My car dies because it's not getting gas, so I replaced the fuel pump, that didn't work, so I replaced the filters, and that didn't work. So I wanted to replace the relay and I can't seem to locate it. Could you tell me if that might be the problem and where to find it?

How do you know the fuel pump is good ? Did you do a fuel pump pressure test with a test gauge ? Did you test the fuel pump electric circuit ? Is the check engine light on ? There is a fuel pump relay under the hood engine compartment . The right front behind the headlamp are four relays , the one to the left is the fuel pump relay .I'll send a link to a video on testing the circuit !There also is a fuse in the wiring near those relays , it's power for the fuel pump relay ! Or you have a bad fuel pressure regulator ! A plugged catalytic converter could do this , need to pull the O2 sensor an do a back pressure Test !

When your replaced the pump did you replace the fuel filter? You may have a fuel pump relay causing you some grief. I believe it is located in the engine compartment in the fuse center on the left inner fender. Check the relay and any related fuses. Check the electrical connection at the pump. They had problems with some of them and they would get kind of hot and distort and corrode. They have new updated ones that can be easily installed.
Yes, there is a Fuel Pump Relay. The Relay is located on the firewall just above the left-hand (even cyclinders) valve cover as viewed from the front of the car. There is also fuel pump test lead attached to the harness at the fuel pump relay. Attach a power wire from the battery to the lead and the fuel pump should come on. If fuel pump comes on, the relay could be bad. Also check the fuel filter located under the passenger side of the truck tucked into the frame rail.
Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.
Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe
