2001 monster 750 died on me and won’t start

[Motopsycho Mike]

Had just got done filling the tank, put it in first and started to release the throttle and it just died. Since then when I try to start it up absolutely nothing happens. It doesn't crank or click like it would with a dead battery. No sound at all.  The battery is tested and good. Lights all come on. I sparked the selenoid and it runs for maybe 2 minutes and then dies and I'm back to the same problem. Any ideas??

Thanks,
Mike

It seems you have two problems.

Not cranking when you hit the starter button is likely the small white connector on the solenoid. Unplug it and plug it back in.

Quitting after a couple of minutes is a different issue.

[Motopsycho Mike]

Yeah...  already tried disconnecting and reconnecting the selenoid. Same problem. I just can't figure out what to troubleshoot next

If you bridged the solenoid and it cranked after fixing the little white plug then its probably the solenoid. Starter motors are pretty robust.


Now to check for fuel flow. Pinched breather hose when lowering tank? Failed vacuum tap under tank? Open fuel cap  rush of air? Open the float bowl drain (screw on bowl near small hose), any fuel come out the overflow hose?

[Motopsycho Mike]

I'll give those a check this weekend. Thanks for the tips. I'll derby what I find

Also, when was the fuel filter last changed?

Many threads here about those vacuum taps giving lots of trouble and the advice here is to remove it and plug the manifold vacuum fitting, then fit an in line manual tap like a Motion Pro or Briggs and Stratton tap you can reach easily while riding. Get an Ethanol resistant tap if you have that curse in your area.

One white connector at the solenoid has a red wire with a black stripe.  That one is hot key on, starter button pushed.  The other is black.  That one is ground.   If the ground is good and the R/B wire is hot when you press the starter button and the solenoid connections on the big wires are clean replace the solenoid.

No power at the R/B wire?   Remove the main relay.  Check for power at terminal 30 (brown wire).  Take a jumper wire and go from 30 to 87.  Bike start now?  Replace relay.

Not sure if this is helpful but symptoms seem similar: last November I had just gotten off the highway when bike sputtered and died.  No crank/click so I immediately guessed it was a broken wire by the steering column.  Sure enough it was a broken wire but what surprised me was that while holding wires together she started/ran but letting go engine died.  Took subway home to get tools but drove home.  One of the brown wires broke on me last week but engine ran without continuously holding them together.
