Where is the fuel pressure regulator/sensor located?

Hello, sorry to hear you are having problems. I'll do what I can to help you out. Even though you can hear the fuel pump running, it may not be providing enough pressure or volume. If you can test the fuel pressure at the fuel rail, the pressure should be about 45-57 PSI with the engine running. We have had problems in the past with the fuel rail pressure sensor, but it will usually set a code. I have uploaded a diagram that shows the location of the sensor on the fuel rail. If you decide to replace the fuel pressure sensor you will want to lube the o-ring lightly.

This fuel rail has no place for a pressure sensor, The fuel pump is holding 55 PSI when cranking and has no bleed down for 10 minutes, my guess is the fuel pump module controls the pressure. Thank you for any help you can give.

Sorry for the confusion on the sensor. On your vehicle the pressure regulator is in the pump module. The fuel pressure is fine. Do you have access to a scan tool that can read live data? If the car runs for a short time and then dies, it may be due to a faulty sensor reading when the PCM goes into closed loop.

Thank you for responding. It will only start if i use starting fluid and when i stop spraying it will stop. but i have noticed that when the engine starts to get warmer it tends to run longer after i stop spraying the starting fluid it ran 1 time for over a minute then shut off. and the scan tool showed no codes. Thank you

I think i might have found the problem, found an intake leak between cylinders 2/3 and when you move the intake runner manually you hear a sucking sound. Your thoughts?

Thanks for the update. A leaking intake manifold can definitely cause your problem. As far as the intake runner goes, I don't think there is an issue. When the runner is shortened it will change the turbulence in the intake. I would proceed with the repair of the leak.
