erockskj, How many miles on KJ CRD and have you check the FCV lately? I had a similar problem (21,000 Mi.) and found the FCV sticking closed after long commutes. Engine would crank but sounded starved of AIR. Repeated cranks would only make engine sound worse. After the last incident with my wife stranded for hours, I removed the 3 inch flex hose (intake) at FCV, a slight push of FCV butterfly un-jambed it and presto! Started like nothing was wrong!!! Seems the soot was jambing butterfly closed after the engine was hot. THE darn thing was sooted-up beyond belief!! Both the valve barrel and butterfly were coated and the flats of the butterfly had caked-on soot crud preventing it from releasing after shutdown sequence. CLEAN THOSE FCV's.

I'll post pix of my before and after cleaning shortly. Word of Caution! The butterfly can be removed for more thorough cleaning but CAN BE reinstalled slightly of mark and bind during normal operation. MARK butterfly if removing insure proper position within barrel when in fully closed condition.

I did check the FCV and it was fairly clean and moved freely. I think I have learned a lot
on this web site ( maybe enough to be dangerous ) Knowing that it`s either fuel or air
related and would not crank, my only option was to have it towed to the dealer.
By the way , only has 25K on it now.

Yep that's pretty much the same senario that happened to us. But I didn't want to clean it, I just unplugged the darn thing.
