1991 Buick Park Avenue no start

I haven't had good experiences with autostores checking parts for me. I do my own testing, where possible. When you turn the key to crank, can you tell if there is a load on the starter circuit? Watch the dash lites--dome lite--headlites, something, if there is load on the starter, the lites should dim, go out or something? The site doesn't like to tell people how to bypass anything for testing, because of possible safety issue and the person may get something hooked up wrong and cause more problems than they already had. You can use a remote starter button to see if starter will crank, maybe the leads are long enough to get you out from under the vehicle. The leads clip to the proper terminals at the starter solenoid. Make sure the tranny is in park or neutral and a functional e-brake is set. You don't have to use the key, just hit the remote button, see if it will crank. Any testing is your responsibility.

Also, there might a problem with voltage or ground circuits. If there is a big load on the starter circuit and no action, maybe an internal engine problem?

Could be the starter, starter relay/park and neutral switch and ignition switch assuming the battery and connections are good.

Hey razmataz, have a good holiday man.

Same to you JDL and take care be sound and safe
