If it starts after turning the key on and off several times, it may likely be a faulty electrical ignition switch assembly.

sometimes it won't start until we put starting fluid in the throttle body we was told to replace the fuel pump cause it should have 60 lbs of pressure to start but it only has 50-55 so were changing that, we had the ignition switch checked at the dealer and they said it was good. THANKS FOR YOUR HELP!!!!! :)
