    Hot start, Long crank

    I have a 2005 Dodge magnum rt 12/04 build date, kn drop in filter, cat back exhaust.
    My problem is that if I try to start the car when hot it cranks for about 45-60 seconds then starts and runs fine. I have installed a new fuel pump thinking that was my problem with no success. I think that maybe there is a temperature sensor that might be going bad any advice would be appreciated.

    Bad fuel filter?
    Maybe the ECM is going bad and the heat makes it not work? Heat and circuit boards don't do very well together.

    Oh, and don't crank the car for 45 seconds straight. You'll burn up the starter.

    There are no fuel filters on these cars they have a strainer on the bottom of the fuel pump

    I have had the same issue from time to time. I find it minor issue, as long as it starts. So far so good.

    Yeah I myself don't care that much but the wife drives the car mostly now and she is afraid it might not start one time and with no check engine light the stealership wants $ 90 just to look at it even if those idiots at my dealership can't find a problem

    I remembering reading about this somewhere. I believe the crank or cam sensor was the culprit. Please correct me if I'm wrong.

    Yezz sir, the crank postion sensor. Good call bud


    They run under 30 bucks and it's located on the passenger side behind the starter. You'll need to remove the starter to install it ( well it's 10X easier if you do ). If your handy with tools, it'll take you 20 minutes to change.

    I've had this on this car and others, its not so much that the sensor is bad just how its "timed" sometimes. THe cam and crank sensors work together, working of timed refrences usually. Just sometimes when the motor is shut off the slot that the sensor uses for a reference is sometimes just a lil off from where it likes to be. So the car sometimes had to crank longer to get "re-referenced" so the proper timing positions line up, the sensor become synced and the car starts. Just sumtin that happens now and then. Usually not a big deal.

    Very good point. It could be your cam chain tensioner is wore out too.
