The build date is 12/91 on the door. I noticed that the other day. Was going to hit the parts store with the 91 year and see what they find.

Where is the ECU and PCM located on this car anyway?

Installed new temp sensor yesterday. Started overheating so I imagine that I got an air pocket by the thermostat. Anywho, bled it out this AM and started it up. Same thing.

Still completely shuts down once it'* a tad warmed up. Still have great spark too. Seems like it'* not getting fuel.

Any other suggestions? I am at my wits end with this car. Soon to be stripped of all my new parts and brought to the crusher on Tuesday. AUGH.

Ok. Would this be related to the SECURITY light? Its on now and the car turns over and won't start. Does the security system have any way of shutting down the fuel as the car is running? Seems that the Security light comes on and the car stalls.


Ideas?
