I bought a new long block for my '93 GMC. I've been having problems greeting enough fuel to the Inj. pump. Ive checked my oil pressure switch and in stalled a new lift pump. I still can't get enough fuel to the injectors to fill the return line or even to bleed the injectors. So I bought a rebuilt Inj pump and a new set of injectors. The old pump had over 150k on it so....it was time anyways. My problem is that the timing chain cover doesn't have a timing mark ti set the pump. Is the mouning stud top dead zero? Or is the corner that comes out on the drivers side zero... or is it somewhere in the middle? I already sent my old block back. HELP!!!!!
