This car has been giving me a headache it starts and runs for 6 seconds then dies. I did some reading and found a thread talking about a ballast resistor. Any body have a clue of what the problem is?

There is a dual pressure fuel pump in the tank. The resistor is located on the inner front fender wall under the washer tank. it is to regulate the voltage for the fuel pump from start to using the supercharger. Locate that resistor, and to make sure its your problem bypass it with a piece of wire. Or use the test in this video

I used the relay test and the car wouldn't start at all. When up put the relay back the car went back to 🏃 then dieing in 6 seconds. Will try MAF sensor next. Thx

Are you sure you don't have a security issue? When you first turn on the ignition switch (not start), does the security light flash, then go off? Have you checked fuel pressure at start?
