Question about Dodge Grand Caravan

1 Answer

My problem is that when I start my van cold it works fine. As I run errands and stop for 15 - 30 minutes, when I start the van it runs very rough. If I pump the gas and get moving it smooths out and runs fine. I have been told that the check valve in the fuel pump is leaking causing fuel to leak back into the tank. If that were the case wouldn't it start rough all the time?

have a pressure test done on the fuel manifold to check for pump-regulator pressure and filter performance. You state that the filter was last changed in 2007 so it is well past it's blocked up date .. Run fault codes . replace the canister . Have a compression test done as the engine is getting long in the tooth and may need refreshing .. Check that the cat converter is still operational as they will block up the exhaust system and cause poor performance

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m


Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

No fuel when car is hot - won't start


I doubt it is the ECM, that doesn't really make any sense to me. I believe your fuel pump is the issue. What do you mean it isn't on under these conditions? When you do a long errand it start and is fine, right? It is heating up during your drive, then won't start up after your short errand. That's why I ask if a longer errand would be fine, and obviously in cold weather, this would be the same. A longer errand lets it cool down.

Does the engine crank and turn over easily when it is hot? If not, it could just be the battery, but I kind of doubt it. Also, you are using premium 92 octane gas right? That care needs it.

Lastly, if you give it some gas before you start and while you start it, you may get it started. I'd hit the pedal a few times before starting and definitely hit the gas when you start it.

It's not the ECM; I would be shocked.

Good luck!!

Its because that the engine is very cold, try to worm it up more time before you start driving.
