Christmas? Not with the way my PS is spending my money!!! Help!

[patrick66]

This past month has been a giant PITA with my '95 CCLB 4x4 PS auto. I recently had a NEW fuel pump and a used fuel bowl, along with new fuel filter, rubber fuel lines, O-rings and bowl drain installed. The truck has less than a hundred miles since this work. Whether it's related to my current problem is unknown, so here it goes...

Coming home from work, I made three stops over the eight miles I drove before the truck quit. Each time except the last stop, it started up just fine and drove great. The last stop was the car wash - no, I did NOT wash under the hood at all, only the exterior of the truck! Washed the truck, jumped in, and tried to start it...all it did was the starter was cranking the engine, gauges and lights as normal, but the little bastard won't start for nothing! Doesn't even act like it wants to start! I've checked every fuse under the hood and all are fine. Not sure how to check the four circuit breakers in the power distribution box, or if they can be.

No smells, no burning, no leaks. Don't have a code reader, so I have zero idea if any codes are present. The %^&^&$%-er will not friggin' start! This is my transportation, so if any of you guys have ANY ideas WTF is up with my truck, I'm all eyes and ears!

thanks...

I've got inputs that it could be an empty fuel bowl, or possibly a bad CPS. Off to check the fuel bowl and go from there...!

[atvrider93]

doesnt sound like a CPS. try and get a reader on there.

hows it run when it was running?

[CHUCK]

Any smoke from the exhaust while cranking it over? No Smoke= No fuel.

[patrick66]

Fuel bowl is full of fuel, gauges (including the tach) and dash lights are working normally like any other time I start it, and there is NO smoke coming from the tailpipe when I crank the engine.

It has been running great! No problems after the fuel system fix...until now.

cple posibilities.......
IPR valve,
IDM bad,
HPOP bad.
If possible, swap out the IDM with a known good one (friend) to eliminate it from the equasion. Without a good scan tool you cant check the duty cycle of the IPR, but go look and see if it fell apart. It has a thin tin nut that can back itself off and allow the solinoid part to fall off of the rod ( I had that problem cple months ago). HPOP, see if its full of oil...

[patrick66]

I checked the oil level in the hpop reservoir, and it was maybe a 1/4" below the bottom of the check hole, so I added maybe a half-pint to it. Tries to start the truck again without success...Next, I did shoot a VERY small shot of ether a few moments ago, and the truck, and it did NOT start then, either. It did pop back through the intake tube to the air cleaner (I had disconnected it) and sorta-kinda wanted to start, but there was still NO smoke from the tailpipe.

This thing is really pissing me off.

So, now what???

WTF, over?

[retmotor]

Why did we rule out the CPS?

[patrick66]

Because, every response I've had said that if the tach is working while the engine is being cranked, the CPS is good. So, is this wrong information??? I don't want to just toss $$$ at this thing to simply guess what's wrong and hope it works. I certainly can not afford to do that.

I'm renting a OBDII code scanner tomorrow and see WTF it says about this, then go from there. I don't know anyone locally with the same year range PS truck to swap parts to troubleshoot that way.
