This is on my 2002 620.
Turn the key to on, fuel pump cycles and gauges sweep. I just got the gauges, etc. back from being reprogrammed so the immobilizer works fine. When I push the start button, nothing happens. Sidestand is up and it's in neutral.
Now, If i jump the solenoid the bike starts and runs but only with the choke fully out and the check engine light is lit.
I replaced the solenoid today and that wasn't the problem.
Any suggestions???
check to see if the electrical connector going to the tank is connected correctly, if that gets loose you will hear the fuel pumps and th gauges will sweep but nothing happens, no cranking.
check to see if the grounding wire is connected good.
if all else fails turn the bike off try again, and if that doesn't work, turn it off let it sit for 5 min try again, for some reason sometimes that worked with mine, why? i have no idea.
but i do know that the grounded wire from that connector had some issues with mine and i had my mechanic resoder some of the wires there and now its not an issue anymore.

thanks for the quick reply. I tried your suggestions and nothing. Is there a way to test the starter relay? Could that cause this problem?
Isn't there a fuel level sensor problem with these newer bikes that relates to the inability to get them started? Doesn't the computer say "Woah Nelly" when it thinks you don't have enough gas to run safely? Or am I thinking of something else?
A bad solenoid can prevent the bike from cranking, but it will not affect the running of the bike once started. OK, a stuck closed relay will cause the starter to stay engaged after starting. The check engine light means you have a fault in the engine management system. My guess is whatever fault is being detected is preventing the signal from the ECU to the solenoid, or, as Hedgehog said "Woah Nelly". I never heard of a fuel level sensor problem causing a no start condition, but it sure sounds like what sbrguy is describing.
Anyhow, checking the solenoid is easy. There is a white connector on the back with two small terminals. Offhand I don't know the wire colors, but one is hot, one is ground. Unfortunately I am not sure how the computer activates the solenoid, so, unless someone else with more knowledge gives better instructions, remove the connector, 12V direct to one small connector, ground to the other. The bike should now crank. Do make sure the bike is in neutral.
I replaced the solenoid with a new one and I still have the same issue. ???
Fuses? Safety Relay?
fuses are fine. What do you mean by safety relay?
Not sure if this is the same with the newer bikes, but I had a problem on my 01 m600 that sounded similar to your issue. There are three black relay boxes underneath the seat...not sure what you'll find under yours. But one of the boxes, the smallest I believe, is the relay for your kickstand (it cuts the bike off when you put the kickstand down in gear). I ended up bypassing that relay using a paperclip and my bike fired right up, so then I found a bunch of compatible relays from an auto parts store and replaced it and have had no problems since. Like I said, this might not even be close to your problem, since I am not familiar with the newer bikes. But its a quick thing to check for.
No safety relay. That function is handled by the computer. Again, there is a fault in the engine management system and the solenoid will not cause running problems. Sorry to say, but the best solution is get the bike over to someone who has the diagnostic equipment and go from there.
Ok, no relay on the newer models, sorry OP.
