Starter flywheel is not engaging motor

Sometimes I take the starter motor off the vehicle. Lay it on the ground, hook up jumper cables properly from battery to starter motor, it should do two things, kick out the drive gear and spin. Do you have a flywheel cover that you can remove and watch the starter drive gear engage the flywheel? Also, check the flywheel teeth.

Could the battery be dead? No turnover often means dead battery. 2008 truck with original battery, time to replace it.

Okay it says you checked starter motor and it tested good. what test did you perform? A bench test would tell you if solenoid is good or bad. Try this With starter in vehicle and key on, jump positive power to solenoid it should spin and engage flywheel and start vehicle

if your battery is low on charge or you have to jump it off it may already be engaged and stuck in flywheel try turning motor by hand back and forth listen if you hear it pop out then try to start with good battery if doesnt work replace starter it could be the selinoid switch but you have to pull starter anyway so just replace all of it

MOST LAWN TRACTORS DO NOT HAVE A FUSE BOX. SEE IF THERE MAY BE A IN-LINE FUSE.

Your battery is to low on power it needs a good charge, or replace it is the best option for a brand new one!

I would start by ensuring that the battery is fully charged, and that all the battery and starter connections are clean and tight. If the problem persists, the starter solenoid is probably faulty.

sound like fuel delivery problem if it starts and shuts off also you don't jump these cars from the battery there are special posts if you try jumping at battery could cause voltage surge on ecm and fry it that is about a 1500 dollar replacement part

check the starter see if it is going bad or not?

make sure your battery is not dead
