My 1995 K2500 GMC has had six injection pumps put on it since new. Each time the shop replaces the injection pump, the truck runs like new again – for a year or two. The last time we had this done, our mechanic installed a different fuel delivery box. He said that the one mounted on the injection pump was the problem all along, so he installed this new one that is fastened to a finned cooling grid that bolts along side the intake manifold. He said that this would solve the problem we had been having. Well, it has not worked out that way. After 13 months and 23,000 miles, we are right back where we always seem to wind up – with a stalling engine. A friend gave me your magazine and I am thrilled to find information about my truck. I hope you can offer some suggestion that might help us fix this for a longer period of time – we need reliability!
