My wife car having this weird problem starting and actually firing up,acts like it has a dead battery because it will drag while cranking it up but will keep doing that untill it will fire up then it will crank and crank but wont fire right up but it will eventually will start? I put the battery on the charger over night and still drags but battery good? Im lost any input please guys

jump the battery and see if the problem persists. i could still be a bad battery even if the charger says it's good.
the next thing could be a bad starter (hope not, bc they are a pain to replace).

what's the mileage on the car?

Ok ill try that and yes i know about the starter beause we replaced it last year lol such a pain! But when i was looking and checking wires i noticed these wires where im pointing at while car running when i lift up on them the car shuts off every time????? Its on the passenger side between intake and valve covers?

Are those your spark plug wires? If so, there's your problem. You most likely have a short or they are not attached to the coil properly.

Are they?? Im not sure what those wires are for,i would like to know,haven't had time off from work yet to check it out

One of those leads may be to the coil. The plug wires are under the dust shield routed behind the cam.
