Sparatically losing power to my high side fuel pump. Mechanic spread apart pins in wiring harness to ecu. It ran for half a day and shut back down. Was able to unplug ecu and plug it back together and then ran great to get back to dock. It did this a few times and was able to get it going with same process. Do I have to replace ecu as the pin side of plug is connected to it?
Is it loose connections or is my ecu going bad.
Cant find a new ecu as they have been discontinued.
If I buy a used one what’s the odds of having the same problem?
