Any body know any thing about 2000 GMC SAVANA 3500 Diesel van that stalled at no appear reason while driven. I just bough 2000 GMC SAVANA diesel van 6.5Lt I drove for 1.5 hrs at 70ph Van stalled I shifted gear to "N" then beable to started again. Yesterday, I drove about 21 miles it stalled on me again.
Here's the list of common items that cause stalling in the 6.5L motor, from cheapest to most expensive:
Water in fuel - drain you fuel/water seperator
Clogged fuel filter - replace filter
Weak tranfer pump (moves fuel from tank to fuel injection pump) - check flow rate and pressure
Failing fuel solenoid driver (FSD, aka pump mounted driver/PMD and is the black box that controls the fuel injection pump) - replace FSD and add an aftermarket FSD cooler. The FSD is the weak link in these motors but an FSD cooler goes a long way to alleviating the problem.
Failing fuel injection pump - rebuild/replace the entire pump and add an aftermarket FSD cooler.

The first thing to do in any fuel related issue is drain the fuel/water seperator and replace the filter. It's quick and cheap.
