simple:

1)purchace 5 gallons of gas.

2) put car in neutral.

3)give it a push down a hill

4) light it

5)collect insurance money!

This of course, will not work, you WILL get caught.

The light is on for a reason, the computer has seen a fault. Knowing what the code set is will help in resolving it. Offering the code number will allow me to assist. Ray

I have a '92 LeSabre 3800, the service engine light came on the Dealership said diagnostic showed no codes...so driving it home it died...so the dealership replaced the Oxygen senser on the exhaust...300 miles away from home it stalled on the Interstate drifted to the side of the in the hot summer sun and sat for an hour... It would crank okay but not start then it started up and no problems for a week...then the service engine light came on. Took the car to another Mechanic and diagnostic showed no codes. He said no codes pointed to a faulty positive pressure fuel pump sensor...so I replaced the fuel pump, sensor, and inline fuel filter then the car won't start at all. So we check for codes again none show up. So we replace the ECM Prom and the Car seems to run okay around town then it dies in traffic...but starts up in an hour. Any way here is the Service Number 16141470 on the ECM it has one green and two blue harness connectors. Also the '92 LeSabre has a DSI security package integrated...could it be at fault?
