The fuel gauge was working intermittently with the old tank and sending unit, and the gauge would go almost all the way to full when I momentarily ground the sending unit wire. I have installed an Aeromotive fuel tank with efi pump and new sending unit along with Sniper efi and the gauge is dead.
I have verified good ground and also have the 5 volt reading at the tank wire. I verified the ohms reading on the new tank before installing and that’s good. Re-checked sending unit after install and was at 32 ohms at about 1/2 tank so that’s still working.
My question is if you have the 5 volt at the sender wire doesn’t that suggest that the gauge should be working as the voltage goes through the gauge correct??? Or am I missing something here.
I am really scratching my head and any help is greatly appreciated
