i have searched and got a lot of different things but I can crank it, a whiff of ether causes a light start, i have 2300 plus psi of ICP in my scan tool but i cant see fuel pressure on it, i checked at shrader and it slowly moves and will get as high as 30 on extended cranking, but it surges its way up like it goes squirt... squirt... squirt. i pulled the line to the head off it has flow but doesnt seem like a lot of pressureit was running and died on the road, all it had was cam sensor issue (code), i found a questionable harness at that sensor and replaced (one wire at a time) and the sensor for good measure i am thinking fuel pump under the turbo, or IPR?
going through flow chart i do see over 20psi on lots of cranking, i have checked icp and tried to start with it unplugged, icp pressure is 2300psi, tried another idm from running truck, changed cps and checked wiring,
ok finally back on this POS van, my OTC will let me fire injectors and it does 1 at a time then fires all 8. I initiate test and... nothing, so I try again and use a multi meter and zero volts, should be 115v I'm thinking IDM. I did try one from a running 97 pad truck. the local diesel place said I can use a newer IDM in an older (95) truck/ van. can anyone confirm?
I don't think you can count on a digital meter to check injector voltage. Since it's a fast pulse, the digital meter won't respond quickly enough. You need a 100-ish V noid light; I think some fellas have fabricated one.
well would they not be either power or ground side switched, also I tried while cranking, and the scan tool does it without cranking it pulses them multiple times each, but the test falls silent, usually I can hear them
ok borrowed IDM and retested, koeo injector buzz test fires injectors now but still no start, IPR? I think I have been battling 2 problems from the very start
