    Default 97 chevy 2500, will start sometimes

    really weird, turn key and will sometimes get all dash lights to come and truck will start, the next time I turn the key only half of dash lights will come on and truck will crank over but wont fire. replaced positive cable to alternator check all other positive cables in good shape, installed a new battery... the strangest thing off all is if we jack up front of truck will work every time, or if we put a battery charger to it will go every time..... thinking maybe we need to redo the ground, or a fluid sensor...

    Sounds like a groud issue to me. Make sure the ground wire from the engine to the body is good as well. In some rare cases ive seen where if you have a tilt steering wheel it can cause the wires in the piviot part of the colum to break if its old and was never really moved untill recently. Probably not the issue but i've seen it happen a couple times causig weird things like that. Other than those it's possable that your ignition switch is bad too. Not the key/tumbler part but the actrual electronic part of it behind the tumble piece.

    Hope this helps a little good luck!
