Sounds like you may have damaged the electric fuel pump wire. Might have blown the fuel pump fuse. Hope this helps.

My 02 deville stalls


It may be tough to diagnose if you can't duplicate the complaint.
When it stalls you would need to know if you are loosing spark to the plugs or fuel to the injectors to proceed with any troubleshooting.
Could be anything from a faulty relay to the coil to the fuel pump.

93 Deville, 4.9L, 113k miles. I'm a decent mechanic (have replaced engines, heads, etc.). The latest problem is an intermittent stall. The first time it happened the car was driven for 10 mins then...


Now you can do the Fuel Pump

They seize up mechanically and fail
Electrically

Did you drive with a fuel pressure gauge,
taped to the windshield

Got a good fuel filter

Looking won't help you

Always do some type of testing,
before replacing anything

wow...BIG problem...I'd say you have a bad ECM - maybe you hooked it up "hot"? otherwise, check all grounds for secure connections.
Good Luck
