After the fuel filter change and priming the hell out of my 06' LBZ duramax it finally cranked back up. However it is idleing really funny and the message board on the dash will not come back on......what do I do now?

Let it run for a while, should come out of it.

Yea I let it run for about 5 min. and it started running normal again but then went back to the weird idleing. Any ideas on the message board problem?

Did you use a GM fuel filter? I didn't use one last time, and sometimes I have to prime it to start.

Yep GM fuel filter. I have always used GM but I have never had these problems.

man i really think there maybe something else that you might of revealed by changing the filter. you may want to tak it to the dealer. some 06 lbzs had fueling issues. and other problems.
