there is a injector driver module relocation kit with a heat sink to mount it to because the module in the orgional location the module would overheat. also check the glow plugs the quick easy way to do this without removing them is to unplug all the glow plugs then hook a jumper wire up to battery positive and and touch it to each glow plug there should be a spark and if there isn't then the glow plug is bad.

check for vacuum leaks at throttle body gasket. pvc valve stuck open.if all is good .change fuel filter .if still stall out check fuel pump pressure.if all is good .replace plugs and wires if they have not been changed.

The fuel pressure valve is stuck open and drains the fuel (via gravity) back to the tank.
Check the fuel pressure regulator / replace.
You might want to put a bottle of "complete fuel system" cleaner ($8 AutoZone) in the gas (not diesel) tank, next fill-up. It may do the trick in a couple of days.
