Pressure should be around 55psi. Make sure you have fuel and spark to the engine.

Is the pressure within spec? Are you getting a good hot blue snapping spark to the plugs?

The yellow spark doesn't sound good. That is a weak spark. You may have a problem with the crank sensor, coil, ignition module.
