Question about 1992 Dodge Grand Caravan
SOURCE: dodge diesel lost its prime!
You have to loosen your injector lines one at a time and have someone crank the engine. once you get fuel to that injector,tighten it and move onto the next one. This will be a lengthy process and make sure you have good batteries cause this process could drain them. Good luck

Well, one problem is, if its an 8.1, its not a diesel. The 8.1, or Vortec 8100, is a gas engine. The DuraMax is a 6.6 engine. There is usually not a priming system on a gas engine, because the fuel pumps will usually get it through the smaller filters used quick enough you dont need them. However, if it is a DuraMax engine, then right on top of the fitting where you mount your diesel filter, there is a primer pump and an air bleed valve. What you do is, open up that air bleed valve ( its a little black plastic octagon shaped thing on the top of the filter mount) then you pump the primer (the silver button looking thing) until you get diesel squiting out the air vent without too many air bubbles or gurgles.

I suspect your fuel filter is clogged. This often happens after you run out of gas because your engine sucks up all the gas in the bottom of the tank where dirt and debris have been collecting for years. I recommend changing your fuel filter and if that doesn't fix your problem, try adding some fuel injector cleaner to your gas.

Its normal for the pump to run for three seconds then shut off if the car engine is off. . This indicates that the fuel pump turned on and the pressure did reach specifications. If the pump did not reach pressure the pump would continue to run, You need to check for proper pressure with a gauge. If tthe pressure is ok then you have another issue like an ignition module or crank sensor if applicable. You may have to drive the car with the fuel gauge hooked up to see if you still have pressure when it dies.. I know you said you replaced the pump already but do you have the same issues as before you replaced it. This would indicate which direction you need to go now. If the same then its prabably not the pump.

Your fuel injector rails should have a pressure release valve somewhere. Pressure needs to be released. Watch out for flying fuel though!!!
