My nephew has an 03 ctd that isn't starting very well. It takes a long time to start and will start after sitting for awhile. Lift pump was replaced about a year ago. I suspect that he has injector problems. It has about 158,000 miles on it. He bought it used. He's a contractor so needs the truck daily. Any thoughts on a good deisel shop in Colo Springs ,Co would be appreciated. Thanks ,Brett
