Default Fuel pump, right?

Today I got off work and was pretty low on gas so I shot across the street and filled her up. 25.2 gallons later she's all full.

Go to start it and it cranks and starts, runs for about 1 second then dies. Try to restart it and it's just cranking and cranking.

It's really windy and normally I can hear when the fuel pump primes when I turn the key but I wasn't hearing anything over the wind.

Went ahead and primed it 5 or 6 times by turning the key on or off, popped the hood and poked at the Schrader valve on the fuel rail. No fuel came out.
Shouldn't some have come out given the fuel rail was (or should have been) full of gas?

Went ahead and swapped the fuel pump relay with the horn relay, still won't fire.

At this point I'm like 80% sure my fuel pump went out. So I grab a can of starting fluid and spray some down the throttle body. Go to start it and it fires right up then dies after about a second.

So now I'm like 95% sure I've got a dead fuel pump

Does that sound right? Anything I'm overlooking?

Sounds like the fuel pump. There should always be an audible whine when the key is turned to allow the system to pressurize. Most people always turn the key straight to start, but when my son was learning to drive, I emphasized to him to listen for that whine and only turn the key when it ceased.

That being said, you can try banging the fuel tank or the top of the pump with a 2x4. Sometimes, that will elicit a bit of life to get you home, but either way, that guy "Murphy" struck -- full tank of gas and the fuel pump dies.

Yeah I had to work that part in there, worst possible time for the fuel pump to go out.

I dropped the tank and naturally my pump died with 3/4 of a tank of gas, and it sucked. Yank the bed off!!

Did you check the fuse? Jump out the relay? Unlikely but may want to make sure it's the pump before you replace it.

No I just swapped the relay.

I just finished pulling the old pump out and it was factory. My truck has 196,000 miles so if it is a fuse or something I'm still glad I'm changing out the fuel pump.

Don't forget to line up the arrows when putting the new pump in..
