Just when I finally feel like its running good, disaster strikes, and by that I mean me:
Finished up with the link & sync last weekend, moved onto timing. Timing checked out, but when removing the temporary ground I used to ground the plugs out while checking static timing I forgot to tighten the bolt back up that grounds the panel to the block, when I took the boat out the bolt eventually rattled out completely and the engine died.
Once I got it home I quickly found the ground dangling and reconnected it, though it still would not start. Knowing how sensitive the electrical systems can be I proceeded to check for spark with a spark tester and fuel disconnected, I found that I had no spark on cylinder 2, and a visibly weaker spark on cylinder 4 than 1 and 3. Before I jumped to any conclusions knowing I had some issues with crappy connections and wires breaking off completely at the terminals, I went through and put new spades on every single wire, one terminal at a time as to make sure not to mess up their locations.
After doing this I gained spark on cylinder 2 again, roughly the same as 1 and 3, but did not gain anything on cylinder 4. Still I thought 3 strong sparks and -some- spark on 4 I figured it would at least start even if it didn't run well. I can only get it to very briefly sputter and stall. I have double and triple checked that all wiring is where it belongs.
I am at a loss, seems unlikely to have a completely separate failure at the same time, but I'm open to suggestions?
