92 3.1 v6. Problem started earlier today when I hit a bump an car suddenly died. pulled to side of road and tried to start but just cranks..I noticed that my check engine light wasn't coming on and then off like it normally does when I turn the key to on. Also fuel pumo wasnt coming on. so checked the fuse and it was blown. so popped another one in and same thing again and again,. Also disconnected the plug at the back of the fuel pumo and still blows the fuse. Any help were to start? my battery cable was a bit loose . Could i have shorted my ecm or something? The security light still comes on and goes off so that is okay.,

 

Check the wiring on the relay plugs on the fuel pump relay and maf relays, over time the insulation can slide down exposing the bare wire and causing a short that will blow the 20amp fuse. Could also mean a bad fuel pump. I also had a problem in the wiring harness behind the engine where it goes into the trans tunnel..years of rubbing caused and open wire. I hope this help find your issue.

 

To facilitate tracing a dead short that instantly blows fusees, wire an old headlight bulb in place of the fuse. I soldered wire to each side of a blown fuse, then attached wires to the bulb.

Open both doors and depress the dome light switches to open (shut light). Make sure everything on the circuit is turned off.

When you find/correct the short, the light will go out.
