Almost every s10 ive had or fixed with that problem turned out being a broken or severed wire in the harness.... Usually along the frame around the area of the driver's door, or within a foot or 2 back.... If i recall correctly, its a purple wire. And yea, it literally is you and every other s10 owner lol... Mine works, but my old beater was the same way

i had this VERY issue in my sonoma and turned out to be a bad sending unit. I went to the junkyard and go a sending unit and swapped out the sending unit part. My fuel pump was only 6 months old and im not dropping 200 plus for the whole assembly:D

purple wire is correct

this is a really common issue

if not a bad wiring connector somewhere then the sneding module unit is bad

new ones are $$$$$

but you could tyr a good used one if you can get one dirt cheap but its alot of labor to replace it in a non-pickup

so its your call as to what you want to gamble


if its that bad of a problem for you


personally since its not a pickup and is harder to drop the tank than on a pickup i would probably just live with it until the pump dies and warrants the cost its gonna be to buy a new module

which are around 250 to 350 bucks for these trucks

in which is one main reason why i wont own a 94 or newer truck

parts are too damn expensive for them

i stick with first gen where parts are free or basically free

and i have to agree with rage this is a common topic theres thousand sof posts on this issue if you search real quick then youll find hundreds of posts on this exact issue

also all over the internet, use a google search

have fun

i didnt ask for a smart ass remark, dont bother posting unless u helping tool.
Same can be said for you. Don't bother posting if you can't HELP yourself out and search first. Common sense says someone has had this problem before, genius, or should I say tool?

So, I'm a "tool" huh? Well, at least I know how to use the search function and rarely need to ask any questions because of it.
