Thread: Car starts but stalls after 2 seconds

Please note that if you are a smoker do not have any open flames or sparks present when performing this test.........

To diagnose this we need to determine if the issue is fuel or spark. The rest we should be able to accept as working properly.

Pull a wire off a coil pack and crank over. See sparks jumping around? If yes..spark tests concluded. We will assume the wires and plugs are new/good.

Next up.. Get a piece of vaccume hose about 8 or so inches and hook it to the LIM vacuum port under the snout of the SC. Using a can of highly flammable brake cleaner.. start the car and mist the cleaner into the vacuum line with the tube that comes with the can. If the car continues to run past the normal, then your issue is fuel.

Your symptoms sound like you have a security issue and need to security relearn the car.
