  1. Coil is good I do know that. I’m leaning towards crank sensor. I don’t really have what I need to check it I don’t think. I’ve checked and rechecked all connections. The symptoms to me just make sense. I could be wrong though. I removed all covering from harness at plug to where wires go into rear engine cover to the stator and the CKP sensor. No issues found. I did notice it does try to start more when I grab harness at end closes to the harness at the housing and wiggle/move it round. Also tapping on housing where sensor is located it tends to try to fire off more as well. I’m not sure if it’s just coincidence when it does that or really have an issue there. I’m thinking there is. Now I just had this rear cover off due to having to replace final drive shaft getting bent from u-joint coming apart little over a month ago. I started to replace them when I had it off. I’m starting to wish I had. ! I just wish I had some data to look at to know for sure. I don’t want to start throwing parts at something. I despise doing that and don’t practice that in my own shop. I’m undecided at this point as to whether to take to a repair shop or replace crank sensor and see what happens.
  2. It has 12 + volts at black/red wire. Is green wire suppose to have 12 volts or is that the ground? Upon cranking drops to no less 10.5 volts. I’m assuming coil is bad based on these findings. What’s your thoughts?
  3. I only use OE electrical parts on anything. I ordered one from Honda. I did remove all connectors on ECM. Cleaned, applied dielectric grease to every electrical connector. So I have 12 volts at coil is what makes me think coil is bad with having a weak spark. 12 volts is consistent when cranking engine. It tries to fire just won’t fire off.
  4. Well..........since you asked......... in April it sunk in a pond. Upside down tires above the water, floating. Absolutely no water got in the engine. I was shocked. However it is snorkeled. Not even a shot glass of water in air filter box. I was prepared for this cause I knew it was gonna be a battle with some electrical stuff for a little while. I did remove all connectors and electrical components right away and dry everything out as best I could. It’s been small things here and there last few months but nothing real major till last month when I had to replace everything from final drive, rear diff, every single little bearing and seal along the way. I mean I replaced everything. Only thing I didn’t replace was stator and CKP sensor while I had rear cover off. I kinda almost regret doing so. I’m wondering if CKP sensor maybe an issue to being spark is just hit/miss and not consistent. FYI...... to my knowledge he hasn’t been in any water since then due to it scared him so bad.

  6. That I did do. Yes NGK plug only. Even tried a bee for the ! of it. Even removed all connectors to clean and reconnect. I’m not real good with in depth electrical diagnosis. Not having any data to read is killing me. A good majority of it I can handle with no problem. I handle more of mechanical type repairs/rebuilds. I don’t get my ! kicked very often but this just has me stumped. Anyway, from Ive checked with my volt meter as best I can it seems maybe the ignition coil might be bad. I’m not 💯 on this but I’ve ordered one to pick up tomorrow and see what happens. If that don’t do it I’m gonna take it to the dealer for repair most likely.
  7. Couple days ago son was riding and unit just died. Spit sputtered and died. So I get to checking stuff. Here fuel pump coming on. Decided to remove pump and inspect anyway. It was nasty. Fuel was jet black and sock appeared to be stopped up. So i replaced pump due to that and never been replaced. Thought it was a fuel delivery issue. Got fuel spraying at injector really good. That night checking it out before replacing pump it wanted to back fire a lot with using starting fluid. It will try to start at times and dies immediately. I did replace spark plug for ! of it as well. So today while trying to figure this out I removed spark plug and watched it during while trying to crank. Spark is very inconsistent (hit and miss) while cranking and kind of a bright orange. I’m thinking it has a weak spark. What could cause this other than ignition coil? I don’t think it’s jumped time being when it does start briefly engine sounds ok and no noises.
