Greetings all!

I have a '94 K2500 Chevy, 260K miles.

Parked in driveway, next morning no start.

Lift pump replaced.

Fuel is to IP.

IP replaced at 150k mi.

No fuel to injector lines, verified by cracking line and cranking engine.

OHM'd, then removed solenoid valve (?) from IP.

Solenoid valve appears to function normally with key switch position.

Fuel spills from IP with solenoid valve removed, during cranking.

With fuel to the IP, but none to the injectors, has the IP failed and need to be replaced?

Thanks in advance,

Welcome!!!

I know you have worked hard to post this.

Would you mind going a step further to DO the diagnostic checklist on the sticky?

That way, we can help you eliminate some cheap things before throwing parts at it especially something like an IP.

Here (http://www.dieselplace.com/forum/showthread.php?t=42248) is a link to the diagnostic checklist. It is alot of work but, if you run thru it properly it will help us and you diagnose the problem(s) you are having with your truck.

You will be steps closer to driving your truck down the road again after runing the checklist and posting your results here.

Wish you luck!

The other nice thing about TheCheckList is that sometimes (every time for me) you can solve the problem on your own when you get to a checklist item.
For me it was the fuel tank cap - Had vacuum, removed the cap, ran great, got a diesel cap, still running fine.
This is one super troubleshooting guide! Hopefully your's is something as simple.

I have a 97 so what Bill told me may or may not work on a 94.

I replaced my pump and it is running great. I did not want to do it till I felt I know that it was the pump because a pump is many $$$$.

Sounds like PMD issue since you have no fuel at the Injector lines.

LP is new, is the OPS good? OPS will run the LP after it is cranked. Eliminate this first before replacing PMD.

Search on PMD in this forum.

just a side note...is it a C or a K 2500 because it can NOT be a CK as C = 2WD and K = 4WD so unless it's got a T-Case that self removes on command...its one or the other...may not be of any use in this particular case but on future threads you may post...saying its a c and then asking about the front diff may confuse people if it IS in fact a K or asking about a tranny swap will get confused if it is a C not a K as people will be telling you to remove 2 driveshafts and a t-case which you won't have, and i did notice in the first post you say K but you then say CK in the checklist...just cheking if it's a typo or you just honestly don't know. no big deal...i had a hard time figuring out R/V1500 on my gmc burb

Truck model is K2500.

Is the CPS test valid for a '94 with this problem?

Can the PMD be checked as described by Carey?

Thanks in advance,

Generally, PMD cannot be checked. The only way to check is to use a known good PMD and replace them.

Since you may be replacing the PMD, it is suggested to put it outside the engine compartment on a heatsink to ensure reliability and longevity of PMD/FSD.

Hi folks and thank you for your pooled wisdom. I need help.

Running Biodiesel from WVO - no problems for about 7K.
Truck started stalling and restarting, starving for fuel and wrestled with problem for a while. With trouble codes indicating: IP metering control; crankshaft pos sensor; others. After ruling out about everything including the PMD/FSD, I opted to replace the IP. Truck ran good for a couple of thousand miles after IP replacement.

Fuel delivery problems seemed to cause new troubles. Found air leak in supply line and repaired. I have complete access to tank as truck is a pickup dump. Sock in tank replaced.

After fuel fillup, truck stalled after a mile. I suspect bad fuel. Fuel is filtered down to 2 microns and no chance of water, but too much of coincidence. Truck would not start. After several hours setting, it did start and ran irrattically for the 1 mile home stalling on hill (no power) and restarted and got home to stall in driveway. Truck never started again.
Lift pump seemed to be bad as it was not pumping and replaced and fuel supply is a geyser at the filter. Last codes revealed: manufacturer computer & input from sensors; crankshaft pos sensor. CPS replaced and PMD/FSD checked from pull from running truck. ECM computer swapped from running truck. Fuel is available up to the IP, but nothing at the injectors. I cracked 3 lines and then took them completely loose and no fuel is coming out at the injectors with extended crank. I checked every possible electrical connection, even at the ECM, under dash, hood, at firewall, grounds, etc. Totally baffled. Can bad fuel cause new IP failure?

ANy help much appreciated.

May I suggest to create your own thread!!!

I will look into the creation of a new thread.

Does anyone know about the test with the voltmeter on the terminals of the PMD. I am getting .002V- nothing on 'A'

What does this mean? ECM? I checked it with the plug unplugged and plugged in with just a little insulation shaved off so the probe could get a reading.

AN interesting problem occurred when I put back the canalized runner (I took the ECM and the PMD to test the broken truck). The runner is a no start and the same test with the voltmeter was .001 - .002V. It is supposed to be 1.2V with the key on they say. Any ideas?

I think I was supposed to crank the engine for a reading.
