If there is fuel pressure, you must then check for the injector timing pulse. NAPA had a kit containing IODS for the most popular manufactures injectors. You unplug the wire at the injector and plug the Iod in. The Iod will flash when the engine is cranked if there is a pulse. If it doesn't I would suspect the crank position sensor. My last choice would be a bad EMC. I would check the big plug at the firewall, perhaps unplug it and clean it with electrical cleaner. With no code, this is what I'd do. Good luck.

Just some more thoughts as I reflect on your problem. I forgot that Iodes are actually called Nodes. Also, the first thing I'd do if you couldn't read any codes is to disconnect one of the battery cables for a few minutes and reconnect it. This will reset the EMC to the default settings and might eliminate the problem. Lastly, hope you don't have a broken Timing Belt. Let us know what you find out. My 05 CRD has 93k miles. I have a new belt, water pump, and tensioner as a kit from NAPA, but because I'm a full time RVer and the CRD is my Tag along, I have to wait until I'm at my friends farm where I have all my tools in my cargo trailer parked there. Some owners have gone 130k miles before changing it and others have had the timing belt fail way earlier. If it breaks, the damage can be bad.

possibly turbo failure.

#11324 of 11441 Turbo failure? by elder2

Maybe the turbo, but I had a cracked intercooler from my wife hitting a deer and she was able to drive the CRD back to the farm. I have a boost gauge and knew from zero pressure that the turbo system was the cause of 35 mph max & slow acceleration. I started fine and idled well. Just from my experience.

Hey cdp3. Whats happening with the CRD? Any news or clues. I'm currently in the Yukon on my way to Alaska, so internet is not easy to find. I hope you got the little Jeep running.

elder2 has some good points, check the least expensive first, the Crankcase position sensor, if this fails the engine will not start, sometimes they can be cleaned but usually they need to be reploaced.
There may also be camshaft position sensor (s) that also will stop the engine if it fails.
I had one fail on my Porsche and it would turn over but not fire.

#11327 of 11441 Lurching and losing power by jim66wright

Aug 20, 2012 (6:25 am)

this weekend, the 2005 CRD started acting like it was running out of diesel. I looked at the fuel filter and it had 40k miles on it! Never looked at it, bad mistake. Changed it by taking the unit off the fire wall and replaced it with a new one. No leaks, when I pumped it up, and it still lurches, like it was sucking air or something. I keep pumping the air out, so I think it is sucking air in somewhere. There are no codes, and it idles perfectly. I drove to work, and it would do 70 but there seems to be no turbo and still starved for fuel. It takes a full press on the peddle to get it just running without missing and lurching. Y'all helped me with the water pump issue, hopefully this will be similar.

Costs were cut on the Liberty CRD, one of which was not putting in the In Tank fuel pump. The wiring is there, located under the carpet (rear seat drivers side), Many of us have picked up a fuel pump, fuel gage sensor from an early 2000's Dodge diesel truck, either from EBAY or a wrecking yard and installed in inside our tanks. This gives the fuel system positive pressure to supply the engine driven fuel pump which has to suck the fuel all the way from the tank. With positive pressure everything runs smother and any "air sucking" is eliminated. Some have chosen toinstall an in-line seperate fuel pump as close to the tank as possible rather than drop the tank and install a more original design set up.
The most likely culpret for your "air sucking" are the "banjo" styly fuel line connectors back near your fuel tank. These are notorious for leaking and should be replaced with common hose clamps.
There are tutorials on line on just how to install the in-tank fuel pump.
Hope this helps: Bob

Thanks, Bob. I will do so. The dealer here in High Point, read 5 codes yesterday, and says it is lurching due to the glow plug module. Strange. I am paying him $100, and getting my Jeep back. He wants to replace all the glow plugs, and the module for $785. Sounds crazy. Starts great, and idles fine, but under load, loses power. I will post the codes once I have the Jeep back. Great idea on the fuel sending pump. Will do right away.
