First, your engine should be a V6, not a 4-cylinder.
Your fuel pressure should be: 48-55 PSI (Pounds per Square Inch)
Vent the fuel tank vapors by loosening the fuel cap. Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel pressure valve. Confirm that no leaks are present, and with the key on, engine off verify the PSI reading on the gauge.
If I've helped you, pleas vote for me, as I depend on this to pay my bills. Thanx, Ernest.
