I think I did that but with the feed wire still in the solenoid. Behind the passeger seat I found the connectors of the fuel pummp .i attached the multimeter and when I start it I got 0 voltage

I fixed already those wires that were rusty,, now I removed the maf sensor and I sprayed starting fluid and it turned on right away and smooth,, but once again. I check all the relays with the multimeter and apparently they are fine and I still have no voltage at fuel pump. Please help guys I will appreciate so much.

Newzed do you know where to get the relays for the fuel pump

Newzed I'm gonna try that with the oil pressure sender disconnected. And I disconnected the fuel pump conectors behind passenger seat,i attached a multimeter and I got no voltage when key on and not even when cranking.. Now I'm fixing some wires.im soldering those wires That go to the fusible links they are rusted And corrorroed

Thanks bro
