Yamaha's are a bit cold blooded. Determine if it's compression, ignition or fuel. If your compression is good, next try a shot of starting fluid into the air cleaner, only use a bit and shoot some in while turning the starter or have someone shoot some in and kick it over immediately. If it starts or at least shows some life, your problem is in the fuel supply or carb. 60% of troubles I see is due to modern day crappy gas. Never use fuel with alcohol (oxygenated) and do not use gas more than 90 days old unless it was treated with a stabilizer.
Next step is check your spark. I prefer using an old spark plug gapped wide, say .040, and clamp it with a hose clamp to a battery charger alligator clamp to ground to the engine. You should see a consistent blue spark. If you have electric start, spin the motor for say 30 seconds and feel the heavy positive that goes to the starter, or the heavy ground. If it feels warm and/or if your starter doesn't smoothly turn over, a bad starter can take power away from the ignition.

===========





Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Self start problem


Your starting problem may be battery charge level. Take buy a auto parts store, most will measure the battery charge condition and may recommend a new battery, They will also measure the status of the charging system, which if not adequate, will contribute to the poor battery charge and starting problem. If the battery condition is good or very good, you may have a Starter solenoid or starter and solenoid problem.

It could be a problem with the fuel pump or igntion module/ coil pack. The next time it stops, fuel pressure needs to be checked and have the ignition coil pack and module tested at a local parts store.

Sounds like a bad connection problem at the items you're moving around to finally get the car started. Read what you actually wrote. You'll see that you answered your own question. Start by confirming the connections at the items you're moving around.

GMC Safari start problem


I think it's the fuel pump or the fuel pump filter.

Check the fuel system that's where your problem is, my bet is your fuel pump has left this world to a better place.
