Question about 2004 Dodge Intrepid
Car cranks over but wont start sometimes, usually when it sits for a hour or more. But when you try to crank it over and wont start if you turn the key completly off and turn over again it seems to start up fine. Runs fine down the road once its running.I get codes p0645, p0508, p0688 on the dash if i use the key on off three times check.
crank sensor or fuel pump call A MOBILE MECHANIC as its not the sort of thing thats easly diagnosed from a description sorry

Manifold Absolute Pressure/Barometric Pressure Circuit High Input
MAP sensor input above maximum acceptable voltage.
Intake Air Temperature Circuit High Input
Intake air (charge) temperature sensor input above the maximum acceptable voltage.
Idle Air Control Motor Circuit Low
Idle Air Control Motor Circuit input below acceptable current.
THESE DIFNITIONS ARE FROM THE FACTORY REPAIR MANUAL, LOOKS LIKE YOU MAY HAVE A WIRING HARNESS PROBLEM OR DISCONNECTED COMPONENTS, CHECK THE IAT AND MAP SENSOR AN MAKE SURE THEY ARE CONNECTED.

i had the same problem. as soon as i would put it in gear, it would just stop, almost like somebody just turned off the ignition. if that is the same problem your having, or if not.. check the neutral safety switch or for loose wires or plugs. sometimes the vibration will jar them loose and cause the neutral safety switch to engage, if not. have your power control mod tested.. hope that helps your problem

Is the pressure in the fuel system not holding? Fuel pump may be failing or the filter may be bad. Sounds like you're pumping the fuel system back up to pressure before the truck will start. Like when a fuel-injected car runs outta gas and you have to prime the system before it'll start again.

if it shuts off after running for a while and will not restart for about 10 min,a bad crank sensor will cause this. abad crank sensor will make car shut off and not restart for about 10 min. put a scanner on to make sure. a check engine light does not allways come on. if you do not have a scanner, any auto parts store will scan it for free.
