Fiero Fuel Sensor Rewire ? (Page 1/1)
Tom9092 DEC 24, 11:10 AM
Has anyone tried rewiring the resistance block with nichrome wire?

Several of the strands are broken and the gas gauge registers full right (no continuity).

I know the Fiero Store sells a new fuel sensor assembly, but I bought the car to work on, not just replace parts (OK, I'm cheap also).

I have the specs for the resistance required and can determine the amount of wire required; I just want to know if anyone else has tried this.

Thanks

The only option I’ve found …aside from buying Fiero Store expensive sender … is possibly buying a sender for another GM unit and swapping the resistor as almost all of the early GM units are 90 ohms.

NAPA offers new Fuel Level Sensor contacts, P/N GM64. Will check with them 27 Dec to see if it will work.

Apparently, I'm not the only one who refuels based on odometer readings, lol. My gauge moves a little but stays at the full end. If those Napa parts work, it will be a good solution to a common issue with a lot of GM cars.

i use my tripometer as my fuel gauge. refill at about 150 just in case i was a little bit very heavy footed that tank lol

Maybe this will help.

Gm uses 2 or more sender versions over just Fiero years.

Above won't fit some senders.
Like mine w/ 2 piece shell w/ bend ears at 3 points keeping them close.

And won't help any w/ broken nichrome. I've never seen anyone replacing this part. Only a tread in archives now saying how to clean and other minor repairs.

GM64 won't work. Talked to local NAPA store and they (& I) decided it wasn't what I needed.

Next stop - Get 84-88 GM fuel sensor from local junk yard. Swap and see what happens. If no go, rewire junk sensor block with nichrome wire.

Will post results, but I'm not fast. I'm not slow either, more like half-fast.
