All of the fuel injection parts are from the car, I replaced the fuel meter boot and cleaned the CIS unit, cleaned the IAC valve as well. I ended up basically replacing the long block and transferring all of the bolt on parts.

When the FPR was jumped it ran exceptionally well, aside from the high idle.

I am thinking that the "good" JY FPR I tested it with maybe was bad and that is the issue, but not sure how or if the Tachometer is tied into that system.

Maybe the ECU is bad, but I am not sure what the symptoms of that would be.
