JD 445 fuel pump/ignition problems

Jerry	08/16/09 A couple of days ago, while mowing ,running at full rpm, my 2001 445 lost power for 1 to 1 1/2 seconds, backfired and continued running for 5 to 10 seconds then quit completely. Tried several times under numerous conditions to restart and it would not. Engine turns over but no ignition. Checked spark and though bright daylight, saw none. Sprayed small amount of gas into cylinder to see if fuel problem and did not get any ignition, however, cannot hear fuel pump run at all when switch is first turned on. Started electrical trouble shooting by checking all fuses, F5 power, F4 lights and F3 fuelpump fuse and all are OK. Checked voltage at connector going into fuel pump and coming out of fuel pump relay and all seems OK. I originally thought it was not getting fire to spark plugs but not sure if it is fuel or ignition problem or other. Any ideas?? Thanks for all help, Jerry
Jerry	08/17/09 As a followup, I rechecked the spark at the plug, removed it from the cylinder head and attached a clip from body threads direct to battery ground, cranked for a couple of seconds and NO SPARK. This time, cloudy overhead so could see good. I removed the gas line going to the fuel injection body and turned on the key switch to see if gas were being pumped,NO GAS comes out of the fuel line. What are the odds the fuel pump will go bad and the spark plug firing system will go bad at the same time? Am I overlooking something? Thanks for any and all help. Jerry
nipper	I have the same problem my fuel pump does work but no spark. looking for a schematic for elec. system. can any one help?
Adrian Johnson	I also am having the same problems mine is a all wheel steer tractor with kawasaki engine 535 hrs bought used worked good to start with last year but does same thing I can be mowing and everything going good and it will sputter and try to run and like that just like it shuts itself off very frustrating to say least usually if I turn ignition on and off two or 3 times it will take off again I found that if gas tank is full problem seems to go away for while I think it is the fuel pump and in talking to one mechanic told me sometimes the inlet connection inside the tank can suck air and cut fuel supply to engine unfortunate part the fuel pump is in fuel tank and you need to remove the fender housing and tank to see, new fuel pump is about $400.00 am thinking of removing tank investigating the connection part and if it seeems good probably will bite bullet install new pump and see if that takes care of problem! any suggestions or light that could be shed will be appreciated. I relly like this unit and was pricing new ones and that is not an option for me!any help will be appreciated!Adrian J.
Rob	might want to check the fuel lines in the tank. I've searching about my own problems and what you guys are describing sounds familiar. Apparently there is a 5" pice of black hose connected to the pump, and this hose gets brittle and cracks. I hope this helps. Rob
