Professional Lincoln

1989 lincoln town car fuel pump problem?

my husband recently had a car stereo/speakers/amp hooked up by a non professional . He cut some wires by the dash board and hooked the stereo through the cigarette lighter and now all of a sudden the car is not getting enough gas to run or stay started. does anyone know of a wiring diagram or if any of these wires have to do with the fuel pump? any ideas???? please help!!

double check the wires,,,it may be just a loose connection,,,thats if fuel wires run near the stereo,,,,then again,,,it may be something competely different,,,here is a list…..fuel injection?
any how……ENGINE STARTS BUT STOPS IMMEDIATLY..CAUSES….1)loose or dammage wire harness,,at coil or alternator…
2)intake manifold vacum leak.
3)insufficient fuel pressure.
4)fuel injection,,or engine control system malfuction.
……..ENGINE STALLS……………….1)idle speed incorrect,,,2)fuel filter clogged or water or dirt in fuel,,(when did u put gas in it),,,3)emissions system componets faulty,,,4)spark plugs,,check plug wires,5) vacume leak at intake or manifold,,check vacume hoses….6)fuel injectors or carb.
