I suspect that there is ice in the pump from moisture in the old fuel. For one reason or another, the fuel pump is not delivering enough pressure for the engine to fire. So therein lies my problem with the fuel system. If the pump is working as it should, fuel should spray everywhere due to the pressure. However, with the fuel line (that goes to the injectors) off the pump, I tried to crank the engine.
#Fan 12881 for john deere 1010 dozer cracked
I cracked open the bleeder on the fuel pump and found that it’s nicely full of fuel. Unfortunately, this little dozer is still having fuel system problems. With them open, cranking the engine draws fuel up and purges the air in the system. I had tried turning it over with the fuel injectors cracked after replacing the fuel filters I’m supposed to bleed the air out of the system by cracking the injectors. Unfortunately, I still was unable to get it to fire. Less resistance because of a better connection equals more electricity to the starter motor. That makes sense, when you think about it. After replacing everything, the engine turns over wonderfully – much faster than it had previously.
It was a little warmer out today, so that helped things go a little quicker – plus I knew what I was doing. Today I was able to replace the wire and reinstall everything. That sucker was iced in there bad, and with the loader arms on we had a heck of a time getting it out. A few days ago I had a friend come over (Thank you Brian!) and help me diagnose the electrical problem as a faulty wire to the starter. Hey guys, just wanted to keep you updated on the progress for the John Deere 1010 dozer.
