The truck will not start if temp outside is below 45 unless I really crank on it. I am assuming I have a glow plug or cold start issue there. If I plug it in everything starts great. Once the truck is started it runs poor and dumps white smoke everywhere. Even after the truck is up to temp the smoke continues. It also started cutting out everytime I would pull away from a traffic light and would take a min for it to catch up... almost like i was flooding or not getting fuel. Every now and then when Im driving about 55mph and 1500rpm the truck seems to cut out or jump. Finally the other day I was rolling to a stop at a light and the truck just died. When I put my code reader on it the only code to come up was for a crank shaft sensor. I have replaced the sensor and still nothing. The truck cranks freely and fast but nothing. I have also removed the egr valve (during the time it was still running) and did my best to clean it up. There was a lot of black tar like material everywhere. Now when I turn the key I can hear the fuel pump running under the driver door. Any Ideas??? Hope someone knows whats going on because I am lost! FCIM??? High pressure oil pump???
I'm not a tech but it sounds like an egr cooler leak. I had the same symptoms you have and had to replace oil and egr cooler. If your egr valve was moist which it sounds like it was I would think it is the egr cooler. Good luck maybe a tech can give you more advice. Also might want to give more info about your truck. That might help them diagnose.
Do you have gauges to monitor oil and coolant temps? If you do, see if the difference in temps is below or above 15* at fully operational temp. on the hwy. doing 55-60 mph for a straight run for about 10-15 minutes. If it (delta) rises above 15 you probably have an EGR cooler leak.
