Chevrolet Truck Fuse Problem
Truck died going down the road. Would not restart only attempted to start now after getting it home it only cranks . After sometime looking at it i have confirmed that we have spark, compression, 60psi of fuel pressure.I have changed out the ECM, crank sensor, cam sensor. Used a multimeter and have no power to the fuel injectors ( have not tested with a Noid light yet). So i would say that this is fuel problem but the head scratcher is that is we dump gas or spary starting fluid down the intake I still get nothing not so much as even a pop bang or back fire. Which first led me to believe it could be a timing chain( this was before i found the power issue at the injectors) but the distributor turns when you crank it over so it cant be the timing.

do a compression test to see what the figure is. that will tell you if you have timing chain issue
put the old pcm back in the truck. unless you got a new one and had it flashed to your truck
power to the injectors is controlled by a fuse. check them with a test light. the pcm only controls the ground side

Compression checked out good. Old PCM is back in truck. Any more info on which fuse in perticular i should be looking for? IGN fuse or ecm fuse?
