I replace the fuel pump two months ago i use to hear it come on now i dont I check fuses plus relay but the valve behind the throttle body no longer has fuel coming out. please help:icon_shrug::icon_shrug: I also replace fuel filter.

can any one tell me where the oil pressure switch for the fuel pump is located for a 1998 chevy blazer S-10 2wd.

Vehicle info would help and there are tons of threads on this issue..do a search!!

I merged your two posts together. Please try to keep things in the same spot.

To answer your second question, the oil pressure sensor is located on the back of the engine block near the distributor. However, it does not tie into the fuel pump at all on the newer trucks.

What brand of fuel pump did you install?
