Have you checked fuel pump pressure? Also, is the clicking coming from the idle air control valve?

I have not checked the pressure as I do not have the equipment for that. I also could not find where the clicking was coming from before it stopped. On top of these two possible causes, can you think of anything else? One other item of note is that when it was somewhat running there was white smoke coming out the exhaust. Could a blocked catalytic converter cause this?

I didn't know about the white smoke. That usually indicates a bad head gasket. You will need to check engine compression for that.

I don't know where you are, but most nationally recognized parts stores will lend or rent tools to you. Most just ask that you pay for the tool, and then you are refunded the full amount when you return it.

Let me know.

Dodge Caravan 1990, 175,000 was running fine one day. Next day, put van into reverse and slowly backed out of driveway, put into drive. When I stepped on the gas slowly, the van engaged and moved forward - to about 5 mph. When I pressed on the accelerator again to go faster, the van started slowing down - almost to a stop. It doesn't stall - but feels more like someone is stepping on the brake simutaneously with the gas. After several attempts, it continued doing the same thing over and over. When put in reverse, it does the same thing. My husband is capable of simpler mechanic fixes so any "quick fixes" you can recommend wil be tried. The previous owner took pretty good car of this vehicle and I've owned it for about 2 years, just driving it around town. It had rained a lot the day it started this so I thought maybe it had something to do with water somewhere, but it's been about 2 months now and still does it - making it non-drivable. It also vapor locks in the summer - if that is any help. Thanks for your time!

Is the check engine light on? Have your husband rule out the simple possibilities. Check the rear brakes to be sure something isnt broken. Be sure that you can spin the front wheels both directions by hand. Might be a trans problem

The cold weather brings out the worst in any electric or mechanical part. If you have low fuel pressure you will notice it more in the cold. If you have a sticking IAC motor on the throttle body, same thing. Also in 89, the computer for the engine was not very quick to store a code. It may be a good idea to clean and test your fuel system. A coolant sensor could also be off, yet store no codes. Your gouing to need someone to roadtest it cold. Try and bring it somewhetre and leave it overnight for the technician. Try to have an ASE certified tech. Look at it. Maybe some fuel dryer and additive may help. In 89, there were very few cars and vans that stored codes. It was one 'no code' after another. But you have some pretty high mileage, if you never had to replace your fuel pump, this may have something to do with it. And the idle speed motor can also stick, neither will store any code. They sell a nice fuel pressure tester. At the store. I got my eye on it. These gauges were 200 dollars in 89. If you need anything feel free. I would need to drive it to be sure. And know the engine size and history of repairs. Ok

1989 Dodge Caravan 4 cyl Automatic 120000 miles

My 1989 Dodge Caravan will start and run for up to 30 seconds but as soon as you go to put it in gear it will die. If you try to restart it it will just die faster and faster and then if you give it gas sometimes it dies faster but sometimes it won't. I am also getting error codes 12, and 25.

Thank you for getting back to me. The car will not stay running for anything. Sometimes it will run longer if you give it gas but mostly it dies and if it is cold outside it kills it quicker when given gas. But the longest it will run right now is 30 seconds and that was yesterday when it was 70 outside.

88 dodge caravan w/2.5. Engine does not stall or misfire but will occasionally die as if the key was turned off. Usually at thermostat opening or after. When it first started doing it it would simply restart. Now it takes about 10 minutes and the key has to be turned off. Till today, it would only do it once and then be fine for the rest of the day. Today it died three times in 30 minutes. Fuel pump is working with the key and there are no codes stored that I can find. Any ideas?

Change the Hall Effect Switch under the rotor in the distributor. Very common problem. Also called the pickup assembly.

Change the Hall Effect Switch under the rotor in the distributor. Very common problem. Also called the pickup assembly. When it fails, the fuel pump will run for the initial one second after turning on the ignition switch, but it won't turn back on during cranking. You won't have spark either.

Would the pickup still be indicated if the engine never has a problem starting when its cold or sometimes goes three weeks before it does it again
