April 8, 20205 yr My son and I recently purchased a 1990 Loyale for his first vehicle. Low miles, clean steel. It was running great for the first couple weeks then it wouldn't start at all. The starter is cranking but there's no fuel and no spark. We jumped the fuel pump and that seems to be working fine. Replaced the crankshaft position sensor which was in the distributor with no luck. Finally, we ordered a used ECM which claimed to work for about 90$ on eBay. Still no luck! Maybe we have two faulty ECMs? Or maybe we are missing something. Any leads or tips will be very appreciated!
April 9, 20205 yr Check your timing belts to make sure they’re still both in one piece. If you’re not getting spark you won’t get fuel. Also check your fuses and fusible links Cheers Bennie
April 9, 20205 yr If you have an ecm aka ecu, is it for some sort of fuel control of a carby? SPFi then? MPFi ?? My experience only lies with EA82T MPFi They use a diagnostic LED built into the ECU which often tells the problem, sometimes nothing related to problem You need to find how yours works It may be flashing a code or just indicate a healthy O2 sensor?? Or you may need to do the step byy step to get it to spit some codes I like Bennie's suggestion if timing belts, easiest check is dust cap off to see if rotor spins on cranking
April 10, 20205 yr Author Thank you both for your input! It's a throttle-body injection system. ECU 22611AA394 is the brain. the timing belts are uncovered but not broken. I've checked the fuses and relays. Our next move is to go through the wiring thoroughly looking for shorts or a burnt out link Edited April 10, 20205 yr by LoyalLion
April 10, 20205 yr You "checked" fuses,but,do you have power at the coil? Trouble codes? Ignition pulses at the coil transistor plug?(use a LED test light to avoid overloading the ECU.
