I am trying to get my 73 2.0 with EFI running. I figured out that I am not getting any power from the ECU to the fuel pump relay. Is there a way to test the ECU? Which pin is the power feed to the ECU? Does anyone in the USA fix these and if so is it a common part that goes out? Is is sometime that a guy with a soder gun could replace?
Thanks for the help. Tony Modesto |

Is there something specific that makesyou suspect the ECU? ECU failures are pretty much the lowest probablity for fuel pump problems. All it is doing is closing a switch to ground. The two relays and fuse are the prime suspects. Wiring harness next on the list. Search on fuel pump - lots of good threads there.
Quick check to tell if the ecu is the problem. Remove the 4 pin connector on the back left of the relay board. Jump pin 3 to ground. Turn the key on. If the pump runs then your ecu or the harness to it is suspect. If it doesn't run then look on the relay board for problems. |
