You can do a gauge test. Just press the trip/reset button, hold it down, and turn the ignition on. (don't start the engine.) The test will then start, all lights in the dash will come on, and all gauges will go thru a full sweep. If that works properly, then the problem isn't the cluster. PCM tells the cluster what to display, including oil pressure...... Heck, even the friggin gas gauge goes thru the pcm.......

The whole 'oil pressure drops to zero at idle, but, giving it even a tiny bit of gas bring it back up to normal' is a fairly standard failure mode for the oil pressure sensor.

 

Wow! thanks man, I appreciate the info

 

So I guess I'm gonna have to buy a oil pressure sender/ switch to fix my problem than

 

Yep, they aren't hideously expensive at least. Fun to get to though.....

 

Ok my knowledgeable friend where might I find the sending unit on my motor I got one ordered from Rockauto.

 

I've been putting off cleaning my disty cap for a while just because of this. Why make it easy like the LA disty where you can snap on the cap.... nope screws.

Hell its a chore and a half to get the air cleaner on and I dont even have the rubber behind the hood on. Or people who put a spacer on the intake for their tunes... why did they make it so hard

 

Back of the motor, just to the passenger side of the distributor.

Because engineers HATE mechanics. That's the only conclusion I can come to.

Thanks for all the help my friend!

 

That would explain why my cowl has a giant hole in it. Has rtv on the inside but m like they put a panel there but I don't have the panel. Thought it was for a big oval air intake

 

I don't think it's personal towards mechanics. I think engineers enjoy creating planned obsolescence so that the older trucks get so frustrating to work on that it forces you to purchase a new one to keep themselves employed.
