This happens every now and then, i will go to start the car and its starts cranking i let go of the key and it keeps going. Cranks between 10 and 15 seconds then finally starts. Runs rough for a little bit but my afrs dip between 9.5 an 10.5 and idle. Drive the car for a mile or so and its fine. Any ideas would be great. Thanx-Gary

 

does it happen after you fill up? if so unplug the evap solenoid line to the evap solenoid

 

Yea only time it does this. Whats the fix?? I dont want to unplug anything, id prefer to fix it the rite way

 

Under warranty? Take it in and complain of an extended crank.

 

evap purge valve is hung open same thing happend to mine thats why i sait pull the line off the evap vave next time u fill it upand see if it helps and as far as a extented crank at the dealerships good luck with that

 

Had this issue, threw a code (I think it was P0496 Evap High Purge Flow Fault) went to the dealer and was fixed under warranty. Just wait you will probably get a random CEL in a couple days and take it in.

 

Did you unplug the battery prior to this happening?
The computer seems to need to run a quick check after it's been off and it seems to crank for about 10 seconds before it starts.

 

Take it to the dealer tell them whats happening.

 

The car is supposed to crank on it own after letting the key go. Its listed in the manual that it has a computer assisted start or something like that and it will only stop if the car will not start after a while. I don't have the manual in front of me so I cant be more specific.

As far as the problem goes I cant help.

 

Cool thanx i have had the p0496 high purge flow code on an off for about a month now. I unplugged the solenoid to see if it would help, bit either way it still does it. Ill take it in to the dealer when i get some free time

 

This just started happening to mine. The last two fill-ups has it running rough on the first start up. Rev it a few times and it's fine. Same DTC - P0496. Anyone know if this is covered under the extended powertrain warranty? I'm at 41K already on my '08.

 

If not, I believe it's a cheap part and extremely easy to get to.
