John Deere 6210 Can't prime pump

Plant Doc · Nov 14, 2018

Neighbor has a 6210 with a loader. Back in April his nephew changed the fuel filters and could not get tractor to start. He says he primed the pump according to the manual's directions. Tractor has not been toughed until yesterday when the owner asked me to get it started. I also tried to prime the injector pump but could not get fuel to come out of any injector line. It has an electric fuel pump and there is plenty of fuel coming out of the fuel filter breed and the fuel supply line where it enters the injector pump. I put on a new electric shut off solenoid and still no fuel to injectors. The system is supposed to be self breeding??? It is a little difficult to work on with the after market loader and I really do not want to take the pump off. Is there a screen or filter where the fuel supply line enters the injector pump? Is it possible something in the pump is stuck stopping the fuel flow? Need advice.

Are you sure the fuel control solenoid is getting current?

You will probably have to loosen the injector line nuts then turn it over to get the air out. Did the filters get filled with fuel at changing or not? If not it will definitely take more work to bleed it out. You could try some ether to get it to start saving the battery charge and starter. Don't get carried away with the ether though just whiff it in as it turns over. when it starts let it run for awhile.

Does the pump click when you turn on the key ? can you attach a picture of the pump?

Yes it clicks but not very loud or as loud as I would like to hear. So I put a test light on the solenoid wire and I does have power. The light just indicates it has power, but maybe not enough to activate the solenoid, maybe I should run a jumper wire directly from battery to solenoid. Also, when I replaced the solenoid and had it out of the pump I turned on the electric fuel pump and I did get fuel flow but not as much as I would like to see. ????

I have no way of knowing if the filters were filled when changed, but I bleed the filters and I also took the fuel supply line off the pump and turned on the electric fuel pump, it had a steady stream of fuel. I can't hurt the battery much as it's almost dead, I have heavy jumpers from my diesel pickup which spins the tractor pretty well.

My 5105 got me good one time. I checked for power at the shut off solenoid and had it. What I failed to do was to keep checking for power there as I was cranking the engine over ! Turned out a relay was acting up and the power dropped off when cranking it.

Never thought of that and I will check that as soon as it stops snowing here. Thanks.

I know i always undo nut at each injector and turn over to get air out, do each injector till fluid gets there, tighten them all down. took a long time to get my 4 cyl bled out but started. is that a plastic screw on top of fuel filters to take out , turn over should fill and come out hole. >?
