Ok. Is the lift pump functional? Is the filter plugged? Do you have a fuel pressure gauge? http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/49-fuel-pressure-specification-for-bosch-vp44-injection-pumps Did you try to prime the fuel system? http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/90-repriming-a-bosch-vp44-injection-system More ideas here... http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/26-engine-systems/40-basic-diagnostics

If you are bleeding injectors and it still will not start, you need to pull the filter off the airdog and fill them with fresh fuel to prime the pump. I learned this the hard way last week.

Make sure your tank is somewhat full too.

yep when you empty the entire fuel system you got to prime the lift pump or it will just suck air...
