I recently purchased a 98 s10 blazer 4x4. I had to replace the fuel pump first thing. Due to money issues I ordered a replacement pump through an online dealer. The arrived fast and was an exact factory model new and all. The issue came to the wiring connector it came with. It had the same number of wires as the factory plug but they were different colors. I need a wiring diagram of then factory setup so I can deduce which wire i may have crossed. The pump works great just the level indicator doesn't. Any help would be greatly appreciated.

 

Is your gas gauge reading empty all the time or over full? I just recently fixed mine myself and can explain to you the process if you need me to, it's very very easy if you're a hands-on kind of person.

 

Id like to know the answer to this. Got a 02 blazer 4x4 that always reads below E. I have to count my mileage to not run out of gas.

 

I`d like to know how you did the easy fix on the snding unit,Mine all sudden wouldnt go below 3/4 then within 2 weeks it goes all the way past full and pegs out there no matter what.I dropped the tank when it 1st started acting up and cleaned up connectors and bent tabs down etc but no differance.
2nd Issue is when my pump went out i bought Ac delco and 6 months later returned it and got another ac delco then 8 months later threw it at the Ahole at advance since there parts never work and went and bought a delphi from autozone and once again 8 months later had to drop the tank and return it.This time i said screw all this talk about them pumps they suck,even did it 3 times on my brothers 2000 silverado.So got the Airtex and thats been 4 years ago and 94K miles.But the sending unit mounts on differantly then all the others so the 2 i have from all the pumps i went thru wont snap on the airtex housing.
Been driven by doin every 340 miles i fill up,2000 chevy blazer 2 door LS model.Gonna drop the tank and either swap out the control board if possible and if not then i`m just gonna screw the replacement onto the housing,hell both sending units only have 6 and 8 months on them.

 

hi I replaced the fuel pump, and put in new lines and a new sender/ floater but when I put a few gallons of fuel it will say I have a half a tank up. Then it will drop to e and the light comes on. If I accelerate the fuel gauge will go up, so I'm not sure where the problem lies. So I need a new tank?
