Problems running when first starts up
Hey guys I had just bought my first Dodge a few months ago, it is a 2002 Ram 1500 SLT with the 5.9L Engine. Whenever I would leave the truck sit over night or for a few hours I would go to start it up..It starts up fine with no problems what so ever, but a little after starting and I would go to drive it would like hesitate to go and the RPM's would drop super low almost like it is going to stall but it never stalls. Could this be like a Air/Fuel Sensor or something?

Any help would be greatly appreciated.

Thanks guys.

When was the last time the fuel filter was changed? If it looks old/dirty I would start with that. If it is clogged it is not allowing the amount of fuel needed when the accelerator is applied. Another cause could also be the solenoid in the starter on its was out or getting too hot and not functioning properly

have you tried to pull any codes? even if the check engine light isn't on.

Hey guys..the guy at the Dodge Dealership said the fuel filter is attached to the fuel pump or something like that and I couldn't just buy the fuel filter?? I dont know ha. and no I didn't check any codes I will try that next. but yea my check engine light isn't on. But after it warms up after a little bit it runs amazing.

here is a copy and paste from the service manual :(

The fuel pump module assembly is located on the top of the fuel tank . The complete assembly contains the following components:

A combination fuel filter/fuel pressure regulator
A separate fuel pick-up, or inlet filter
An electric fuel pump
A lockring to retain pump module to tank
A soft gasket between tank flange and module
A fuel gauge sending unit (fuel level sensor)
Fuel line connection
The fuel gauge sending unit may be serviced separately. If the electrical fuel pump, primary inlet filter, fuel filter or fuel pressure regulator require service, the fuel pump module must be replaced.

haha so that means I am pretty much screwed and need to get that whole assembly? ha I love how they make everything attached to each other. Any idea what that would cost? not necessarily mopar I could get aftermarket also.

Thanks a lot for the info I appreciate it.

I may have jumped the gun with my post above b/c I wasn't thinking. That copy/paste is from the 2009 manual. I did a quick google and I found this part for your year truck. So maybe your filter is replaceable but it still might be inside the tank...IDK.

CHVYKLR 09-07-2011 10:26 PM

are you sure you need to replace it?

I have a 1996 dodge ram 1500 and my truck too has the same setup as was suggested for the 2009, maybe its the same for all rams?
