problematic relay board - can not get power for fuel pump from side of board to the other. did search and note some have stripped and rebuilt them. so does anyone:
1. have an inexpensive rebuilt option; 2. know of a service or shop that does this; 3. have a fix to simply wire around problem? thanks in advance for any help. |

we can jump it at the relay to get it to work. hmm. You do understand that the pump only runs for a second when you key on. It then stops until the ecu detects that the engine is turning over. You can over ride this by removing the 4 pin plug at the back left of the relay board and jumpering pin 3 to ground. Then the pump will run continuously. That's how I have my car wired--except I've added a Ford "Fuel Pump Inertial Switch" (FPIS) to kill the pump in case of an accident. It's simply wired in between pin 3 and the ground. The FPIS can also be "popped" if I want to keep the car from being started (at least they'd have to look for the "problem"). |
