Fuel pressure switch ???? Fuel pump relay maybe , no fuel pressure switch . Looking at a wiring diagram for the fuel pump electrical circuit too see what all is involved an then using a DVOM - digital volt ohmmeter to test the fuel pump electrical circuit is how to find the problem .

You need to do a fuel pressure check.. You will need a special fuel gauge and the appropriate fittings and adapters are needed to properly test the fuel pressure.
1. Relieve the fuel pressure.
Remove the fuel pump relay form the Power Distribution Center (PDC) Start the engine and run until it stalls. attempt restating the engine until it will no longer run. Turn the ignition key off. Disconnect the cable from the negative battery terminal. Replace the fuel pump relay in the PDC. Any if you get any trouble codes at this time you will need to see a shop to have them cleared.
2. Disconnect the quick-connect fuel line fitting fuel gauge into the fuel line using the appropriate T-fitting and adapters.
3. Start the engine and check the pressure on the gauge, your reading should be 49 PSI with the pressure with the engine idling.
4. if the fuel pressure is not 49 PSI:
1) if fuel pressure is higher you could have a pinched of clogged fuel return hose of pipe. if the line is not obstructed check the fuel pressure regulator.
2) if fuel pressure is lower check the fuel filter, look for a pinched of clogged fuel hose between the tank and the fuel rail. check the pressure regulator for malfunctions. Look for leaks in the fuel line.
Hope this helps.

Go to the autozone website at autozone.com and register your vehicle. It's free and will give you access to an online repair manual for your vehicle. The procedures for changing the fuel pump should be available there. Sure hope this helped and best wishes.

Try to do the crank relearn:
Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.

1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start). Allow the key to return to the on position. (same as if the vehicle would have started)
2. The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.
Thank you for using fixya and keep me posted, be glad to help you get your jimmy running 100%

hi, i;ve never worked on one of these, but, it must have an electrical fuel pump. the easiest way to check this is to jack the car up and look up under the rear and near the fuel tank. these pumps are INLINE meaning FUEL PIPE IN THE CENTRE (IN) arrowed toward the engine and FUEL PIPE IN THE CENTRE (OUT). these have 2 conectins IGNITION FEED and GROUND. if you switch on ignition and NO FUEL. then NO IGNITION FEED / RELAY / BAD CONNECTION / NO EARTH / COMPLETE DISCONECTION / FUEL PUMP BLOCKED / FUEL PUMP (INTERNALALLY OPEN CIRCUIT pump needs replacing). i hope this has helped. gerry

Fuel Filter Replacement Procedure
1. The fuel filter is located on top of the fuel tank near the fuel pump module. Fuel lines are permanently attached to filter assembly and must be replaced with the fuel filter.
2. Release pressure from fuel system by removing the fuel pump relay and start the engine and let it die. Crank the engine a couple times after it dies to relieve more of the fuel pressure
3. Disconnect negative battery cable
4. Raise and support vehicle
5. Support fuel tank with transmission jack or floor jack with large plywood board to evenly distribute the weight of the fuel tank. NOTE: It is important to distribute weight evenly to prevent damage to the fuel pump module.
6. Disconnect ground strap from fuel tank
7. Remove inboard fuel tank straps and front "T" strap fastener
8. Lower the fuel tank approximately 6 inches to access the fuel filter assembly.
9. Disconnect the fuel lines at the fuel supply connector and the fuel pump module
10. Remove the retaining bolt and remove filter assembly from vehicle.
11. Reverse removal procedure to install (Don't forget to put the fuel pump relay back )
