im pretty sure mine is shot. the engine is hard to start, but once it starts it runs good. i took the injectors out and checked the spray pattern by hooking them back to the pump and cranking the engine over and all 4 injectors are good but im only getting good enough pressure to crack the injectors on the #4 line. i took the pump off and the fuel cam looks ok. does this sound like a bad pump? the fuel system is full of crud due to the pickup screen in the tank being broke but i would have thought the filter would have caught the majority of it. id like to disassemble the injection pump to check for anything hung up/plugged before i replace it. has anyone ever done this before? any tips?
