plenty of music I think I'm already bout to get the cops called on me haha

mainman300 11-24-2010 11:40 PM
