XFI 2.0 was installed several years ago, a couple of days ago it quit suddenly without warning; now it won't even try to start- no spark, no fuel. Engine started running rough and then died; ECU showing no crank, points, or injector led's. Power led illuminates with key on and cam led blinks when engine is spun over. Ignition is Fast dual sync distributor, MSD crank trigger and ignition box; crank trigger and ignition box both check OK- not sure about the distributor, but the crank and cam led's on the pickup are both lighting up, so I assume it's OK. Checked the pins on the ECU connectors and none are loose or backed out, all fuses and connections are good and batteries are fully charged. Anyone have any thoughts or suggestions? Time to send the ECU back to Fast?
