I believe it might have a leak, or possibly a leak in the injector's plastic lines. It's hard to start after it's been sitting awhile. With a shot of ether or continuous cranking it'll start and run fine all day. It has a new fuel pump, filter, cap, rotor, ignition mod, wires, o2 sensors. Maybe the pump is bad also.?
