Cadillac Repair: 98 Deville Computer problem, volt ohm meter, digital volt ohm meter

Question
Hi,

I just purchased a 98 Deville.  It has some sort of electrical problem caused by the heater core leaking.  The car will crank but not turn over.  The repair shop is telling me the computers are not communicating.  Some of the wiring on the passenger side floor were damaged by the heater core leak, but they were replaced and the car still will not start.  Also, the fuel gauge is not reading and the a/c does not work - Can you offer some advice?

Answer
You are going to need a DIGITAL VOLT/OHM METER which you can purchase at Wal-Mart for $20.00 or at any auto parts store and you will need the assistance of:
