Check the Ne, G, Igt, and Igf wiring back to the computer.

If the computer don't get the Ne and G signals it will not give an Igt signal tell the ignitor to fire the coil and no Igf meaning no combustion occurred.

I have checked at the ecm with a ohm meter on beep test when i crank the veh i hear a a tone every time a single is sent to the ecm. from wire G- to G1 and G- to NE that is why i am so troubled. I have a dealer repair manual i feel like i am missing a sensor or relay but am so upside down i feel lost

thank for trying
