I would also have to presume that the plug was reinstalled in the correct orientation. At InjectorsDirect.com it is not only our job to provide customers with the best experience possible, it is our purpose. Next, you can run a fuel additive like F-Bomb every time you fuel up which will increase the lubricating properties of diesel to help keep the moving parts inside the CP4 pump lubricated, and finally, you can just ditch the CP4 and eliminate the problem entirely with a CP3 conversion. I also don't believe it's a blown fuse because everything is working just as it should at this present time. 1. During those 15 years, DMAX Ltd. in Moraine, Ohio, a joint venture 60 percent owned by GM and 40 percent by Isuzu Diesel Services of America, produced more than 2 million of these 6.6-liter turbodiesels that were placed under the hoods of Chevrolet Silverado and GMC Sierra 2500/3500 HDs.
