Question about 1994 Pontiac Trans Sport
I have fuel,spark, injector pulse and correct fuel psi. Turn key to start and tries to start. Runs for 3sec or so and dies. New crank sensor, mass air flow. Van has problem with intermiten no start before, but would after setting. Ecm has been replaced. Fuel psi reg has been replaced. Still nothing. Any ideas? I don't own a scan tool and the van is not OBD2. By the way its a 3.8L
Some of those vans came with an anti-theft passlock system, it's a small chip in the key-- if equipped, the sensor in the ignition lock cylender failed alot with the early systems, with similar symptoms

Some models of other cars have same feature as mentioned... Chrysler for example where if batery is dissconnected you have to open and lock the driver side door 3 times for unlocking the system again... to ensure that you have the right key, worth a try perhapps :o)
