help!

I have a 2000 X 7.3 diesel 70,000 miles and lately I have noticed that on some start up the engine runs like a cummings. It sounds really load and the knocking is very noticeable. What I have to do is turn it off and on a few times and it somehow fixes itself. This morning I went to fire it up and there was alot of blue and white smoke coming out of the tailpipe and it sounded horrible. I had to turn it off 5-6 times for to run normally. I have replaced the Cam Position Sensor because I thought that was the problem. Has this happend to anyone else?

jcuzman75,

Check and see if any oil is also coming out. This happened to my sister's X and it locked up on her going 65 on the interstate. They did a test and she had 5 bad injectors. Have a buzz test done on the injectors before trying to pull them. It is a involved process to pull them so do the test first. I hope you get this resolved.

BTW-Welcome to the garage!

Does it run fine once it's warmed up? Mine did the same thing, I had to cycle the key several time and overload the cylinders before she'd fire. Some times you can run a 12V hot wire to one of the small posts to force it to engage, but make sure you disconnect the small wires (I think one is linked to the pcm). Good luck bro!

It would be best to have a diagnostic test run on it. :Thumbup: you will spend alot of time and money trying to find a problem like this. you already put a cps on it, you didnt need. welcome to the site.

Maybe the cps wasn't the problem now but chances are it would have been soon. Hang on to the old one for a spare.

Let us know what you find out on the real problem. Good luck!!
