Trying to start my fresh stroker build... No spark at all, here is what I've checked

Power to pink wires on each coilpack good
Power to pins 20 and 57 in the ECM plug
Changed crank sensor
Checked for any power at the crank sensor plug - none


I've looked over the grounds, all I have is the ground at the drivers rear head and ground at the front of passenger head. Is there any more grounds I'm missing?? I can't find any ground pin outs online

I read online that if you ad 12v to the crank sensors green wire it will work

I did that , and got 2 backfired out of it but nothing else.

I have an lq9 block but I'm running the gen 4 front cover and timing gear, and have the back sensor home plugged with a sensor.

I've tried stock tune, modded tune, vats and no vats, battery unhook etc.

Help please I'm desperate :/

Try posting this in the tuning section, they might be able to help you out more over there. I hope you get it figured out.

Crank sensor should have 5 volts at one of the wires during cranking
