Hello
Ive been scratching my head over this one. 1995 5.7 with 4bbl carb and thunderbolt ignition. I am not too familiar with these things but I still am surprised why it won't run. The boat ran fine last week. This time it cranks and intermittently fires, but won't run. The accelerator pump shoots a good stream of gas into the primaries when the throttle is pumped. Tried putting gas into the carb manually, no change. Checked for spark with a timing light and nothing. Checked for power at the purple wire on the coil, also nothing. There was power at the ignition switch, so I bypassed the kill switch, and now I have power at the coil and spark. I thought I had nailed it now, but it still won't start, won't even fire. Tried adding gas to the carb again, no dice. Tried holding the throttle wide open to clear a flooded engine, it fired once and nothing again. Thinking that the flood was now clear, I gave the throttle a couple of pumps and tried again, still nothing. Checked for spark and it is still there. I need some ideas.
Thanks!
