Fuel pump

Hello, I guess anything is possible. I would not suspect the pump without checking fuel pressure, and that is just a start. I'd also check voltage and ground at the pump, engine cranking. Are there any codes?

When you turn the key on, no crank, can you hear the pump run for a couple seconds? You really need a fuel pressure gage.

With the engine running the pump should be ON all the time. That is how the system works.
Now if your saying that the engine gets flooded with fuel, that is a different item. You will need to pull the upper intake and see if the fuel pressure regulator or an injector line has sprung a leak.

Yeah, you need to check fuel pressure. Go from there.

Hello, is the engine overheating? What does the temp gage show? Check the trouble codes, or have them checked. Use a fuel pressure gage and check fuel pressure. If you have that spider fuel system, they are noted for problems.

I guess you would know your average running temp better than I, 210 doesn't sound bad to me. I'd be checking the fuel system, if you think the problem is fuel.

It could be a bad pump, relay, wiring. Is the vehicle running with the one from Pep Boys?

Fuel pressure should be 55 PSI and above V6 3.8 W
if not fuel pump is at fault
when replacing fuel pump closely inspect connector wire as its very common failure and cause to a faulty fuel pump replacement

What about the fuel pressure regulator? I've seen lots of bad 1's!

The other should be a ground. There should be another connection for the fuel level sender. But the wire that turns on for a few seconds, it sounds like the system is working fine.

Good morning

The pump needs a battery voltage to run.

I attached a diagram for you. 12 volts is supplied to the control side of the relay to energize the load side. Check for that voltage with key on and cranking.

The load side has battery voltage all the time and is fed from a fusible link. It may be located at the starter solenoid.

Then when the relay energizes, it sends power to the module and then off to the pump.

Verify all powers to the components. I circled the fuses you need to test for power. This is not a visual test, you need to check for power with a test light or voltmeter.
