I replaced the battery in my car. Since the turn signals flash FAST, and the fuel pump went out. Replaced fuel pump and now the car will run for about a mile then shut off. Restart and will run for about a mile then shut off. You could set your watch to when it's going to die. I put old battery back in, replaced the altinator and ign modual and also checked and cleaned all the grounds. It will idle fine for about a min then idle becomes rough but stays running. If u bring rpm's up to 2000 rpm's it will run for about 30sec then die continuously. Again can set ur watch to it. What else could it be? Computer?

Scan for codes and check fuelpressure with a gauge autoparts rent it. Check connections and fuses as well.

Be sure to check fuel pressure both when the car is running fine and when it is running like crap/not running.
