First time posting. I have a JD 5205 that I purchased last fall with about 800hrs. After purchasing I did some bush hogging at a piece of property I own. I didn't have anywhere to store it during the winter so it sat parked outdoors for about 5 months without being used (in south MS). Time came this spring to bust it off and start mowing again but it wouldn't crank. Engine is turning over without any issue but it wouldn't fire up.
I've bled the fuel system. I went ahead and changed the fuel/water filter. I disconnected the line going into the fuel pump and I'm getting plenty of fuel to the injector pump but it still will not crank. I cracked the lines coming out of the injector pump and I'm getting almost nothing. Just a few bubbly drips coming out of the fuel pump when cranking on it. I'm getting just under 12 volts to the injection pump. I've tried disconnecting the cold start thermistor (sp) and nothing seemed to change. Is there any other type of sensor that could be malfunctioning that would disable the injection pump even though it's showing 12 volts to the main electrical input coming into the pump itself?
I went through the step by step to bleed the fuel system. crack the return line, open the filter bleeder, pump pump pump till no bubbles. crack the injection pump bleeder, pump pump pump but I'm not getting much fuel coming out of the bleeder on the injection pump. Nothing like what I'm getting at the fuel filter where it gushes out with every pump.
My father and I gave up earlier today and were convinced the injection pump has suddenly gone bad for no apparent reason. From what I gather that's about a $1500 part from JD + labor to install. Hoping and praying that's not the case. To me it's got to either be a bad pump or some type of sensor that's keeping the pump from pumping.
Please let me know if there are any other steps or things to try before throwing in the towel and dragging it to the JD stealership. Thanks in advance for any help and I hope everyone is having a happy 4th!
