Hey guys, bought a LT8 from a mate of mine and was told that it was in perfect working order.

I wired it up into my existing harness as I have redone all the wiring on the harness previously for the Apexi PFC and everything was working perfectly and car fired up no problem, I triple checked that all the wiring was done correctly for the mircotech and connected the battery, I only get the green light when I turn the ignition to the on position, when cranking nothing flashes or anything, fuel pump also doesn't prime when turing on ignition.

Checked power to injectors, ignitor and fuel pump and all get 12.8v.
Bench tested fuel pump through relay and turns on no problem.

I also noticed that my fans turn on when I turn the ignition on which never happened before?

My question is as follows:

Is the ECU fried?

 

Had the unit tested and pre drivers are fired, so time for a new one.
