Hey guys have and oil pressure gauge problem. I purchased my first diesel truck a few minths ago and I know what you are saying "what took you so long?" When I pruchased it I noticed when I accelerated the oil pressure gauge would stock flickering and jumping around and the check gauges light would come on. I ded check the oil level and oil pressure and that is all good. 60psi warm and cruising. It only happens when I accelerate. Once I am up to speed and cruising it stops doing it. It sounds electrical to me. I had a gas suburban that did this every once in a while but it would do that any time. Like I said I am new to the diesel scene so everything is a little different. I don't even know where the oil pressure sensor is to check the wires or replace it. Any help would be appreciated.

the sending unit is in the same place as on your old gasser....it is larger because it is also the switch for the fuel lift pump....

 

clean all the grounds near the dash. as ive said before these trucks act wierd when they dont have clean eletrical connections.

 

Thanx For input fellas. I will take a stab at both of those areas sometime in my insane busy future. I will keep in touch

 

look for crack in the caseing and the plugs
