Anyone have trouble with 89-91 Xfi computers; I have two that won't run the fuel pump

Good bye


Just wondering if this is a common failure with this unit?

Never heard of it. Two of them giving fuel pump problems, I'd assume the problem is not the computer, but somewhere down the line of wires, fuses, relays, grounds, or the pump itself.

Any recent work done? Are the computer grounds at the back of the intake hooked up?

There is NO common failure on any Metro ECM/PCM, they very rarely go bad.

Good to know, this is on my Xfi conversion car. If i plug the old computer into the Xfi harness the pump will prime but of course the car won't run due to different pinouts for the ignition circuit. If I jump the relay to run the pump the car starts and runs fine.
