I left some important info out when explaining my problem. i have an 04 touring auto. it has 38k on it, i bought it used at 19. it has a pop charger that i have recently clean out.

my car wont turn on occassionally. maybe every 3 out of 5 times, when i turn the key the car keeps on cranking and cranking but wont turn over.after repeating this maybe 5-6 times the car will finally come to life. i tried finding the problem bu no error codes show. im going to change the spark plugs today and see if this correct problems. or do you think it might be an 02 sensor or something?

since the mileage is getting up there(40k) is there any recommended maintenance that i should be doing? fuel filters? transmission service?

i appreciate your suggestions!!!

 

Did this problem start to occur after you cleaned the pop charger and if so how did you clean your pop charger?
