I have a 1997 h1 that I’m working on for a really good customer. He called having issues with the truck cranking. First we have had to replace the orings on the injectors and the return lines. Then the hummer crank really good for us then the customer got it and starting having the same issues again so we picked the ride back up from him and started messing with It again. We noticed the hot wire going to the starter had melted the thermal almost off so we replaced the starter. And the vehicle started cranking easier for me but still just not what it needed to be so I took it back apart and spun the vehicle over with the lines off the injection pump and noticed that it’s only spraying fuel out of one maybe two of the spot where the lines goes anyone have some ideas? I’m kinda leaning to the injector pump. ( I have replaced the lift pump also)
Feel free to give me a call at anytime if you can help me out 3184535185
