As always, I'm loathe to bring my car in to the mechanic (do most work myself). So, the gage indicates 0 oil pressure sometimes (car used to be solid 30 or 60 psi). What are the best and easiest ways to figure out if its a sensor/gage problem vs. oil pump problem.

Thanks, Dave '91 T/A, '91 GTA, '01 T/A WS6

 

I had the same problem, and all it was, was the oil sender that is bolted on the back of the manifold. It looks like a small fuel filter with an electrical connector. Or it could be the one that is right above your oil filter. I changed both of mine, they are inexpensive. Hopefully that is all that is wrong.

 

YUP, i'll bet $$money$$ that its your oil sending unit.

mine was out for a while and would constantly drop to '0' when i hit the brakes to a complete stop. replaced it, and now i'm gold.

 

hey brian is that an oil sending unit on the bac kof the manifold or it it the oxygen sensor

Easiest way is to verify the pressure with a mechanical oil pressure gauge. Your sending unit should be above your oil filter.

The oil sending unit that is on the rear manifold,or some people call it an INTAKE. It is right next to the distributor on the drivers side. Your oxygen sensor is screwed into your drivers side exhaust manifold.

Thanks guys, I'll replace the oil sending unit over the weekend. My symptoms are identical to j166a99.

Thanks, Dave

 

Actually, the oil pressure sender is in the block, not the intake manifold.
