Hello, can you check for codes? Try cycling the key, on--off, on--off, on, you just turn the key till the dash lites come on, no crank. The check engine lite goes to flashing, you count the flashes to get the codes.

You could do some basic tests, if it refuses to start again, right away. Have a helper crank it, while you check for spark at the plugs and injector pulse.

Hi brobert.
Yes, like [ jdl123 ] said, cycle the key and note the codes. Have paper and pen ready...
Did you read some of Thee Excellent infos @t:
https://www.2carpros.com/first_things/why_does_my_engine_die_stall_at_idle.htm

I'm having a similar problem:
1995 Caravan, V6, 3.3L, automatic, 225 000 KM = Last model-year of same generation as yours.
It starts but will not idle! Runs smooth when i give it gas, but will not idle! repeated self intentionaly
btw > I live in Montréal, Canada. Cold and/or wet winters!!
Here's what I've noticed in the last weeks:
Battery seemed to weakened (Slower turning starter), Radio-clock will not work (Fuse good).
Then today=
Tried to start Caravan. Cranked ok, fired-up, revs-up, but unable to idle. I had to reStart 3 times.
On the fourth try = Battery too weak to do it's job. I used the jumper pack to reStrat it 2 more times.
Reved-it-up for 1 minute to recharge both batteries. Still no idle = stalls!
Here's what I've done, and discovered:
Removed my battery to take it inside, inspect the liquid level and recharge-it. Yep! It's low on water.
And it has ONLY! 11.97 Volts. "it's DEAD Jim!". I topped it with neutral water and put the charger on.
(Last time i did that on previous car's batt., it did not bring my battery back to scale!) Still trying...
I'm suspecting that the too low VOLTage might have induce errors in ECM... I'm just guessing.
So I went back-out to the Van, and cycled the codes using the Power-Pack. Hey! The radio is ON!?!
But! Since I removed all power to the Computers for over 1 hour, codes are useless.
I only got 12, and 55 wich is END of diagnostic according to my Haynes Sunday Mechanic book.

Ok. Loooong post! Sorry...
I'll let the 1 amp charger do it's work overnight, take a measure, and see about this trouble tomorrow.
Maybe will have to go buy a New Battery... Hoping that will end this Stalling Trouble!!!...
N.B.:
And I will post here with latest news. Ciao Dude.

Solution:=:=>
Replaced The Old, "it's Dead! Jim", Battery. Circa June 2006.

And now it's OK, xcept for the Radio-Clock that still won't come on!
Starts, idles and drives.

Did not have to replace any symptomatic sensors/valves :
Being;
, IAC= Idle Air Control Valve,
, MAP= Manifold Absolute Pressure,
, EGR= Exhaust Gas Recirculation
, Oxygen sensor, on Exhaust Manifold,

Darn CONmputers!
Electronics should have NEVER been Mixed with Mechanics!
I can understand it for emissions and performance, butt! Error intented = Cause it's a pain in thee!
But Pe-Leazzz! Make them better than Windows! I mean PLEASE! Come! On!

As for the radio-clock that will not come on, I'm now suspecting said accessory.
But who knows, , if it's still because of that Darn little silver box! = Dah CONpiouter.

Have a 94 dodge grand caravan se (3.3L v6) that has stalled a few times. It sat for 6 months with a full tank of gas till I bought it. The engine light comes on at times then the van stalls no matter what speed I go. I try to restart it but it seems like its not getting enough gas.

If the check engine light is on, lets start there. Take the vehicle to a nationally recognized parts stores and have them scan the computer for trouble codes. Most will do it for free. Let me know what you find.

1994 Dodge Grand Caravan, 3.3L, AWD, 113,000+/- miles, stalls when hot. This has happened at low speed, <30mph, once when pulling away from stop sign, at about 25mph (light acceleration) and once while slowing to make a right turn. No computer codes (55 end of sequence only). Will restart after 30 minutes or so and run fine. Fuel pump and filter replaced. Still stalls. Fuel pressure seems fine. It will squirt out at the pressure release valve on the fuel rail with a pretty strong stream. What next? Thanks.

The most common cause is a failing crankshaft position sensor but the camshaft position sensor can do that too. They will typically fail when warm and work again when they cool down. When the signal is missing from one of them, the Engine Computer turns off the automatic shutdown (ASD) relay which removes voltage from the ignition coil pack, injectors, alternator field, and fuel pump relay.

Went to the mechanic, and he said I needed to change the gas pump and filter from my dodge caravan 94, where can I buy the right ones, good prices, so I can bring it to the mechanic?

The car was dying on me, so I have to change it, but the store wants 230 bucks for it

Check auto zone, pepboys and advanced. They all stock them but you have to release the fuel tank and lower it to get the lines off the top of the pump module.

Well it will crank and fire up, and will take gas and run perfect for about twenty to thirty seconds. Maybe a minute, but it will soon shutter and shut off. But I have found out after doing this several times. That if you just let it run without touching the gas. It will just shut off real quick. But if you pat the gas while it is shutting off it will act like it's going to pick back up. But after sputtering up and down from a good idle to about to shut off it will go head and shut off.

So, I thought fuel pump so I changed it and still the same.

So then I went to the firing and found out that I wasn't getting no fire threw the ignition coil. So I changed it and it started get fire but it wasn't right. It would only fire about one time on the number one spark plug wire for about every six to eight times it would turn the engine over.

So then I changed the crankshaft sensor.
Still the same.
So I changed the camshaft sensor and still no change.

And I've checked the fuel pressure.
And the fuel filter.
And air filter.

And I do not know if this may help but it has a knocking sound when you let it idle or when you let off the gas and it gets about down to 20-30 mph and stops when you get to about 5 mph. The noise sounds like it is the dust cover on the catalytic converter but it is not.

Hi and thanks for using 2CarPros.

Are you sure the internal components in the catalytic converter are loose and plugging the exhaust?

Do me a favor. Do this test and see if makes a difference.

It sounds like it could be internal components in the catalytic converter. Start the vehicle and allow it to run while you check if the sound comes from the exhaust. If it does, allow the engine to cool. Then, take a rubber mallet and tap on the exhaust to see if you can reproduce the sound.

Let me know what you find.
