Re: crossfire cranks but will not start
"This is the reason that all modern engines utilizing this technology must turn over a minimum of 2 revolutions before actually starting.( Takes 2 revolutions for the PCM to get it's ducks in a row )"
Careful with the generalities. I have had a number of 88-92 GM 3800s (just have two left now) with CPS and typically all I needed to do was turn the key ON, give it 2 seconds to prime the fuel rail, just barely bump the starter, and the engine would be off. Do know the GM CPS had two rings, one with 3 teeth and the other with 18 but almost always started within 1/8 turn.
Have had quite a few engines with carbs and electric fuel pumps and once I would get done tuning they were the same: bump and go.
XF took some getting used to in that it wants to crank for a while before starting. It does have the autodisengage so I usually just put in neutral, turn the key to START and then push in the clutch until it lights off.
Now that I think on it, the Jeep usually cranks a bit but there I just put my foot on the brake and push the button, everything after is automagic so may crank a bit.
