I know its a fuel issue

I took my truck for its 1st trip this saturday and it failed. I was cruising down the hwy and had been about 50 miles when it just slowly died. Pulled over and flipped tanks back and fourth and finally it started.

I have read about the lines in the tank being bad so I tried to fill up the tanks. the rear tank held 4 gallons and the front 2 gallons. drove to our destination about 20 more miles and it ran fine.

coming home it died again.started back up after switching tanks and waiting and alot of cranking. It made it a mile from the house and it was done.

today I pulled the fuel filter and it only had about an inch of fuel in it. I filled the new one with atf and had to bleed it for a sec and just a little shot of ether and she cranked. from what I have read I am thinking lifter pump.

where is the pump? I really cant test it because its intermitent. Am I on the right track?

Well a simple test that could rule a few things out would be to disconnect the line that your lift pump pulls fuel from and run a line into a container with atleast a gallon of diesel in it.

If it starts after cranking all the air out, and continues to run. Your problem is likely clogged fuel lines from your lift pump back. Or failed fuel tank selector valve.

If it doesnt start take 9/16 socket pull the two bolts out of the lift pump gently pull the old lift pump off the block, fine a solid asphalt ground (Concrete, possibly cinderblock would work too) go to tool shed, grab biggest hammer you can find and proceed with smashing that old peice of crap until you cant recognize what it was anymore.

Then get a good quality epump from I believe it was type4, and install it.

Or just go get another from your local autoparts store they are pretty cheap.

go to this link https://www.ford-trucks.com/forums/8...ont-start.html and scroll down till you see some odd shaped metal think with a black arm. Thats what It looks like.

well they use a big block Chevy block off plate for when you convert to an e-pump so....... don't wait to long b/c if the diaphragm in the pump fails you will be pumping diesel right into the crankcase.

Okay I am offically an idiot

. I pulled my sending units to day just to double check to see if the pick ups had come off ,but I was allmost sure they were fine when I changed the floats. So guess what,,,, both tanks are empty lol.

I could have sworn that I had filled them up a month ago and I discovered that the tank switch was dirty and not working right and the rear tank reads right if I wiggle the plug so I will work on that tonight. They both read empty now

like they should

How much fuel does the front and rear tanks hold? Im pretty sure I have an issue with the way the filler necks are rigged when I did the flat bed and thats why it would not take any fuel. I will fill them up this weekend and take a cruise to the foothills and see if Im right.
