cant get it to fire with out starting fluid. I replaced both filters, and visualy inspected for pressure at the pulse damp. having a bitch of a time finding much less borrowing a fuel pressure tester with an 8mm banjo fitting. so I'm just kinda wondering what I should do next? not trust the pump and replace it or try and clean the injectors if such a thing is possible. or pony up and buy the tester off the internet?
