Oil Pressure Sender

[Volucris]

Today my oil pressure peggged at 80 and stayed there. It also does it when the key is on, but the engine is off. I'm pretty sure I have a bad pressure sender, but I thought I would check here to see if it might be anyting else. Any ideas? And how the heck do you get to that thing?

It is in the hardest place to get to on the engine.

Here's a good place to start: http://www.gm-trucks.com/forums/topic/169782-attention-anyone-with-oil-pressure-issues/

 

I worked for about an hour on mine, before giving up & taking it to the mechanic. I'm not afraid to do light wrenching, but I didn't feel like messing up the UIM when I need the truck every day.

 

Good Luck,

Easiest way to get it is to pull the intake manifold. Have a gauge sweep done too to make sure it's not the stepper for oil psi in the cluster.

Thanks - Pull the intake manifold for a pressure sender? The last time I changed one was on a Ford 289 for a '66 mustag. Much much easier. Looks like the garage is going to make a little money.

I was able to replace mine without pulling the intake. It takes pretty small hands and a good bit of dexterity, but you can do it.
