View Full Version : Still no short run power

05-10-09, 02:53 PM
I added new spark plug wires and the car does run more strong but im still getting lack of power on the gas. It's good on the long run but from a red light it takes a few seconds to lift off. I did notice this only happens when the gas is about half tank, on full tank it runs more quicker. I need help!!

Put a fuel pressure gauge on the service port on the fuel rail. Turn the key on to energize the fuel pump and read the gauge. Might also tape the gauge to your windshield and take it for a ride. Observe the pressure when the problem is current.
