Q: Car will start but shuts off after 3 seconds on 1996 Buick Skylark

My 96 buick skylark will start stay on for 3 secs and shut off. Ive tried giving it gas and it shuts off instantly. If I start the car with my foot on the gas it will rev the engine but shut off almost instantly. Can someone help me figure this out and possibly a ball park on price?

Please take note of the "security" light on the dash off your 1996 Buick Skylark when trying to start your engine. If the light is flashing after the engine dies you may have a security issue causing your problem. Please see the following RepairPal article for more information on GM security system issues -
The fuel pressure regulator is most likely the problem. A replacement is about 65.00. The regulator is located on the injector fuel rail.
I agree with Oakman, all the signs, I know I had a 96 skylark, the security system is in the dash cluster and malfuntions, there is a company in Virgina that repairs them for $200
you may need a chip key..u will have to go to the dealer for this so they can program the key
The problem that you're having, if "Theft" light isn't flashing, is the MAP sensor. The MAP sensor malfunctioning will definitely cause the exact problems that you described. Unplug the MAP sensor, and if the car starts and runs.......then go grab another for under $40 bucks from Autozone. Take care!
I disconnected the map sensor, eng. still cuts off. the theft light is on not flashing.Can it still be the map?
