Is the tuning 100% done? was the car working before? has something in the motor setup changed at all? have you checked for vaccuum leaks? clogged injectors? bad idle valve?

If The Fuel Pump Resister Is Bad It Will Run For About 5 Sec. And Restart And 5 Sec And So On. If Your Still Using It. I Jumped Mine Out So It Runs 12 Volts All The Time.

Why would you run the fuel pump resistor circuit on a Haltech???

If you arent hearing the fuel pump priming or the fuel pump relay clicking the ECU might have a bad circuit. Make sure its working or not, that might be it.

Other than that, the fuel pressure regulator might be toast.

that happened to rez's car when i did his haltech last weekend.

he was losing power to his coils for whatever reason. try running a wire from the battery to the leading coil and see if it stays running. if it does, you know what the problem is and can start looking into fixing it.
