Question about 1994 Chevrolet Lumina
It blows fuse instantly almost i heard it could be a bad oil sending unit?
Oil pressure switch is the last item that could cause this. That system operates on a ground, a short would give you an erroneous gauge reading. You, or a shop, will need to trace wiring on the power side of the computer. a ground there (or in the computer itself) will cause the fuse to blow. a short on the sensor side will give you bad information to the computer, and cause running issues but generally not cause a fuse to blow.
In order to do a proper diagnosis you will need a good volt/ohmeter, a good schematic and a lot of patience.
