I need some fuel sending unit experts please
Help, I desperately need some help with my fuel gauge issues. I have read every thread that I could find on this topic in FABO and have a good working knowledge of the system but not a solution to my problem. The car has been in the process of being worked on for the past 15 years and was not driven until last week. All new fuel components from tank to fuel lines to filler tube to fuel pump.
My temperature gauge works perfectly. My fuel gauge and oil pressure gauge shows zero reading. I have the type of IVR that attaches to the fuel gauge only
New fuel sending unit installed complete with ground strap yesterday. Old unit bench tested fine after removal. With Key on, I am getting fluctuating voltage at the sending unit connector but it varies by timing and voltage. When grounding out fuel sending unit connector, the fuel needle at instrument panel goes to full. Double checked and I’m getting good ground at the cover plate of the fuel setting unit.
Removed the dash panel And soldered all pins to board (several of which were loose). Also cleaned all connections.
My main question is it possible for the IVR to function well enough for the temperature gauge to work, but not well enough for the fuel gauge? Will the fuel gauge function if the IVR is alternating voltages, but doing so in a way that it is outside of the function of the fuel gauge?
My plan at this point is to install a solid state IVR and disable the internal fuel gauge IVR. Is there anything else simple that could cause these issues that I can be missing?
