Isspro ev2 pyro/egt gauge staying at 0 now. Has power.

[Tsbourne09]

My egt gauge is getting power but its staying at 0 it was going to 500 crusing at low speeds but when i gave it more fuel it drops to 0. I did hit 2000 one time yesterday when i was trying out my new fuel pump mods. It all started today when i rocketed up to the upper teens then the gauge bounced from 16 or 1800 to 0. now it does not read at all... Its an isspro ev2 pyro. You think the sender/reader/probe in my manifold is at fault??

Check your grounds.

Also, is there slack in the wire from the firewall to the probe? Reason I ask is the engine twisting from torque needs a little bit extra wire so it doesn't pull them loose.

sounds like a wiring problem, doubtful the probe is bad, but you could have trashed it at 1800 degrees lol, pull it and check it with a propane torch
