    hey everyone im trying to fix a buddy's truck.... the fuel pump went so i change the pump and the inline filter too.... and you can hear the pump working but it wont start..... it has fire.. and there is fuel pressure on the bleeder.. dump a little gas in the TB and it starts... i have done alot of work on these trucks and i have never seen one do this before. i has to be something with the injectors but ont know what... and just for the hell of it i put my scanner on it and i got the wonderful p0300 code, po101, and po420..... so idk

    Are the injectors spraying?

    If that's a Vortec motor, it could easily be that fuel pressure regulator in the injector block. That motor is lousy with those. It costs about $50.

    Agreed, or else you might have a bad filter to.
