my grand prix will start on occasion and then it wont why
My 2001 Pontiac will start and then it won't....it will not even turnover....after awhile it will
start...does not matter if engine is cold or hot....Why?
there is a layer of corrosion on the end of the 1/0awg Black battery cable...wirebrush the end of the cable and the spot that it bolts to...assure that your battery is newer than five years old....or get a NEW battery...the 1/0 connection to the engine block (usually near the alternator) needs to be free and clear of corrosion and happy with 300 cold cranking amps~
could be a bad battery connection , bad neutral safety switch, or the sucurity system trying to go bad , does it do it with all the keys that fit the car ?
strange phenomenon...that...your ECU is dependent on steady 12.5 volts with steady unwavering ground....withe every start, the startermotor insists on HIGH amperage, 300 cold cranking amps is minimal...but a blue flame and spark ensues because the electrical connection is of dis-similar metals...at those temps one metal liquifies into the other creating a layer of corrosion....wirebrush this unwanted "semiconductor" layer off the ground connection for a correct ECU operation and NO troubles anymore...god bless~
