I have been having a problem with hard starts. the truck has been to the dealership 2 times and is scheduled for the third this week. Over the weekend the truck would not start and I removed the fuel filter and put it back in. The truck started right up. Is there a sensor in the Fuel filter assy that could be not working right? The truck also is starting to get a rough idle every once in a while. Any suggestions?

 

How old is the fuel filter?

 

Filter was only a week old

 

I'm not aware of a sensor, bad fuel maybe??

 

Transfer pump might be going out. Better have them check fuel pressure.

 

Id take the hypertech off and see if the problem goes away

 

my truck to idles rough now and then. its a 2004.5 dodge ram 2500 Diesel 5.9 cummins

It comes and goes. when i come off the highway or after ive been working it it runs good. Putter around town here and there and never get it hot it idles rougher.
