2002 Durango won't crank
10

Asked by Grimieb Jun 28, 2016 at 01:00 PM about the 2002 Dodge Durango SLT 4WD

Question type: Maintenance & Repair

I have a 2002 Dodge Durango 4.7 that
won't crank, particularly when it's hot. All
power turns on, but it won't actually start
for about an hour. It seems to happen more
when it's hot out, but I can't find any
correlating factors with it. Runs fine &
always starts up eventually, just takes
awhile. I also have other odd electrical
issues such as the speedometer/odometer
not working, ABS light on, back some light
not turning off (I had to remove it), etc.
could this be an issue with the fuse box
under the hood or certain fuses? I'm not
extremely mechanically inclined could it's
possible I'm missing something big.

It makes no sound when the keys turned. I'll get the codes ran.

Clean your map/mav sensor. It's located somewhere on your throttle body/air intake. That little diode measures the amount of O2 in the air and adjusts the amount of fuel to send to the injectors. If it gets just a little dirty it throws off the whole system. Squirt it once or twice with engine cleaner. Be careful though. It's delicate and expensive. It'll improve your mpg too..
