Question about 1995 Buick Riviera
I had a problem with the car shutting down. changed the crank sensor.
ecm was found to be faulty, so was changed. worked for a while and dies again. put old one back on it works for a while. even if you just unplug the ecm and replug it the car fires up no problem. could it be a spike that is shutting the ecm down? thanks ****
I have seen so few ECM that cause your symptoms, do you know what you are loosing when it "shuts down" spark, ignition, fuel pump 5 volt ref? If I was sorking on it Id have to check all the ECM grounds there are several, and make sure all the incoming powers are constant and keep equipment hooked up and check to see what is missing when it acts up.
Please let me know how it goes so I can recommend net next course of diagnostics follow-up at
