Ok, so I went out to crank the truck and... nothing. Started doing some more checking with the multimeter. Relay is clicking, ok. I have power at the test port, ok. Everything else is working, ok. Pulled the high pressure pump, and it's dead. I've had it for a week. What the ____ is happening here?

 

Not sure why this warrants another thread but that's what I said on the other one while you made this one.

 

It will die if the tank pump isn't feeding it fuel. You said it was noisy, they are noisy when they aren't getting fuel. Looks like you need two pumps now.

Oh goody.

 

I had this problem last year. Truck ate 3 fuel pumps(2 front, 1 back) in a 3 month period.

The problem ended up being that there was too much rust and other debris/gunk in both of my tanks.

I ended up replacing both tanks and both pumps, and its been problem free for over 15,000 miles!

 

Hmmm...

 

Take a fuel filter that is clogged and take it apart one day. While looking at the filter media just think, ALL that crap made it past the fuel pump strainers. Since the addition of ethanol, the situation with steel tanks is only exacerbated from the water condensation. We should all have a no ethanol petition.

 

^yep. The ethanol-ed gasoline F***s up small engines too.
