Help understadning my CJ7 SBC datalog

so with your DMM referenced to ground, negative lead on battery or chassis, you want to see if you have 12+ volts on the WHITE and RED wires with key on. you can then check continuity to ground on the BLUE and GREEN wires. with the engine NOT running you should have no continuity to ground. should only have pulsed ground when the engine is running if my thinking is correct. you can then check the ground with engine running and see what its doing. i am wondering if you have a poor connection at the injector or a bad #2 injector driver in ECM if all the wires rang out OK... keep us posted

EDIT; not sure how Howell has setup your system, if the 430 wire isnt there and ran before i would expect it to not be the problem.

EDIT 2: I SWARE i've seen each injector fused separately by GM in the past but i may be remembering wrong, i assume Howell has an auxiliary fuse block and you've verified all the fuses are good there?
