I have a 2002 chysler 300m 3.5 when I drive it to the store when I come out it won't start till I put scanner on then turn key to accessories wait for engine light flashes then goes solid it will start

 

Do you get any codes off the scanner?

 

no codes

 

the scanner has to be connect but don't have erase just has to be connected what for check engine light to stop flashing then it will shaft

 

that has nothing to do with anything the light flashing when the car is not running is normal just like the oil pressure lite is on all because the engine is not running those lights will come on and do there thing.
