2001 dodge durango wont start

How cold is it there and how many miles are on it?

my durango has 225,000 miles on it and yes check engine light is on but its been on for two years and the code is saying its cylinder 8 misfiring, it has always ran until two weeks ago, i had to have it towed and a couple days later i went out and it started right up i ran it for a week then it stopped, the temp here in ohio is aound 20 degrees

Was it warmer the day it started?

The reason I asked is that these are notorious for ecm/computer not sending signal when cold.

tuff4x4 r u saying the computer is going bad

That's why I asked if it was warmer outside the day it started.

yes it was but only by 10 degrees, ive been told i might have lost ground due to moisture

Ok. that's what I needed to know. These are very temperature sensitive. I had a dodge truck last week doing the same thing. This is how I condemned the ECM/computer. Go out to the vehicle, make sure it doesn't start, remove the computer.(It should be under the hood with 3 8mm bolts mounting it to the firewall on passenger side and 1 8mm bolt that mounts the wiring harness to it.) bring it in the house and set it on the dryer for a 1/2 hour (dryer on) take it back to the vehicle ,bolt the wiring harness to it and see if it starts right up.

Check all the fuses if you have a blown one for the coils you wont get a spark.

I almost have the same trouble, I went to Auto zone for check engine light they told me to replace the throttle sensor and manifold sensor, it works but next day won't start they told me to replace the crankshaft sensor and I did put a new one in but does the same way.... Keep cranking but won't start.

Can a paratisic test help find any electrical problems

I havesame problem with the 2002 Dodge drying 04 .7 except mine won't run when it's warm outside he says cold EGR but I don't think I have an EGR valve

Sorry 01 Dodge Durango code says egr valve but I don't think I have one runs great if cold out 45 or above shuts down

YES!!!!!!!Hey everyone, My 2002/ 4.7 Durango was having all the systems that has been posted on line about durango turnig over but not starting,,,, so I just so happen top crowl under the mid section inspect to see how not rusted my bolts to drop the fuel tank were,,,,,,and I see this hose hanging down from this cannister with three other hoeses attached to it, it was split and so I taped it up and reattacthed to the canniater and OH YEA it started after a few turn-overs of the engine,,, Praise the Lord!!!!
