I think my ECU failed but I've heard "they never fail". Went to start the car today and didn't hear the normal 1.5 sec fuel pump run and injectors click. Tried starting anyway and cranks but didn't fire as expected.
Checked power at fuel pump with a helper turning the key and no power. Went through Jeff Bowlsby's fuel pump troubleshooting list and relays, relay board, wire harness all checked out. So I pulled the ECU 028000052 and replaced it with a spare ECU 0280000037. Turned key to start position and fuel pump ran and injectors clicked. Started the car but the idle was rough and eventually died. I think the 0280000037 isn't compatible. Car is a 75, Engine 74 case/exhaust 2.0L MPS - 0280100043 CHT Sensor - 0280130012 Distributor - 0231174001 Engine ran great before this problem with no issues. It has 2k miles since rebuild and being sorted out at a reputable shop. Any advice welcomed. thanks, Michael |
