the small mechanical lift pump doesnt produce that much pressure... most of it comes from gravity and the little lif tpump helps.. what is your issue? Is it the small bubble in the pre filter

we got the little bit of pressure going to the injection pump but nothing comming out of the lines going to the injectors
now would that be due to a timing issue or a bad injector pump

you mean the hard lines... Is the car starting?

Crack open the injection lines at the injector and crank for 30 second intervals with 2 minute breaks inbetween for the starter to cool.. once you get fuel splurting from the cracked lines at the injectors all air is purged from the lines.. tighten the lines and crank to start..

You've been driving it previously up until the no start? Or is it a new to you vehicle or been sitting a long time?

If driving previously, hows old is the secondary fuel filter?
