OK, all fixed. For the archives I replaced the IP with another and she fired right up. All is good. Lessons learned: -Even though the IP was rebuilt by a reputable company and it was "thoroughly bench tested" it still had major problems. At least the company did right and provided another...

Yes, the IP was full of fuel and I did hear the clicks of the fuel and cold advance solenoids. Also, I swapped the check valve with other IP cores I have laying around. I even tried running with no IP check valve and dumping into a bottle. Nothing helped. The new IP is due in tomorrow. Might...

Thanks for the suggestions Ted. I did blow into the return line at the IP ( I know diesel is not tasty) and I hear the bubbles in the fuel tank so I think it is clear. The batteries are new and the engine cranks fast until I run the run the batteries down trying to start. I do recharge them...

It is an engine from a donor vehicle and I never got it to start with the old leaking IP, but I determined the PCB was bad and had no operational glowplugs at that time. I replaced both the IP and glowplug controller at the same time. The glowplugs are working fine now. We'll see what happens...

Thanks for the info. I'm the one who installed the IP ( the old one developed a huge leak). I did install with the pin in the oval hole ( and verified yesterday). My glowplugs do heat ( actually pulled one right after cycling and it smoked when I touched it to my glove). I then unplugged...

Another update: I talked to the IP repair house and they said the flow rate through the IP and out of the return port is set by them. The lowish flow is normal. They use 5psi fuel pressure when setting it up and the 8psi I am seeing should be fine. They suggested advancing timing by 1/8" which I...

Yeah. Just seems odd. Anyway, another update. The bubbles seem to be clearing up and I now installed a pressure gauge on the top of the fuel filter canister. I'm getting 8 PSI of fuel pressure at the canister ( which is high since the TM says 3 PSI) but still low flow through the IP. When I...

Hey all, I've installed a donor 6.2 into my HMMWV and I'm having one heck of a hard time getting it to start. The wait to start light comes on for the right amount of time. It will crank for several minutes ( 20 secs at a time) with not so much of a kick. Then it may slowly fire a cyl or two ...
