I have a 2001 GM3500 towtruck that has a 6.6L turbo diesel. It starts fine idles fine,but when you go to take off it just doesn't go . it is very weak to but will pickup speed eventually than at about 2500 to 3000 rpm it seems to have more power. Someone told me there might be a safety shutdown on power when there is problem with the engine. the engine has 370000 kms on it. it has had new injectors done. any help would be great ron

Make sure all the tubes going from the turbo to the manifold are connected. Had this happen on my uncles dodge once. One of the silicon couplings slid off the inlet tube to the intercooler. This caused a loss in boost and meant no power.

If no help here, surf on over to:

TheDieselPage.com

Part of the site is free, there is a membership fee for full access.

It's WELL worth the price, for any GM diesel owner.
