A few weeks back, I checked ECM grounds and power, but it wouldn't hurt to do it again. Thanks

I thought I would update this. My car started and I was able to adjust the timing and take it for a spin around the block. I can't say I did anything or replaced anything, it just decided to start one afternoon. A few days later I tried to start it up to drive to work and it wouldn't. I turned, but there was no combustion. I left it until the weekend. After a bit of tesing on the fuel injector and ECM connector (the 10 pin conn), it started up, but when I attempted to take it for a drive it stuttered and stalled out in front of my neighbors house. I pushed it back to my place, thankfully it is not heavy and there was a downhill section. I tinkered with the fuel injector connector and it started up. I let it warm up fully and put it into test mode and drove around my neighborhood, but it stalled and died while driving. I tinkered again with the fuel inj conn and it started and got it home. So I am not saying it is the connector, that could be coincidence. I get continuity from the connector at the ECM to the fuel injector, and the fuel injector tests okay for resistance. This seems like an intermittent short. I don't know what I need to do to fix this to keep it from stalling out. Around the neighborhood is somewhat okay, but I work 20 miles away from home, and I don't want this breaking down on the I-90 bridges.

I have a 91 Loyale SPFI that died while driving down the freeway. I lost power, but the car was still running. If I stepped on the gas pedal, it would cough and die. I could turn it off and back on, but no change in condition. At home, it eventually stopped restarting. I replaced the coil, distributor cap, rotor, spark plugs and wires. All with no change in condition. I thought that the timing belt may have jumped a tooth since one of the belts was on, but loose along one side. I replaced it all with a new kit, etc. Again no change. I can see gas being sprayed into the throttle body, and I have okay compression, but I am getting a weak / intermittent spark out of the coil. The battery tests out fine, and when it starts to get weak from trying to start the car, I have a plug-in charger/jumper, so I know it is getting enough power on that end. All the fuses and fusible links test out okay. I pulled a junk yard coil, bracket, igniter, but again, no change. I have tested the distributor and crank angle sensor (inside distributor) and everything seems to be functioning there. I have the distributor / rotor lined up correctly. Does anyone know a way to test the ECM, apart from just replacing with another unit? Is there anything else you guys think that I am over looking? These cars seems so simple, that it is frustrating that this is so difficult. I don't know if the two problems are related (ignition and no accelerating power), but I hope that they are. One the bright side of all this, I am learning a lot about my Loyale. Thanks for any help, Paul Lastly, does anyone know what this thing is? It is inline to (or from) the ignition coil. It looks like a relay, it has a two pin connector going to it. One of the pins seems to be 12v and the other appears to be ground. The Haynes diagram seems to call it a condensor, but other than that I can't find any reference to it, or any info on what it does. It has "250V.DCO,47µF OH15" printed on it.

What was the end result? Did the dealership get anything sorted out for you?
