Hi Nate,

Have you tried spraying starting fluid into the intake?? If the engine starts then we know that the fuel system is the problem and can go from there.

try unplugging the map senser. mine has done the same thing and every one thought that it wasn't getting any fuel. when acually the map sensor was causing the engin to flood on start up and wouldnt run. it might be a little harder on fuel, as is mine right now. but the car will start and run smooth. .... if your having the same trouble as i.
