haveing starting problems

car used to cut off alot while driveing. now wont even start. replaced all fuses, body controle module, security module, fuel pump, any ideas would be helpful. Thanks

Engine type and size, mileage.

3.4 fuel injected 78,000

could be your fuel pump have you ever changed it? if not i'd get it tested.if your check engine light is on take it to autozone,or advanced..could be your cps also...

put in ignition switch and fixed problem. now i have lost all power inside the car such as, windows, automatic lights, gauges,and stereo. it worked for a day then it went out.
