We haven't seen or worked on this machine for a few years, but the customer called the other day, no starting. One of my techs went out, I don't remember the code, but it could be the cam or crank sensor and he replaced both. He mentioned the cam sensor plug was cracked up on the outside. After this, he finally got it started and found he had a bad miss on one cylinder he thought. I ran him a compressor pressure tester to site, and checked again and found #3 and 4 cylinders not firing. We checked compression. Had well over 210 each, checked for an intake leak. All seemed fine. We installed new spark plugs in 3 and 4 ( yes- the special ones) and no help. We then swapped 3/4 coils with 1/2 coils and now 3/4 will run the engine, but 1/2 are no longer contributing. So.... We ordered two new coils and I went myself this morning to install. I tried to start the machine when I arrived, but it would crank and die. Installed the two coil packs, same result. I checked the 5 amp fuse at the injector and found that it was fine, but I would get a blinking voltage there, then when it started, the blinking would stop and the engine would die. I pulled the busted up plug loose from the cam sensor and I then get no "blinks" at the fuse, so this seems to indicate the problem?? Any ideas out there?

A little more info. After starting with a small cap of gasoline AND letting the machine warm up, it continued to start great. Even after sitting for several minutes. So it appears that when cold, it's gonna continue to start and die/ start and die. Has anyone seen this before?
This girl runs too smooth for that. Once I got it started, and it warmed up, it started right up every time. I'm going back in the AM and see what it does cold.
I just had one of those K25's that cracked the intake manifold causing starting, skipping, and idling problems. That round shaped runner heading to # 3 and #4 cylinders.
Ok, I'm back to customers. There is no code on the dash, my tech came by- pulled air cleaner cover from "carb", poured a cap full of gasoline inside , put cover back on along with bolts and snugged. The engine started and ran on all four cylinders (I had installed the two coil packs). So it appears that my problem goes away after starting. Any thoughts??
Thanks for the reply. Sorry, can't access with PC, but will be back there in about 1.5 hours and will recheck for dash codes.
is it possible you can read data on pc from the truck? it is much easyer.if not you must first check the lp gas pressure to the engine.
it must set on 0.35 , check crankshaft sensor , camshaft sensor , mafsensor in intake etc. do you have fault codes in dash?
