It is a 1998 4 cyclinder 2.2 motor Chevy S10 pickup. We put a new fuel pump on it and it still want start. We were told that if the oil sending unit is not working that it can throw the fuel pump off. Please help us!
MY S-10 IS LEAKING OIL. I WANT TO KNOW WHERE THE OIL SENDING UNIT IS.
I would not dismiss the possibility of the oil pressure switch being in the pump circuit...gm has used these on and off since the chevy vega. (remember them?)
It connects to the fuel pump it has 4 wires you shouldve got a replacement with it when you bought your fuel pump
Check for ignition spark first.If no spark the pcm will disable the fuel pump relay.
