I went to start my truck today and all it would do is roll over. I did this for 5min until it finally started. This also happened yesterday. Driving down the road it would chug a lot no matter how I shifted or got on it. I have new can phases plugs and coils and also recently new cats. What could the proyblem be.

 

Any help would be appreciated thank you

 

What are you working on?

 

Took 5 min to start truck . Kept rolling over and nothing. When I got it started and drove down the highway it would chug a lot . I have new plugs coils Camphasers and cats. Not sure what to do. This happened yesterday also

It could be a number of different things.

It has to have a CEL on if it's chugging. Can you get the codes read?

It could be injectors, fuel filter, fuel pump, throttle body, MAF, or the FPDM.

 

No cel on have new filter. I was thinking fuel pump but wanted to make sure before I have it installed. Anything else you think for sure could be the problem.

 

Before you think fuel pump, check the FPDM.

 

What's fpdm

 

fuel pump delivery module

 

It's on the crossmember above the spare tire, they corrode. You need to remove it and check the back side.

 

I just did mine a few months ago. It was so corroded and cracked open, I cant believe they location they chose for this think.

 

It would have been fine if they had used standoffs at the factory. Replacement ones can be bought with a standoff kit.

 

thanks for the help. This is what's wrong with mine. I'm getting hosed 400dollars for the dealer ship to put it in. I'm unable to do the work do to some injuries I have. Thanks again.

 

Sorry to hear about getting hosed... but on the bright side, you'll have a functional truck again.
