I just replaced my 2003 2500 SLT. 5.7 Hemi with a new 5.7 Hemi crate motor and now I am having a starting issue. I did not have an issue prior to the swap and I have had the injectors cleaned and tested and added a new throttle body and all new sensors.. After sitting over night it will start just fine but after it has been running it will not want to start I will need to keep cranking it or put my foot to the floor.
