P 0336 Code and major injector rattle with new TST!

[Blacksdieselhp]

Just got a new TST for my 2003 truck and it ran awesome the first day. I drove it this morning and the inejctors were hammering away. A lot louder rattle than the normal timing rattle that is common. Also, when I tried to lauch the truck from a stop, it wouldn't spool up, it would just bog. Then it went back to working fine. So when i pulled in the shop, i revved it a few times and it reved smooth the firts two times, them the rattle came back and it wouls stumble around 1100-1200 rpm. I checked all connections and everything is good. I've had several dodges and have never had to replace a crank sensor, but it looks like that may be the problem. Any thoughts?
