Command Start

[BMHPARTS]

I JUST GOT A 1996 JEEP GRAND CHEROKEE THAT CAME FROM NORTH DAKOTA. IT HAS A COMMAND START 3000 ON IT. I WAS TOLD IT IS TEMPERATURE SENSITIVE AND STARTS THE CAR WHEN IT GETS TOO COLD? THE PROBLEM I HAVE IS THE STARTER STAYS ENGAGED UNTIL YOU PULL THE BATT CABLE OR STARTER RELAY. I UN-PLUGGED THE COMMAND START AND THE PROBLEM STOPPED. I REMOVED THE WHOLE UNIT AND NOW IT CRANKS OVER WITH THE KEY JUST LIKE IT SHOULD, BUT NOW WON'T START. IT HAS NO SPARK, THE GAUGES DON'T WORK AND THE FUEL PUMP DOESN'T RUN.
AM LOOKING FOR ANY HELP OR MAYBE A SCHEMATIC THAT WOULD HELP ME FIGURE THIS THING OUT.
THANKS
