Water Temp gauge issues
SO heres the skinny.... I have a inline adapter in my top hose that houses the coolant temp. for my gauge. ( the one that use to be on the water pump) Now its a one wire sensor, does the sensor need to be grounded to work? Before it was in the waterpump housing which "grounded" it. Im just fishing now cause I tried everything else.
Funny think is I rigged a plumbing pipe and tap the threads in it and tape doped the crap out of it and my sensor worked. But since I bought this new piece my gauge wont read. I replaced the thermostat and the sensor already.

So here's the skinny: That Sensor was the Coolant Temp Sensor which is used by the ECM to control fuel delivery. Later Years allowed you to see the signal in the Digital Display expressed as Temperature - and you must have one of those since those Models had the Sensor threaded into the Pump. Without it, you should have a steady Check Engine Light or maybe you took that out too? Anyway, it has or had a 5 volt reference (always Yellow) from the ECM and a Black Ground which is spliced into the Ground Circuit for the TPS and MAT. What you get on the Digital was through the CCM link. Without any of that, it doesn't run very well so it's hard to give you a solution for whatever you're trying to accomplish.
