Howdy folks, I just bougth this Zetor and it was starting and running great when I tried it and when it was delivered. It has the verticle muffler because of its front end loader and after I parked it, it is possible that maybe an inch of rain water ran down into it. I went to install a raincap and try to turn it on, but no luck, no smoke, but it did turn over. I lossened the back three injector lines and found no fuel going to them while cranking. I ordered the owners and shop manual for it and it showed how to purge air out of the fuel system by removing the bolt on top of the front of the injection pump and inserting the ignition key in. I did this and still no fuel going to injectors. I also did notice that upon pressing the hand pump there was hissing on the injector pump side withhout a hose clamp so I installed a hose clamp and it stopped the hissing, but when I pump it the glass filter shows some air and then appears to get full of fuel again.Please advise. Thank You
