Hi James,

It could be your key. Try your spare and see if it still does it. Otherwise, do a search and you'll find info. Could be ignition switch too.

Good luck!

OOOPS..SORRY ,JUST REALIZED IT WAS AN OLD POST....!!!!!!
Your fault Blue eagle
Dealer said no error codes on diagnostics and yet they found out a burnt out pump relay!Dont make any sense!This would be bring up a FUEL INJ error!
Since the dealer is not being cooperative,you need to find a good independent or another dealer.Someone that can hook a diagnostic equipment that reads/records live data.Try to start the car and when it doesnt start ,you should have the error information recorded.
When it doesnt start,do you see any smoke from the exhausts?Does the engine turn over when it doesnt start?
