Engine/Transmission (1998.5 - 2002) no tach, oil, or temp

[SCollett]

I was driving home last night and I looked down and the tach was sitting at zero. Then I noticed no oil pressure or water temp. The engine light is not on, it seems to have the same horse power as before. Maybe a fuse or sensor. Its a 98. 5 3500 24v 5sp 4x4 with edge comp, dd3, 4inch exhaust, afe, gauges.





thank you

Have you checked for codes? Could be the crank position sensor. But the Oil pressure and Water temp could be controlled by the ECM. Just a thought

check the 3 wiring harnesses on your ECM.



Mine did the same thing, my middle harness was not fully plugged in.
