new lt1 crank, no start issues.
okay guys, well i'm still having issues with my car cranking, but will not actually start.
i have 45lbs of fuel pressure, new opti, i'm getting spark from both the coil and the distributor at the plugs, noid lights confirmed that i'm getting absolutely no pulse at the injector harness, and with a multimeter, i'm not even getting a constant 12v at the injector harness w/ key on. opti pigtail is getting the 5v at two of the wires. and i'm getting 12 at the coil/icm harness at several points. Pcmforless tune deleting vats,egr,air, etc. and i'm getting nothing at the injectors. if i provide fuel for the motor through the intake it will start, and run for a few moments until that fuel is burned up. i'm absolutely stumped. the car will crank and crank, but will not actually fire up and run on it's own.
needless to say, help guys.

it ended up being the wires that regularly go over the passenger side fender, but i did the wire mod, and relocated that entire harness to go under the fans instead of in front of the radiator support, and two of the solder joints that i soldered broke somehow, and i guess they just so happened to be the few wires that go to the injector fuses cause immediately upon fixing these wires i had 12v at the injector harness. lucky, i only ended up extending two parts of the harness itself being these wires, and the ones going to the coil since i relocated it as well, so seeing that i had spark, this was my first place at checking the harness and it ended up being the problem, so i didn't have to go through anymore of the harness. such a relief.
