Hi, I am having problems with my 1995 Jeep Cherokee 4.0L Country. When I turn the key to the run position the fuel pump doesn't run nor do the vent or radio, but the headlights, horn and wipers do. When I turn the key to start, the starter kicks in and starts normally, then dies instantly.

Tried the fuses and wiggled a lot of connectors. Any ideas?

 

Fuel pump ballast resistor, jump the two wires together see if it runs.

 

Could also be a relay. ASD relay possibly

 

Thanks guys, but got it figured out. The ignition switch unit had burned out and lost contact with one of the posts.
