Hi !

I bought a 1998 dodge durango 5.9L recently for cheap and 2 days ago, while driving my car shut the hell down !!! for no reason. I step down the emergeny lane and wait for approximatively 20 mins till the engine start again. And now It happens all the time !!!! I don't know what to do !

Can anyone help me !

 

It sound like something electrical, like something is overheating and shutting down. Maybe PCM? Does it just shut down or is there something that precedes it? When it shuts down does it just die or does it do something like sputters and dies? Any particular outside air temps that it happens faster or later in your drive? Could you please give some more details please

 

try this, next time it shuts down take a bag of ice and place it on the PCM (electronic module on the passenger side fender well) and try starting the truck, if it starts your PCM is overheating and needs to be replaced, this is a common issue on dark colored trucks from 98-00

 

+1 Sharps


Also could be a fuel pump getting hot because you are low on gas.

 

+2 for shrps

 

Thank you everyone for your answer !!.
First of all, yesterday I talked to a friend of mine and said maybe it is the ASD relay... I don't what it is or it does . Can anyone explain to me ?

Second, I'll tryshrpshtr325 advise next time if it works.

Can a scan tool detect the overheating PCM or not ?

Tahank you !

 

ASD is auto shutdown relay, i believe it is a failsafe for accidents and such that it will open (open the circuit, lol) so that the fuel pump and ignition dont keep running,

either way if its bad the truck wont start, swap it with one of the same number

and no a scantool cannot detect PCM temperature or if its overheating.

 

OK thanks for the update !!
I'll try to swap to another one !

This morning, I drove my car for about 10 miles and no exception the car stopped. I could restart the car after 10 min. I try to apply a bag of ice and try starting the car. It didn't work either.

I'll go the dealer store to see if they can check the PCM before buy a new one.
Otherwise, google and this forum are my friends

 

You are supposed to put the bag of ice on the PCM before you drive it and see if it shuts down. This keeps it cool and doesn't allow it to overheat.

 

change the coil. there known for being bad with the 5.2 and 5.9 the brake down then they get hot and you can pick one up really cheap at advanced auto and you dont need to pull the old one off to check this you can do it right then you actually have a stall case. pull the plug and the coil wire and plug them in to the new one and see what happens
