1987 S-10 Chevy Blazer Fuel Problems HELP!!!

[nosmallchange]

My 1987 Fuel injected Chevy Blazer S-10 2.8 V6 4WD just up and didn't start one day. I primed it and it ran with the prime, so I figured it was the fuel pump. After dropping the tank and replacing the pump, it still didnt work, so I did some looking and the 10 amp ECMB fuse keeps blowing when I turn on the key. I tried to change the Fuel Pump Relay, I think I changed the right one, and it still blew fuses. ANY IDEAS??
Thanks.

i had that same problem with my blazer and i got under my car and found out that the exhaust pipe under the car right by the transmission burned my oil pressure wires and some other hot wires and i just cut the wires short so where they dont touch and now i am back up and running again. it happened to me the other day...

The problem is your oil sending unit. My brother had the same truck and the same problem. Simple quick fix is unplug the wire to the oil sending unit and replace the fuse. My brother did this to his and it fired right up.
