I have to spray starter fluid to start it in the morning, it takes a few tries then once started it keeps starting the rest of the day until the next morning.

Good afternoon,

This sounds like the fuel pump is losing its prime and draining back to the tank.

Then it takes a couple of key cycles for it to get to full pressure for it to start.

I would check the fuel pressure before you start it in the morning. then also check it running.

Fuel Pressure (Key "on", Engine "off") .................... 358-405 kPa (52-59 psi)
