almost sounds like a bad fuel pump ?, or fuel relay ?.
2014 honda rancher won't start
Ok I have a 2014 honda rancher 420 4x4 foot shift. I bought it knowing it wasn't running and the guy said its a bad or stuck open injector. I pulled the injector off and turned the key and fuel was dumping out of the fuel line. put the injector on the fuel line and it was spraying when I hit the start button. Changed the spark plug and it was getting plenty of spark. I have a second 420 that I took the ECM and mass air low sensor and O2 sensor off of the bike and didn't change anything. It will sputter when you try and start it while hitting the throttle so I think it something simple but not sure. I am new to EFI so I am looking for some help. Carbs are definitely easier to work on but on to EFI.
Thanks,
Hunter

first, never put the cam on top dead center !!!...lol. you want the PISTON on top dead center on the compression stroke !!. second, there is a sticky in the repair section on how to set and adjust valves, read it, READ IT AGAIN..understand it !!. this will make your life sooooooo much easier.
you don't need a timing light. all you need to do is follow the sticky on how to set and adjust valves on any 4 stroke in the repair section, if you follow that ?, then its home free.ok well this is probably a stupid question but I looked up ignition timing in the service manual and it showed using a timing light and having the bike running but how would I check that if its not running. Is it checking the coil or what? im just new to some of these electrical things so im trying to avoid messing up
yes, I know what he was asking, but if you look at the sticky, it covers everything on how to set the timing marks, you don't need a timing light if your setting valves, setting valves is the same thing as setting all the timing marks, i've done this thousands of times, I know what I told himHe was inquiring about setting the ignition timing, not the valve timing. To use a timing light on an engine that isn't running, just turn the engine over with the starter while using the timing light.you don't need a timing light. all you need to do is follow the sticky on how to set and adjust valves on any 4 stroke in the repair section, if you follow that ?, then its home free.ok well this is probably a stupid question but I looked up ignition timing in the service manual and it showed using a timing light and having the bike running but how would I check that if its not running.

why does he need a timing light to check the ignition timing ?, there are timing marks everywhere on that motor, if he sets the marks, sight hole, rear crank case, piston on top dead center on the compression stroke ( which can be checked by the sticky on how to set and adjust valves ) , you don't need to crank anything over with the starter. I have never used a timing light to check ignition on an atv, I go by the timing marks, valves set on the compression stroke, bam..running engine !..lol.IF the compression test is within spec (if not stop right there and fix it), then check the ignition timing using a timing light while cranking the motor over with the starter. The service manual shows you how to do it through the timing access plug. If it looks like its out slightly, suspect that the woodruff key is sheared on the flywheel.
correct me if I am wrong ?, but if the T mark on the flywheel, and the raised arrow behind the starter cage don't line up ?, then your right, the flywheel woodruff key can be sheared ?, but if these two marks line up ?, then he has other issues.Because we are not talking about checking valve timing, we are talking about ignition timing possibly being out because of a sheared flywheel woodruff key. You can't check the ignition timing any other way, the motor has to be spinning.why does he need a timing light to check the ignition timing ?, there are timing marks everywhere on that motor, if he sets the marks, sight hole, rear crank case, piston on top dead center on the compression stroke ( which can be checked by the sticky on how to set and adjust valves ) , you don't need to crank anything over with the starter.

deff agree on this ^^^.Anyway, the compression test needs to be done first. If compression is low the ignition timing is obviously irrelevant. This is the logical order of every no-start diagnosis after spark and fuel are verified.
yeah, I seen your trying to get him to do a compression test. you don't need the motor part to check these two timing marks ?, both are easy to get to. anyway..i'll leave this for you and himBecause he does not have the motor taken apart, this is the diagnosis stage... a timing light is the best tool (and quickest) for this job.correct me if I am wrong ?, but if the T mark on the flywheel, and the raised arrow behind the starter cage don't line up ?, then your right, the flywheel woodruff key can be sheared ?, but if these two marks line up ?, then he has other issues.Because we are not talking about checking valve timing, we are talking about ignition timing possibly being out because of a sheared flywheel woodruff key.

I've been trying to get him to check the compression for 3 days now, but he wants to talk about all of these other things first, so thats why we are explaining them.
