2000 Monte Carlo SS, intermittent starting issues, turn key and all lights up but nothing then wait and it starts. I have posted on this prior and you all came up with either a ign switch ( I replaced twice) crank relay next to fuses under hood (replaced) then Crank Sensor and I had the Dealer fix since it looked like a pain to replace. Well, they diagnosed it as a crank sensor and it worked for a week and then SAME THING. I waited a day to try again and nothing. I had it towed to the Dealer and they cant duplicate. This is nuts, it starts every time for them. They have their best guy on it. Im thinking bad crank sensor but they don't want to replace it again. Maybe a neutral switch or any other thoughts I can offer the Dealer to look into? HELP!
