I pulled my motor and had slight engine modifications done. I know you cant do much or else you can throw off the computer. My problem starts with my fuel pressure, i checked it and its 32psi and it supposed to be 35-40psi so im off by about 8 psi from the desired. The thing is that it will only read with the car running not with the key forward like its supposed to be. Also when i shut the key off and turn the key forward agian (not starting) the guage jumps and then loses pressure. I know the pump is supplying the volume because it jumps when i rev the car up, but when im driving it the car has trouble starting in the cold and it also falls on its face when i stomp on the gas from a stop. I know the car should have more get up and go than this. Im desperate for advice and any would be helpful.
Replace the fuel pressure regulator unit

Do you have any of you fuel lines close to the exhaust? (vapor lock)
SOURCE: cant get enough fuel pressure to run properly

SOURCE: 96 Probe GT. Fuel pump doesn't run when it should.
Does your car run? Some fuel pumps run quiet so you will need to get your ear close to the gas tank and have someone turn on the ignition. The pumps only run about 3 seconds when the ignition is turn on without starting the engine.
SOURCE: Mustang stalls when trying to drive and will shut down
Measure fuel pressure on injector rail - should be 38 to 40 psi. If low or fluctuating, then replace regulator. Another possibility is the in-tank filter being clogged - rare I know, but trash in the gas tank and it's clogged.
