New to the site, and it's already been a wealth of information. So thank you for that. I have 2 '06 CRD's and hope to keep them forever.
I've read the Noob guide and a host of other threads, when I've had some issues, and have always found the right information.
This particular jeep I just did the Weeks stage 1+2, Hot Diesel Thermostat, "upgraded" the glow plugs to the 5V Bosch metal ones, number one was burnt to a crisp. Also replaced Vacuum lines with silicone lines. Samco Hose upgrade, and the turbo Hose intake upgraded to Silicone. Has 230,000 on it, and just replaced timing belt about 30 grand ago. Other than that, everything else is stock. What a difference removing all that EGR stuff, takes off like a Jet now.
Little history, I've had it for just over 2 years, and twice it's gone into Limp Mode, and I've never really figured out why. There really wasn't anything I really did. However after the first time, it was Timing belt time, so I did all that, and it was fine. Did the limp mode thing again and after a week of sitting just started up and was fine. Thought it was a vacuum issue, so replaced the lines and ran fine, but it really didn't seem like any of the old lines were bad. It also takes a few extra seconds of cranking to start, nothing crazy, but it is a bit elderly on the miles.
Only codes it's thrown are the Glow Plug code. I use torque lite, so not sure if it's reading everything that's there. Now, of course it's throwing all the EGR codes. Since GDE doesn't do the tunes in the US anymore, I'll have to use one on here, again, glad that info is here.
So, now the real reason for the questions... it ran great, drove it for about a week, parked it at night, the next morning, it cranks just fine, and won't start. Changed the Fuel Filter, as I'm in Northern Ohio and it was a bit chilly overnight but nothing crazy, verified I'm getting fuel at the rail, even took off the hose to the pump to put diesel in there and won't even cough like it wants to start. Block heater is plugged in and charged the battery to make sure it's cranking full. I've read the Crank no start no code threads, but nothing ends up being what it appears mine is doing. I don't want to just throw parts at it, but it doesn't seem like there's very many things that can make this not want to run.
I am thinking Crankshaft or Camshaft sensor, but wouldn't they throw a code? Does Torque lite maybe not read those codes? I currently don't have a way to get any real fuel pressure readings, but cracking number one injector appears fuel is pumping just fine.
If I do just throw a crankshaft sensor on it and it works, I'll still scratch my head because I hate not knowing why it's not working or throwing a code... or maybe I just need a really good Code reader.
Any ideas would be greatly appreciated, even if the consensus is to just throw a crankshaft sensor on it to see.
