I have a 96 Jetta 2.0 aba 5 speed.
I seem to have a problem with the ECU activating the fuel pump relay. I intermittently lose power to fuel pump and injectors. I have power to the ECU and have switched it out with 2 other junk-yard ECUs. I have a tack reading so prolly not the crank censor?
Running out of ideas other the wiring but not sure where to start checking when it comes to wiring.
