Hi guys
My vehicle is a 1997 GMC Savana work van , 6.5 motor ,non turbo. I bought it from my father 3 years ago. Unfortunately, the computer module went bad for him and he had to have the injector pump replaced two times. Since owning it, I put about 40 thousand miles on it and had to replace the injector pump once myself.

At $2500.00 for the parts and service, I'm hoping you might have some information on a permanent or better fix for this motor ? I heard that Bosch used to supply GM with the injector pump but Gm went to another source , which supposedly makes a lesser quality pump.And this last pump only lasted 13 months.

Any help is greatly appreciated.Thanks
