Have an 05 Dodge Gr Caravan sxt (149K+mi) my problem is that when it's cold weather it doesn't want to stay running, in spring like it's ok. I've changed MAP Sensor atop engine (big 6)
checked fuses, relays, reg maintenance. Have been told it's the fuel pump which is in the tank. But why only in the cold weather? Does anyone have any suggestions

 

Does Reg Maintenance Include Plugs and Wires????? Has the Throttle Body Been Cleaned?

I wouldnt Shoot right to a Fuel Pump Just yet....

 

General Motors and Ford have both had problems with fuel pumps after a cold soak, this would answer your question about why only in cold weather. I agree with Unclediesel, check everything you can before you condem the fuel pump, not only is it expensive, it requires the fuel tank to be removed to replace it.

 

Thanks for the info, Yes reg Maint includes plugs & wires. Not too bad on my gen'l knowledge for a girl. I do what I can reach, this is my work car, that's Y so many miles. Hope that doesn't sound too B itchy. I'll find the throttle body and check around. Thanks again.

Guess it's time for the work manuals!

No--Not at all...

Actually that would be when "Soccer mom" comes into the shop, complaining that she will never buy this brand vehicle again.....She complains that when she accelerates hard, or stops hard, there is a Banging noise in the rear of the van...... Only to find a SOCCER BALL rolling around in the back..... And she thinks it should be under WARRANTY

Anyway.....Yes .Fuel pumps can get quite expensive, because we no longer sell "Fuel pumps", we sell "Fuel Delivery Modules", which is a complet pump housing, Float, Vapor sensor, and pressure regulator. They can still be purchased aftermarket, But I personally have had Poor luck with aftermart pumps...Avoid the expense to find out you were wrong.......

Why was the MAP sensor replaced???? Was it bad , or an attempt at this issue?

Go to the air filter box...follow the Big black hose to the engine, remove the clamp, and pull the hose back....Presto, there is your throttle body....

I may be overshooting here, but DIYers are drawn to the "Quick-Books" available at the parts stores. Unfortunately, there comes a time, (Like THIS) where the Over the counter books just arent in depth enough..... If your serious about working on your own car, and you can bear to part with the cash....The factory service manuals are available thru any MFR's dealership parts counters....Both Book and CD/DVD versions. You will not regret it.

 

My car is a Ford products ,it just ok haven't comes out a problem i drive it nearly 2 years
