gizmozg Posted August 18, 2023 Author Share Posted August 18, 2023 FTECU told me to clear the codes and try dumping back the stock map from their tune. We shall see what this does this weekend. 1 Link to comment Share on other sites More sharing options...
shinyribs Posted August 18, 2023 Share Posted August 18, 2023 What do those codes represent? The bike is probably trying to tell you what's wrong, but you have to look up the codes. Link to comment Share on other sites More sharing options...
shinyribs Posted August 18, 2023 Share Posted August 18, 2023 Took me this long to Google "FZ 07 sd code list. 13&14 are air intake sensor. 41 is tip over sensor. Reinstall those devices in their proper orientation and try again. If they are installed properly, double check your pin installation of the bike side harness.

Triple Jim Posted August 18, 2023 Share Posted August 18, 2023 (edited) Here's a list of codes. The ones in question are 12, 13, and 41... crankshaft position, air intake, and lean angle. https://www.reddit.com/r/FZ07/comments/498d71/fz07_error_code_list/ Edited August 18, 2023 by Triple Jim Link to comment Share on other sites More sharing options...

gizmozg Posted August 24, 2023 Author Share Posted August 24, 2023 I did find all the codes already, bike is stripped all the way. Lean angle sensor is good, crankshaft sensor is good, the relays are good, now its fuel pump testing. Just pulled the tank off and tested the pump, makes barely any noise when connected to 12V and no fuel coming out at all. Should it not send out fuel with it primes ?

Went back and reflashed with stock ecu map and still got the same issue. I am no expert on flashed ECU - but it almost sounds like somewhere in the process a fuse or something got blown. Restoring the stock ECU map should have remedied any changes, but it didn't. Just looking at the super simple basic stuff, what happens if you pull the air filter and spray starter fluid as you crank it? It should at least briefly run (unless open circuit somewhere). I would test that before going deep on a fuel pump (to isolate fuel vs spark being the culprit). Also, with repeated attempts to crank an engine that would not start, I would charge the battery to the point of a strong 13 volts because a marginal battery can cause all kinds of grief.

Yeah, battery change is on my mind for sure. it had 12.3V yesterday. Fuel pump connected to it did not send out any fuel or make a sound last night. Bigger issue is that 2 ODBII readers did not connect to the bike so i cant even try to clear the codes Link to comment Share on other sites More sharing options...

It seems that Yamaha is doing something non-standard. Link to comment Share on other sites More sharing options...

Do you have a charger? Even a battery that is circling the drain will usually take a charge (even if it doesn't hold it very long). A weak battery will use all it's amps cranking the engine & you may get a weak spark. Given your sequence of events, I don't think that is the CAUSE of your issue but it will be very frustrating if it complicates the troubleshooting by adding another variable after repeated cranking without starting.

Triple Jim Posted August 25, 2023 Share Posted August 25, 2023 The battery voltage during cranking is most important. You should see something near 10v while cranking. Some sources say that below 9.6v indicates a failing battery. Link to comment Share on other sites More sharing options...
gizmozg Posted August 25, 2023 Author Share Posted August 25, 2023 I did top it off day 2 of troubleshooting and tried from there, it was at 12.7V then. I can always get a new battery, probably need a new one. Link to comment Share on other sites More sharing options...
gizmozg Posted December 11, 2023 Author Share Posted December 11, 2023 Still having issues with the bike. Its been a few months now and still in the same spot. Fuel pump is good, debating buying a used ecu Went to a local Yamaha authorized service center and they told me they wont work on the bike cause its tuned. Only way they would look at it is if i buy a $700 stock ECU for it then the repairs would start..... Spraying starter fluid into the air intake did not crank the bike as well. Should i pull the coils out ? Link to comment Share on other sites More sharing options...
ElGonzales Posted December 12, 2023 Share Posted December 12, 2023 FZ / MT 07 VERY IMPORTANT: Please make sure you are flashing the correct file! Quote You will need to "reset" your ECU by flashing our specific reset file into your ECU first, then flashing a new correct file immediately afterward. Have you followed these instructions?
