So at this point I feel like the little Dutch boy with my finger in the dam. First started with a rod knock, fixed that. Then bad spark plugs, replaced those, swapped out the injectors and a new fuel rail. Now the poor thing won't actually get combustion. It tries and the crank moves, the timing is good last I checked but after about 5-10seconds trying, all the lights begin flickering the battery drops below 9volts (seems to rest at roughly 8.2v) the continues for a couple seconds the everything shuts off and i just get a clicking from the starter. Any ideas or at least a place to start looking?
