#62 of 194 1990 Dodge Dakota 3.9 Automatic
Jul 25, 2009 (12:56 pm)
Hi all, I have a 1990 Dodge Dakota 3.9 V6 Automatic. I have an issue where after starting the truck and letting it run for about 15 minutes it stalls and will not start for about another 30-45 minutes. Now I've replaced everything that I thought it might be and still havent solved the problem. I've replaced the ECM, distributor cap and rotor, auto shutdown relay, fuel pump, fuel filter, coolant temp sensor, and I dont know where to go from here. Please anyone or maybe a mechanic, if you have any info on this I would greatly appreciate it because I'm seconds away from driving it into a lake! Thanks, Mike

So, because I am dumb, I took my V8/auto tranny Dakota in to a dealer for it's first tune up and tranny service. The truck was running fine in all respects. I got back a mess. The tranny failed twice after getting the truck back, first the dealer blamed a bad new MOPAR tranny filter, the 2nd failure was a different bad tranny part (sorry can't find the paperwork). All this had the distinct feel of total BS coming from the dealer - as in I think the mechanic screwed up the tranny service royally, and they just wouldn't admit it.
Anyway - after the 2nd tranny failure, I got the truck back and it immediately began stalling shortly after morning start up - well within the first mile or so of driving, but only after the truck had been sitting a long while - like overnight.
Here are the exact symptoms.
Starts normally in the morning (I do not let the engine warm up - start and go, but I tried letting the engine come to temp before go doesn't have an impact on this problem). Drive to the first stop (uphill less than 1/4 mile away) as the truck comes to a full stop, the RPM's drop out and the truck stalls. Truck restarts immediately and does not stall again for the rest of the day.
Cold engine stalling is intermittent (roughly 50% of the time or less) in temps greater than 65 degrees, and almost always as temps dip below, with coldest winter temps causing multiple stalls, as opposed to just once in the morning, but again, will not continue to stall once warmed up). So the colder it gets, the more consistent and more frequent the cold engine stalling is until the engine warms up and then the engine will not stall for the rest of the day. I can prevent the stalling if I force the rpms to stay up by braking and tapping the gas simultaneously.
If I take a different route in the morning so I don't hit stop/go traffic while the engine is cold, I don't have a stalling problem (but it's a much longer route, and that's no solution)
Over the months, the dealer has had the truck back 5 times without success. They reset the computer on the first try, then replaced one of them (can't find the paperwork). Replaced the Oxygen sensor. Beat the engine with a hammer, had a Shaman do a pagan blessing, and then shrugged. I suggested the problem is tranny related because that's where all the troubles started, but the dealer says the tranny is fine.
Lawyers are expensive, and I just want my truck fixed.
Suggestions would be enormously appreciated.

I too have had a problem with stalling when the engine is cold. I have a 99' dakota with the 3.9 and a manual trans. This problem has existed for a while but it was more pronounced in the winter. I was reading these posts and since the truck need a new battery I picked up a new IAC valve at the auto part store while I was there. (cost about $30) I took the old valve out, cleaned the port that it was seated in with some carb cleaner since it was quite gummed up. I put the new valve in and my truck runs like a champ again. I hope that I never have to take that valve out again because I stripped one the screws when I was installing the new one. Good Luck.

'99 Dakota w/5.2 engine and auto trans. 110k miles. Problem started after hard acceleration and braking to stop. The torque converter or transmission did not disengage when I stopped and the engine died. Will run with jerky shifts after I shift into gear under power but still locks up and kills engine after highway run. No Codes present. Replaced TPS and IAC motor. Rear Band has a lot of play in the adjustment. No pieces in oil pan, normal Iron sludge stuck to magnet.
Researched threads for solutions:
2. Rear band misadjusted
3. Broken Clutch spring (no evidence in pan or filter)
4. bad front clutch (how do I check)
5. stuck servo (how do I check?)
6. valve body problem
7. broken Planetary Gearset (no evidence in Pan)
8. locked torque convertor clutch
Planning on making band adjustments, replacing filter and running to check. Or should I just go ahead and disassemble the thing?
Could this be a band adjustment issue or do I have a failed (locked)torque convertor? Since there's no codes I'm thinking the electronics are o.k. I heard valve body check balls shrink and fail?

Recently I had to replace a throw out bearing in my dodge dakota 4x4 3.9. I forgot to remove the crank position sensor and broke it off while removing or installing bell housing, found out when truck would not start. Replaced it and started fine, hesitated a second and ran fine till the next day, had too pull over and nurse the gas do too very rough idle and power lose, got it going and drove 30 miles and it hesitated a split second. Next day drove 2 miles started running rough jerking, pulled over rough idle when started. left it over night and it started right up and drove 2 miles did the same thing. Replaced distributor cap and rotor, nothing. Pulled IAC, very dirty, started truck idled great, shut it off for 10 minutes, tried to start it again, woul not stay running. Replaced IAC, same roughness. Changed crank position sensor know starts but runs rough like all cylindes not firing. Help I'm losing it...LOL

I just joined and I know your post was months ago. I have had the same problem and scanned my computer and found that I had no crank position signal. I assumed it would be a crank position sensor but found that even though the dealer and the parts store said I had one, I found that a 1990 dodge 3.9L does not. The loss of signal was coming from the coil pick up located inside the distributor. I hope this helps.
