Fuel pump problems on a 200 AC

If it's been sitting for a while, especially if the fuel in it is old, the pump may be gummed up and will not pump fuel. Best fix is to have it properly serviced. 

Might of just seized and sheared the key on the drive shaft. My 220 did that once. Take the little cover off the side of the pump (2 screws) and see if its turning when cranking the engine. There's 2 little timing marks there. One moves the other is stationary. Also try taking the return line AND FITTING off the top of the pump and try to start it. If it starts the flex ring inside is coming apart. Either way you'll need a rebuild.

Sorry no it didn't.

Katahdingirl, you did the right thing by jumping on this forum and seeking help. These guys know a bunch about these tractors and they helped me out with my failed Injection Pump. I do believe I encountered the more common problem of the slow disintegration of the internals of the pump, which caused it to work sometimes and other times to not work. Should be easy for you to determine if the pump is advancing or not when the engine turns. Of course, diagnosing and installing and reinstalling the pump in the field sucks, so if you decide to pull it back to the barn, it can be tricky. Without the engine running, you have no steering, so you have to go slow. I believe you want to put the power director in neutral as well when pulling. I pulled mine about 400 yards extremely slow and had to adjust the tow strap as the tractor decided to go wherever it wanted. It was not recommended by members to pull it miles though to avoid transmission issues, even if you could do it safely. InjPumpEd rebuilt my pump and he does great work and turns it around fairly quickly, but it is still realistically a good 10 days. If you have something else like a broken shaft, then you may have a bigger problem. I am guessing you might as well deinstall the pump at this point unless you see upon further testing that it is turning as the engine cranks. I have a detailed post on this forum on the process I went through to take pump off and reinstall on my 190XT which is similar to the 200. Lining up your timing marks, is probably not possible by the description of the problem. You should score the position of the pump to the mounting plate to insure that you get it back where it was since it was running fine in that position. The biggest problem I had was folding back the seals on shaft on the reinstall which ran diesel fuel into the crankcase. If it happens, then you just have to start over. Sorry for your bad luck but please report back on your status. We always want to help new members!
