Fuel Gauge Question need help
This is for a 1989 YJ 2.5 with 15 gal tank fuel injected.
My gas gauge had never worked since I bought the jeep. I always assumed that it was the sender unit but was not that worried about it. Well last month my fuel pump died. I went through the usual test everything first and finally decided to pull the tank. I bench tested the pump and no worky. Now since I had the whole thing out and apart I cleaned the sender unit and it had a smooth 1 ohm empty to 88 ohm full just as it is supposed to. So I plugged it back in and ran the float up and down. The gauge still pegs high and flutters around a little, but does not read even remotely correct.
I measured the voltage (tan wire to ground) and it only reads 7.8 to 8.1 volts DC at the supply to the unit. I am thinking that this is supposed to be 12v and there is a fault either in the gauge or intermittent wire fault somewhere.
Can someone with a working gas gauge pull the plug at their fuel pump and verify the voltage at the pump connector for the sender unit?
Anyone else have a similar problem?
Thanks in advance.
