Engine Performance problem
1994 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic 136000 miles
I am an mechanic and have replaced the coil packs/plugs/housing/ignition module/boots/fuelpump/fuelfilter and still. When the car is cold it starts right up and idles perfectly, it will drive fine but after about 10mins of running it shuts off, no sputtering/coughing, just like you turned off the key. It will crank all day long but not restart, the fuel pump does run for a few secs on each key turn. If you wait 20mins or so it will start again but only for a minute or so. This sounds thermal reltated but I am at a loss as what to look at/for. The Passlock alarm system was bypassed years ago so dont see that as an issue. Any ideas please !
have the same problem?
