| You are perfectly right, replacing parts without testing is really a big waste.
I dont know if you tried this: short the terminals in the fuel pump relay socket that correspond to fuel pump relay pins 30 and 87. Use a thick short wire, around 8-10A will flow thru it. Drive around like this for a while and see if the problem is gone. If it is, then you need a new fuel pump relay. If problem occurs, it is in a place other than the fuel pump relay.
If the problem persists, then bypass the OVP relay for a while. Same pins for this relay also, 30 and 87. Caution: But before doing this, make sure that you do not get more than 14V on the battery terminal for all RPMs. |
