Exclamation Car cranks but won't fire, but eventually will

My 04 crossfire has just recently started with this problem, it will continue to crank even when I am not touching the key, but will not fire. Then once it fires it runs fine but the check engine light comes on. 1st time it happened I thought it was the key fob so I replaced the batteries. It has done it 2 times since and usually after I have driven even a short distance and shut it off then 10 min later it wont fire, but then does in a few mins. Any IDEAS???

Normall for the starter to stay engaged for a few seconds, but cranks and no fire is most likely the CPS (crank shaft sensor) search the threads, fairly cheap to get and easy to replace.

It will crank only as long as you turn the key on manual transmissions.

When you turn the key to start it, the car will keep cranking even when you let go of the key, this is normal & some crossfires do this. i have 2, one does this the other doesn't & it's totally normal. You can have the dealer fix this theres a TSB if it annoys you. It doesn't annoy me anymore.

As for not starting and long cranking times before starting, check the Fuel pump. As mine also had this problem & the Fuel pump needed to be replaced & now its starts right up.

Thumbs up Re: Car cranks but won't fire, but eventually will

Well I just ordered the Crankshaft Position Sensor for my car, I hope this fixes the problem. I'm a chick, think I can replace it myself? Thanks everyone for your help again!

So, what I'm hearing is ....get the part, and have a mechanic put it in?

If you can get the connector of the unit and have the tool to unscrew the little bolt you should be able to do it for yourself. You want an E8 socket.
If you have a mechanically inclined friend who owes you a favor, get him/her to do it for you.
Good luck.

Check valve in fuel pump gets stuck open. Fuel line loses pressure and vapor locks.

I sure hope I can live that down, someday. I know the financial cost is still hanging over my head - haven't replaced the truck yet.

So, don't be working on your car when going thru a divorce - THAT is the lesson.
