AAARGH- help starting issues At my wits end.
Ls swap 01 4.8 in a 69 Cutlass, stand alone ebay harness.
I have had this car running without problems , now suddenly I have intermittent ecu power problems. I'm pretty sure it is an ecu connection problem. I have 12 volts at both the trigger wire and the fuel pump relay, but everytime it works it only works for a few starts and then no fuel pump relay and no obd connection. Should I replace the harness or the the ECU? stand alone ebay harness, 01 vortec motor with VATS delete done. not sure why it suddenly is not working. I have disconnected the ecu at least 10 times- even tried repinning the blue harness with the original connector worked for 2 starts, then no relay clicks
