COLD Hard start/rough running
 

I have a 2006 F250 and have been having trouble starting truck. It always starts, but takes a very long time to finally turn over. The truck also has trouble keeping up with itself (no power) until the engine gets up to full operating temp The transmission also seems like it doesn't want to shift as well until the truck heats up. Once truck is hot and up to temp (takes about 30 miles of driving) the truck runs perfect and will start right up. Ford wants to charge $1800 to replace the HOP (high pressure oil pump), but can't guarantee that is the problem. Since I just spent $1700 at ford to fix the problem and they replaced the FICM which didn't fix my problem I a very apprehensive to give them any more of my $$$$. Anyone who has had this problem PLEASE HELP!!!!
