Re:TIMMING 24 VALVE CTD.
The Timing on your 24valve ISB is electronic.<br>Your Crank, Cam and Fuel pump gears are zeroed with each other at the factory when installed and your fuel pump has a tooth (pump specific) that is timed to the gear train/assembly.<br><br>I would start with checking fuel pressure from the lift pump, a weak or dead lift pump will cause a crappy idle and low power.<br><br>--Justin

I believe pre filter pressure should be around 12 to 14 at idle and around 6 to 10 running at around 2000 rpm. I went from an 01 to 98.5 and to me they sound a little different why I dont know but they do. Little bit more motor noise. If you do need a lift pump get it from cummins and not from dodge. Better price and better warranty, mine was 160.00 and has 12/100k warranty. They are not that hard to put in. It took me about an hour and I even put in the banjo kit from wildcat.
