My 2005 5. 9 with g56 6 speed was giving me fits with excessive crank before start. The problem was intermittant since the truck was new. Mopar said they were working on the problem and for me to keep checking with dealer. After almost 2 years the fix is out on tsb 18-003-06 and I think they finally got it right. They had an issue with the duel faced fly wheel and the crank position sensor. The TSB reflashed the ecm.
