FOR ALL YOU GUYS WITH COLD START ISSUES...
I'm pretty handy around HEMI engines. When I purchased my 2004
Dodge... the hard cold start happened right off the bat. So I took it
in for warranty work and they flashed the chip. It obviously didn't
work, so I took it in a second time and told them the fuel pump was not
holding pressure... that's why it starts rough after sitting for 30
minutes... and of course, that was the problem. Now it's fixed and
running sweet. Don't let them waste your time. Tell them to check the
fuel pump pressure.
