I put in a GReddy EGT and it was working fine. It was moving and loving life it seemed. One day I cranked my car and noticed no movement whatsoever form the gauge. This is not good when breaking in a new turbo motor. the lights are on, but nobody's home, as the needle just rests below the 300 minimum temperature... Weird.

Anyone else have problems.

 

Perhaps it became disconnected from power?

 

Recheck all wiring/grounds/etc...good chance that a wire may have melted or became loose.
This has happened to me before.

Definitely an electrical problem. One of your wires probably popped loose. Either that or the sensor got dislodged from the manifold somehow (most likely this isn't it).

 

Still in hte manifold without problems, chcked the connection under the hood, nice n tight... Probab;y gunna run continuity tests on it this weekend...
