need help ASAP, truck won't start

[Bray D]

I just relocated my fuel tank 2 weeks ago, I've run 3 full tanks of gas through it with no problems. I was cruisin yesterday and my truck sputters and dies. I've had my fuel line come off my fuel filter before and this is exactly how it acted. crawled under and didn't see any fuel leaks. when I turn my key the fuel pump wines so I know it's working. my fuel filler hose runs up into my bed, uncoverred so I thought maybe I got some water in my tank. picked up a bottle of HEET, dumped it in there and still wouldn't start. had a buddy tow my into town, then tried jump starting it, nothing. it'll turn over and fire while the starter is turning but never catch and stay running. any ideas?

well I just put in a new fuel filter and after a lot of tries it started for a little bit. had a super eratic idle. it fired and jumped up to 1800 which is normal for when its cold then it dropped down to less than 500 then would pick back up to 1500 or so then drop back down and hover around 500 till it died. seemed like me giving it gas would flood it out and kill it. checked air filter and it's all good. I'm lost.

check your idle speed motor. clean it out with some gumcutter. clean your throttle body while your there.

it was a simple fix. pulled my fuel pump out and the hose I used to shorten my pump/sending unit came off some how. I went ahead and flared the tube then slid the hose on and clamped it as tight as the clamp would allow. thanks for the insight
