The car starts with no problem and runs perfect for about 10 seconds then it dies. It seems like it runs out of fuel. I installed a new fuel pump. Jumping the diagnostic box and the pump runs and generates 48PSI but when the engine runs there is less than 20PSI. I installed another pressure regulator but nothing changed. I wonder if a bad vacuum solenoid would cause this condition? I'm not certain how to test for that.
Why does my engine die after running 10 seconds but will restart & run for 10sec on 1993 Mazda Protege
