1993 Oldsmobile Eighty-Eight Royale 3800 Vin L no start (again)
I was gonna say next to replace the oil pressure switch but another member all ready said that But my 8th digit in my VIN is a C. Buy I am glad you found your problem. Good luck.
One of the many reasons I am grateful for a New Mexico car.
I paid about ten bucks for mine but the price depends on it you have the light or a gauge for your oil. I have the light so it is cheaper. The price for the one if you have the gauge is about 25 bucks. I am pricing this from my local O'reillys for my 89 Olds Delta 88. So your price may be a little higher or lower. I am not for sure though.

I bought and installed the oil pressure sending unit, that stopped the oil leak. Next, I replaced the pump and guess what, it ran like a beast again. I also replaced the fuel filter so my car, mechanically, is brand new.
I am glad 2 hear that. I am at the point with mine I am gonna half 2 get rid of it or replace my engine and it isn't even at 150,000 yet. The oil leak I have is starting to get worse. I half to pull and clean off the oil on the spark plug in cylinder #5 every 300 to 400 miles. All of the other cylinders are in great shape except #5.
I am glad you figured it out!
I am having the same exact problem with my 1992 Oldsmobile 88.
Hopefully replacing the fuel pump will fix my problem.
The problem I am experiencing is the car will randomly stop getting fuel. It will work for a few days and then die randomly. I will sit for like 15 mins and it will turn right up.
I will keep you all updated.

I am wondering how hard was it to replace the fuel pump?
Is there any access holes in the truck anywhere so I dont have to drop the tank?
Also is there a fuel filter on our cars?
I have been hearing that there is not and then I hear there is one.
If so where is it located?
Thanks!

Pretty sure the tank has to be dropped. The fuel filter is usually under the backseat under the car, but some models they stick it where the passengers feet would be, where the floor pan slopes up. It'* hard to miss, it looks like a can in line.
