1999 dodge 3500 van

I was driving my van today about 65 mph and it just died goin down thee road no spit no sputter just like you turned the ignition off, and now it wont crank. Any suggestions?

and now it wont crank.

The engine won't turn at all or it turns slowly?

getting fire to the distributor , but not out of it, I have changed cap, rotor button, and pickup coil still no fire to the plugs

Bad/weak ignition coil.

I'll try that, but a mechanic that has worked on this van before said it has a history of this problem and he had to put two ecm's on it 3 months apart, I got a new ign coil and an ecm coming will try that tomorrow, bout ready to holler !

Thanks for your help Alloro, put a new coil and pcm and it cranked right up! I just hope I dont have this problem again !!!

You probably didn't need the PCM. The reason I suspected the coil was that you had spark going to the distributor just not out of it. That told me the spark was too weak to jump the air gap between the rotor and cap. With a bad PCM you either have spark or you don't.

Got another problem now, heater doesnt get hot front and rear and no air flow from top vents in the rear plenty at the bottom and in the front. any suggestions ? I checked the actuator by turning the temp control knob an actuator doesnt move, so I think thats the heat problem, but still can figure out why no top air in the rear.

Is the engine getting up to temperature?

Is the engine getting up to temperature?

Yes it is I found the heat problem, the core was stopped up, but the other issue I have now is in the rear, plenty of air flow from bottom vents, but none in the top vents

Sounds like you'll be chasing a broken vacuum line or an actuator with a ruptured diaphragm.

would it be located around the rear condenser and blower motor ?
