Hello All,

I got a used automatic transmission in and backed out the bus.
It ran for a while say 20 minutes.
Now it doesn't want to start and run.

I think the tank has gas.  I just got this one running after buying it
a several months ago.
So,, I don't know what all is going on with it.

I just changed the plugs, cap and rotor.

I can hear the fuel pump.

I need a new air filter, and maybe a fuel filter.

Any idea's what to try next?
