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.

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.
