Hello, i have an LS V8 Engine with VEMS 3.6.
Yesterday i was out and driveing, when my alternator suddenly stopped charging.
So the car stopped cause of to low voltage, i called a friend that came with a battery but it was not fully charged.
So we switched the battery and tried to start it but it was to low, for the v8 to crank, after testing another battery, that also was lo low for crank, did we try to see if we could fix the alternator issue, and charge my old battery by take a pair of jumpercables from his car, after a while, we had the jumper cabels on and tried to start it again, but then i was not able to connect to the ecu from my computer, and the fuel pump dit not run, now it was power enough to crank, but it didn´t start. Ive heard the fuel pump go when we had the bad batteries connected, and the computer was on saying that the battery voltage dropped to 6V when cranking.
We towed the car home and starting to fault check, i have 5v on the 5V supply EC36, pin 28.
If the Ecu should be fried should i have 5V on the pin 28?
Is it any idea to open the box up or shuld i just send it in for repair?
