455 doesn't want to start. I have already looked at all 3-fuses and they appear to be ok. The float ring in sediment bowl at the injector pump is not visible and has fuel in it. When I turn the key on the shut off solenoid operates - it pulls back for a couple seconds and then appears to close partially (throttle is down in the idle position). I believe my next step will be to pull off the sediment bowl and empty it out. Then I will put it back on and turn on the key to verify the fuel pump in the fuel tank is operating before I pull off the seat and the rear shroud to pull the fuel pump to see about a fuel filter there. The only other thing will be maybe changing out the spark plug before I decide to call Mother Deere. The motor turns over just fine and usually after just a second or two it fires right off - but not now. Should I be investigating something else? Thanks in advance!
