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,
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.
