Since purchasing this car i have replaced the plugs, plug wires, distributer cap, rotor, fuel pump, fuel filter, MAF and the IAC. The last time the car started and stayed running i back up, it started sputtering, i gave it more gas and it backfired so hard that it blew off the oil cap. Ever since then, when i turn the key to start it, it starts runs for maybe 2 seconds and dies. I have checked both the fuel pump relay and the fuel injector relay. The car seems to have great fuel pressure since replacing the fuel pump. I have not been able to have the codes checked.
