Dodge dakota quad cab 03 4.7 have to start 2-3 times. Only time that it will start on first time is just a few mins after shutting off. Have had tune up vacumn line replaced at dealer. Tired of paying for everything except what the problem is. Thought I would let it break and then fix but it's been 3 months now. Anyone with a fix I would really appreciate. Thanks.

 

Fuel pump or clogged injectors?

 

If jkeaton is right, I know of some injectors that will give you ooomph!!
