    thanks for the information from kohler. im reading the service manual and its leading me taward a fuel issue..i will have to troubleshoot and test all components of fuel system and go from there.. one more thing? why whould my over temperature warning light come on when my engine is cold? and do you think the warning alarm went off due to the service engine soon light being on due to the fuel issue?

    I think most "Idiot Lights" come on initially to indicate they are working and the bulb is not blown, and go out once the engine is started.

    The first place, in my opinion, you should start is to give your Carburetor a good cleaning. Remove, disassemble, and clean thoroughly inside, with Carburetor/Choke cleaning solvent.

    This is an EFI engine which utilizes fuel injectors and does not use a carb for fuel delivery. Check the fuse for the electric fuel pump first. Sometimes, its the simple things that cause fuel problems.

    Did it run out of gas? If it did then your gonna have to pull the clamp off of the fuel line and put gas into it so that the injectors can suck it into the motor. You may have to do it a couple of times, it takes awhile. If it didnt run out of gas then you have an air leak somewhere and the motor is sucking in air, but I will bet if you disconnect the fuel line and continue to put gas in the line then try and crank it, it will eventually start. If you try and crank it to much though it will continue to suck in air and make it that much harder to start.

    Could it be a circuit board or a bad connection making the thing go haywire?

    Because that's the only thing I can figure, all them lights coming on and then the mower not starting...

    I'd certainly second the recommendation of checking first the fuses, and relays if it has.

    You should hear the fuel pump prime it's self when the key is fisrt turned on. It will then stop after a few seconds. Is it doing that?

    the mower did run out of gas and yes the fuel pump comes for a second then shuts off once the fuel system is presurized..im going to disconect the line from fuel filter and hook it up to a seperete container and see if it cranks over with fresh fuel.. i'll give that a shot tomarrow...thanks guys
