The first gauge not working is the temp gauge, there is a mechanical gauge wired in its place so not really worried about that but is this where the sensor goes? Because there is a sensor connector here and a hole where a sensor would fit. With this type of plug the second gauge is my fuel gauge. The previous owner changed the fuel pump so i guess he messed something up while doing that. The needle just sits all the way at the top of the gauge point STRAIGHT up, it doesnt move at all. To top it all off the gauges dont even light up. I replaced all my fuses, the check engine, brake light etc. all work but the gauges do light up. Any help is appreciated.

found out it IS a temp sensor, but from what I read it not for the gauge, its for the ecu.

I also found another overheating problem, if I have no sensor there, pressure and coolant are escaping out. Wow



EDIT: could be wrong, the temp sensor I was looking at is in front of the thermostat, the one I found is behind on the intake manifold

Is the sensor a throttle position sensor? I found a picture off google that showed the positions of a few sensors

If you have an ECM, you will have a sensor to give it engine temp data... there is also a sender that controls your temp gauge.

A throttle position sensor is going to be on the throttle body. It measures movement of the throttle plate. That is NOT a TPS. Since it has two wires, I make it out to be the ECM temp sensor.

Re► Fuel gage. ▬ It sounds like the sender, however to verify, disconnect the sender wire to the gage.

If the gage continues towards FULL the sender is the problem.

Re► No gage lights. ▬ If they failed simultaneously and the other cockpit illumination works, radio illumination, HVAC illumination, etcetera, the problem most likely is a cracked trace (difficult to see) inside the dash.

wow i should've known that one. I still havent found out what that lug is for, Been busy trying to bypass the vats.

crazy, i was going through my wiring and noticed the inst lps wire was clipped and twisted back together. I took a hotwire and touched it to that one to see if that could be the culprit. The gauge lights cut on when I did this.

I was so excited i called my girl out to look while I touched the wire to the inst lps wire. I had her move the dimmer switch but for some reason it would dim the outside lights and not the gauge lights.

I took the wire off and pulled the dimmer switch to turn on my headlights and bam, everything, including my gauge lights popped on. The dimmer works and everything. i guess jumping the wire with a hotwire for a few seconds got it juiced up and working again

That's got me scratching my head... I suspect that the spot where it was twisted back together was probably a poor connection. I'd secure that connection and either solder it or wire-nut it to avoid future problems.

Ya im going to pop a connector over it today
