Well a few days ago I posted how I was getting rid of her, but she doesn't want to go, which makes me want her to go more.

It was setting on a slight incline, front of the truck going down, pretty slight nothing that would cause gas to be too far from intake

but i tried 3 different days to crank her(several times a day) (didn't have time nor Initiative to look at her) the try before she finally cranked I put 2 more gallons of gas in her and she finally hit it, I doubt it's the guages, very highly.

the fuel filter (under the driver side door) was changed not too long ago.



So I'm wondering if there is another filter that is directly connected to the tank, that I perhaps washed some trash out of the way of the for gas to flow or what?

It drives well... other then a barely audible slight knock.

Any ideas?

At 120k miles, it's probably your fuel pump. Plenty of write ups on this site on that subject doing a search.

It's happened before only not taking nearly as long to crank, and it runs just fine when it is cranked..

So kinda what I'm asking here even if the fuel pump is going bad is it normal that once cranked it still runs?
