I may be in the wrong place, but I figured this might be worth a shot. I have a 2006 cat th350 forklift (diesel), a few weeks ago the machine would shut down, but would crank back up. We replaced the injector pump after our mechanic said that was the issue. After replacing the injector pump it ran strong for about a week then it started to shut down gain. Called the mechanic out, some how water was in the fuel system, flushed lines, new filters, and added fuel treatment. Now it is doing the same thing it was doing before we placed the fuel injector pump. Run for 30 seconds up to a few minuets and shut off, sometimes it cranks right up and sometimes it takes a bit. We checked all fluid levels and everything looks to be ok. Can any one please help me, I wish I had more information to offer?? Trying one last effort before I spend out the rear by taking it to the cat dealership. Thanks for your help in advance.
