What cause fuel system to loose pressure new fuel pump installed also new filter & relay pump cranks 65 psi a run until pressure drops and quits, it might start, fuel pressure regulator ?


if it cranks at 65 psi the problem will not be in the regulator as the pump is producing enough fuel to exceed what the injectors need
What is happening is that the pump is not capable of delivering enough fuel to maintain that pressure when running so look for venting problems , hoses collapsing internally or blockage in the tank pick up

In a 92 GMC Jimmy, Where is the Fuel Pressure regulator?


If this is the 4.3 liter the fuel pressure regulator is located in the intake valley. You will need to remove the upper half of the intake manifold, once removed you will see a small round regulator located at on end of the injector line.

92 GMC Jimmy Replaced fuel pressure and fuel filter, changed spark plugs and wires , no fuel pressure at valve, car will crank for 2-3 seconds then go dead


if you say you replaced the fuel pressure ? "regulator or pump" that was not very clear as to which so i am guessing and the filter but have no fuel to the fuel bar valve either you have no power to the pump or a clogged fuel line or a blown fuse or a short in the power suppluy to the fuel pump if you turn the key to on position without cranking it do you hear a slight humming noise if so the fuel pump is working ..if you do now hear this chances are as i stated above
the use of a test light is required to check for power to the pump as wel do you smell any gas =fuel lines are rotted .let ne know what you discover and check all your fuses
