Question about 1991 Pontiac Grand Am
My daughter has a 91 grand am, car starts up fine when engine cold, but once car gets warm it will either stall or if parked will not start again till cold. Pretty sure it is electrical car seems to lose spark when warm. Could it be ECM and how do you replace that?
Sounds more like your ignition module is getting hot and not working. I'd go there first before replacing the ECM. You can remove the ignition module and most NAPA stores have the ability to test them for you. Make sure they test it at least 5 times. This way it'll simulate starting and stopping.
