Fuel pump replacement

[casper4203]

I'm pretty sure my fuel pump took a dump on me today. My tank is completely full.
Would it be easier to pull the bed off instead of dropping a full tank?

Ur fuel pump is on the driver side frame rail, im going to replace mine tommorow bc its acting wierd, one day its 60-64psi and goes as low was 59Psi 2 WOT.....next day its hovering around 55psi and drops off bad under acceleration. its pretty easy to change look under the driver side on the truck

Have you checked the fuses and relay, the anti tipover switch do you get power at the fuel pump plug?

Yesterday it started acting like the fuel filters were choking up. I had a set and made it to a friends house to change them. I could not get any fuel to pump into the filter bowl on top. I checked the fuse and it was good. After checking on here, I see now that its the unit under the driver's side. Thats better than what I thought as far as dropping the tank

Pull the lines off the pump. See if it will pump diesel out of a container and then back into something else just so you can see it.
If it does, I'd check inside the tank and see what happened.
If not, HFCM.

agreed! the pump is also pretty loud put your ear to the ground koeo you should hear it coming on.

Codes said low fuel pressure.
Checked the voltage at the pump and that was good.
Replaced the pump and we're "on the road again"
