Fuel pump sender issues...

[syP]

Ive done this before on my old 97... fuel gauge starts acting weird... time to replace the sender


Being its a 97, it needs the 0-90ohm sender.. which is 97 and DOWN gms..

Went to the junkyard.. found a 97 GT, tested the sender, 0-90.. good.


installed it today.. Gauge goes INSTANTLY up to the top every time.

take it out, and notice it is doing the same thing the OEM sender was doing..

Sure it reads properly.. but since it pivots on a set "rivot", if it teeter-totters the wrong way, the little fingers on the sender do not hit the "washboard" thus making the reading 124ohms (exceeding 90ohms)

No matter what i do, when it sits IN the tank in "free fall", its always 124ohms. Sure i can get my fingers kinda down there and move it, but without my fingers, gravity pulls it back, and the fingers do not touch the washboard.

I tried for 3 hours to jimmy something under the sender to SLIGHTLY push pressure towards the washboard.. Lost it in the tank, lol.


My issue is, did i get another BUM sender? Do these "overstretch" easily?

Should i just try another junkyard one?


*also, i did have the pump outside the tank, on its side, connected... Put the sender MANUALLY to the half way mark, primed it, and the gauge read 1/2 full. So the gauge and everything is perfectly fine.. its just pivoting too much and the fingers are not making contact

I might have another sender around somewhere, but I would just bend the little fingers down and make it work... hopefully that is possible. I know I have seen the senders missing some of the fingers altogether.

yea i tried that.. then it started making a really loud scraping noise and the senver kinda got stuck.. i tried everything.

Im not 100% sure of what portion you want of what i texted you in the pic. sooo i could get the whole thing to you i guess and just take what you need and get the rest back to me?

ill take a picture a little later of what i need.. i have 2 sitting in my garage right now lol

but its like this..

see the 2 purple wires? cut them in the center... and give me from where you cut, and DOWN.. the sender, arm.. etc.. i do NOT need the canister, or the above wiring/hoses.

Will that work if i still use my 97 sending unit? That piece just has the little fingers, thats it.. reuse the stock white clip, float.. everything else..

What is the part that determines what the correct OHMs is? This little peice? or the physical washboard on the white clip-in piece?

HOW FUNNY, I had a guy down the street change out that after my last post and you told me what to change Syp, and my guage didnt work at all. The sender was only like 15 bucks so I cut my loss and put the stock one back in. Now Im just planning to change out the pump with in the next month or so.

when it happened 3 years ago on my 97 GTP, it fixed the problem
