Backprobe the 6 position connector where the injector harness plugs into the engine harness. Google backprobing to see what it is. With the connectors still plugged together and with the engine running check the pink and the pink black wires. Each should have +12v on them. Next using the probe check the Lt. Blue and Lt. Green wires. Each should show +12v most of the time and should show ground quickly.

If you aren't getting the 12v on the pinks check the fuses.

If you are getting the pulses on only one of the lt blue or lt green wires you might have a wiring problem or a bad ECM.



You nailed it sir, the injectors are the problem, the fuse was blown on one bank of the injectors, after testing all of them i only had 2 fireing, and i could not get those to spray with the test kit i have... thank you very much!!!

Check that both fuel injector fuses are good. (Don't just look at them.)
