i've been battling a problem that arose at random over the past week. the problem started with when i would rev the car it would randomly shut off like the ECU was shutting everything down. so after countless hours trying to diagnose the problem i cannot figure it out for the life of me. i have talked with marc on the problem a little and we cannot find any solution let alone the cause of the problem. i have replaced both crank sensors with ones off of my daily driver S6, put a brand new cam sensor on the car, swapped in another set of cam sensors from another parts engine, i have the crank home wires flipped at the plug rack on the fire wall, i made sure pin 48 on the motronic connector was grounded as another person suggested, i even removed my complete engine harness and went over it with a multimeter checking for breaks and all of this has brought no resolution to the problem. the car is an 84 4000s quattro with a full AAN swap by the way. last time i ran the car i had fuel pump failure and the car sat for a month till i bought a new bosch 044 pump for it. the only thing that has changed since it ran fine was the fuel pump. i have the pump wired to a relay and everything. i figured i could pick a few brains on here and see if anyone might have had this problem and found a solution.
Here's a few of the recent trigger logs in a ZIP file.
