HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, did you use new or used parts when replacing the sending unit and fuel data center

And I need to get the engine size as well as the last 8 of the vin number to pull schematics

As yours is an older one I would like you to try something first, either get a small jumper wire with alligator clips on both ends or make one up, then at you fuel tank attach one end to a clean spot on the tank and the other end on a clean spot on the frame or body of the car and try that. I'll check back tomorrow what happens.
