Thanks for the response. So I'm looking for an orange wire somewhere in the trunk? The car has been sitting for a while and only started being driven the last week. Since the fuel gauge is stuck at full should I just replace the sending unit? I'll also check with the meter. What will the meter tell me?blue78nova.....
You can check the resistance of the sending unit with a mulit-meter (if you have one) to see if it is working correctly. The wire you are looking for connects to the top of the tank and heads to the back of the car, goes into the trunk where it connects to the wiring harness, it should be and orange wire. There should also be a ground wire that connects the tank to the chassis. You should get a reading somewhere between 0 and 95 ohms on your meter between the orange wire and ground, based on how much fuel is in the tank. Let me know if you need more help.
Thanks! I'm new to chevys and this car is a lot newer than my 67 mustang. I started a thread about some stuff i need help working on but I haven't gotten any responses. I'm not sure if I posted it in the right spotNo problem, glad I can be of help!
I will post some pictures and a better explaination this weekend sometime as I will be working on my car. My Nova is a 74, I am assuming it would be pretty much the same as far as wire color and location.
