Recently I was working on a 08 Chevy Suburban with a VIN 3 5.3 ( LC9 ) engine. This vehicle uses a fuel pump flow control module, however there is no option for this module in the data main menu on my Verus (10.2 ). An 07 Suburban uses the same VIN 3 engine without the pump module so maybe this was over looked in the 08 ? Or corrected for 10.4 ? The 07 and 08 Silverado with a VIN M ( LH6 ) also uses the pump module and the there is a separate fuel pump module option in the main menu for data and some function controls as well .
