SUZUKI MOTORS HAVE A SECONDARY POWER WIRE THE PWERS TEH ECM SEPERATELY.
IT WILL COME OUT OF THE RIGGING TUBE AND LOOK JUST LIKE A SPEEDO HOSE
IT IS A #10ISH WHITE WIRE COVERED WITH A BLACK PLASTIC SLEEVE.
IT SHOULD GO DIRECTLY TO THE BATTERY OR PERKO SWITCH.
IT WILL HAVE A BLADE FUSE AND HOLDER.
CHECK THAT WIRE FOR POWER.
WITHOUT POWER TO THAT, THE TILT TRIM ON THE MOTOR WILL WORK, THE MOTOR JUST WONT TURN OVER.
Try tapping the starter with a rubber mallet or a block of wood while somebody holds the key start to on. May kick it over.
Just passing this along for chevy fans. This method will “sometimes” work as well for a failing fuel pump on them. Use the rubber mallet to hit the fuel tank with the key on. Might get you back home.
As for the starter, if that did get it to “kick” over I’d soon replace it as internal bearings/bushing are failing causing the stator to hang on the magnets or your brushes are shot.
