okay, so I have been working on my '99 Silverado 1500 that had been sitting for over a year. I had to change the gumed up fuel pump. Now that its "running" its down a cylinder (I believe its #2, front passenger) I unpluged each coil and the 5.3 studders a lot more when each is unpluged except for the one, so I poped another plug in... not the problem. So I unpluged the boot from the coil, I get the arc on all coils except for the one. So i run up to autozone and pop a new coil in.... agin not the problem. Oviously it is not getting power... I did not have a test light with me only a DMM I could only seem to meter 12+ constant. Any ideas???

Stuff plugged in? You sure the injector is popping on that cylinder? Fuse block? Relays?

well I still cant seem to find the problem... My only idea left is to ohm out the wires to the ECM. If anyone has a pin out of the ECM that would be awesome. (the truck has a 5.3 if that matters)
