Hi and welcome to FixYa!
The fuel pump relay regulates the power given to the fuel pump. If the fuel pump relay is faulty there will be no power to the fuel pump and will result to fuel supply failure. These relays just like the others serves as regulators so that the battery will not fail during electrical loads.

Hope this helps and thank you for using FixYa! Have a good one!

Fuel pump relay works off power supplied from ignition switch to fuel pump but has separate lead (ground) that runs off oil pressure switch (safety) If your vehicle would roll-over, be involved in an accident or your engine would lose oil pressure it shuts down fuel pump.

Try the crankshaft position sensor. Sometimes they get covered in clutch dust and the sensor cannot determine No1 cyl. and then it will refuse to start. Sometimes they go faulty as well.

Did you install a new pump? Used pumps may be cheaper but not if you have to change them.

My 88 ramvan did the same thing and it was the pickup sensor in the distributor. I replaced it and everything was fine. If the sensor is bad it won't let the fuel pump run or the ignition funtion.

Cranks but wont start


Someone will need to check the circuit at the pump to see if it is getting power from the relay. If it is the pump should be running when you first turn the key on.
You can also check for power at the pump relay.

Yes, it can be the relay. What I do is unplug the relay and swap it gor yhe horn relay. If this doesn't work, I use a volt/ohmmeter to probe the relay socket. Doing this, I can usually find the problem. With the key on , there should be two terminals in the socket that have battery voltage and one that is grounded. The last terminal goes to the pump and should show low ohms to ground. In your truck, the relay coil is connected to ground and turned on by the ecm with a positive signal. It also seems to depend on the oil pressure switch, so you might want to temporarily bypass the switch with a paper clip in the connector to see if that is keeeping the pump from running.

My 2003 chevy silverondo feul pump stops working . have changed feul pump worked good for week and started doing it again. will start up again but who knows when


Did you replace the wire harness from the new sending unit to the frame??the old one tends to break when moved around causing issues and also inspect the ground wire also to ensure that it's still has a great ground on the frame from the harness.

The other thing also is that you may want to replace the fuel pump relay just to make sure it's now faulty. Just swap it out with another relay in the relay box.

Good luck and keep us posted.
