bought the truck in july an sending unit didnt work. i got one from the dealership i worked at. put it in an worked great. month later pump itself went out. got a aftermarket pump put in an sending unit didnt work so i swapped it out an samething tried once more an the same thing. bought a haynes manual last night an cant find the wiring diagram for the sending unit anywhere. i kno its hooked up right ive had fuel issues with 4 other vehicles in the past but this one stummped me. any suggestions??

 

I believe there is a factory manual for our truck in the faq. I had mine go on me, replaced it and had no problems since. It is possible to have a short in the wiring that is killing your pump. Is your tank and fuel filter clean?

 

yeah they are

 

So your having your fuel pump and sending unit dying? That is really weird. It sounds to me like a wiring issue. Bad ground or connection somewhere? What fuel do you run in your truck?

 

the pump works perfect the sending unit wont work an i swapped the aftermarket pump out 3 times with a different one

 

Personally, I think you have a break in the line somewhere. Did you do a continuity check?

 

i got feed up with it an stopped messin with it but i really wanna know how much gas i have lol. the gas light is always on an reads 1/8th no matter how much gas i put in

 

Has it always shown 1/8th? and do you know for sure if your floater fell off or not in the tank? If not I would agree, you have a electrical issue.

 

Did you do a continuity check?

 

when i got the sending unit from the dodge dealership worked great month later that pump went out so i got a aftermarket one i pulled each pump out to return an everything was there (ive exchanged the aftermarket pump 3 times)
