\015 Car isn't starting all the time. Has a New Fuel filter and fuel pump is putting out enough pressure. has a new battery. if when it soesn't start you spray ether into the air cleaner it will run and stay running. then about 4 or 5 times later and sometimes the next time it won't start. The starter turn over great. When we checked to see if any codes would come up it was empty. the car has 63,000 miles.\015\012\015\012\015\012\015\012My CTS will start fine. After a few minutes of driving after it heats up. the car has a Vapor lock action where the car shuts down. After it cool for 15 minutes it will start back up. The problem... no check engine light so no where to start.\015
Cam shaft sensor is bad. Cost me about $300 to fix.
Try changing the crankshaft sensor it has like a small nipple on it and i guess it wears out and it doesn't make contact i did it to mine and it workesd it started twice and then it did not start at all just cranked it cost about 30 dollars but its's pretty difficult to get to it's on the block on the driver's side by the exhaust.
