The oil pressure sender?

It's on the side of the block. Pretty easy to swap out.

As far as starting fluid, just open the Throttle and spray some in while turning it over. See if it fires.

OPSU is by the oil filter. Once you have the new one, its easy to find the identical part on your block.

well i went to get the car today & found out the fuel pump has been tested & proven to be bad, there is supposedly voltage running to it, so i bought a new fp. also is the OPSU a little metal housing with a plastic sensor female connector? when i called autozone they looked it right up for $6 but when i went there they could only find an "oil pressure switch" is this it?

[robertisaar]

if it has the dummy light, then yes the switch is correct, if it was a full guage package, then a sensor would make sense

Sounds like the one they have is for cars that do not have an oil pressure gauge but rather just the idiot light.

If you have an oil pressure gauge you need the sending unit for that. I think it was $20-30 when I replaced mine. Autozone should be able to look it up.
