Little back story on myself and bike to help you help me.
MYSELF- I am a mechanic at a powersports shop here in Tn. I'm also an automotive tech (retired) with over 15 turning on cars, boats, pwc, atv's so im fairly knowledgeable and we rounded with my mechanical ability. That being said, i also know i have a lot to learn after being out of this industry for the last 8-9 years.
THE BIKE- 2008 ZX-10R with 7k miles. Bike was purchased a couple years ago wrecked by another mechanic where im currently working. All plastics, subframe, wheels, radiator and a laundry list of brackets and supports have been purchased to rebuild this bike (shop had around $4k invested in parts alone) before i decided to purchase the bike and tackle the problem. (What i know from previous mechanic) Bike ran when bought but was in bad shape and not anywhere near street-able. Everything was purchased to build , bike was put together, running and ready to ride/sell. They decided to put new sprockets and chain on it and everything went south from there. Apparently a young apprentice decide to beat the sprocket or something on with a hammer and the bike would no longer shift after that. The bike was then tore down due to a shift fork being bent. Shift fork replaced and transmission rebuilt and bike goes back together again. Somewhere in the process the the ecm was lost so a new(used ecm) was purchased which has landed me where i am today. NO SPARK. Fuel pump primes, gages all appear to work but F.I light is on. Checked codes and im getting code 21(crank sensor) im fairly positive that i have everything hooked up and in place but might have missed something. Previous mechanic had several codes and had replaced the tip over sensor , wire harness and ignition system (key). I have a manual and have yet to really search for information as i have not had a lot of time to spend on this bike. I'm sure eventually i'll get it figured out but figured i'd jump on here and ask some questions to help me streamline my searches.
QUESTIONS-
1- Can the FI light be reset or does it reset itself when problem is fixed? Also how do you pull mutiple codes if present? I've only been able to get the 1 code and havent figured out how to toggle to other codes if there are any
2. What controls spark or prevents spark? I know some machines will get signal from crank/cam sensors but if lets say if its not getting proper reading from neutral switch it will not allow spark but will allow it to turn over. (neutral -crank- cam was just an example, no clue how this thing is wired)
3. Is it possible that the ecu is bad and can it be reflashed? someone on here reflash or have a good ecu laying around for sale?
4. Given the symptoms if described, any of you guys that work on these bikes regularly have a direction for me to start checking before i start dropping more money on good parts that dont need replaced. Not real excited on have $10k wrapped up in a $5k bike lol
I thank any and everybody in advanced for any kind of input (unless you try to explain how cleaning the carb would be a possible solution for my no spark issue lol) you can give me on this post.
