Century 3035 won't start

[Zork]

Great progress. On many injection pumps (IP's) with "external fuel cut off solenoids you can hear a distinct click or knock when you first turn the key on; does yours have an external solenoid and does it make that click when you turn the key on? If not there and since you powered it directly I suggest you have something going on in the circuit.

Since your voltages are "bouncing around" I would make sure your meter battery is good and then check all of your connections, including battery; especially ground.

You can cycle your ignition switch several times to see if that clears it up and I'm not sure if there is a relay that controls the fuel cut off solenoid.

Once your run your engine out of fuel it typically wont start like a gas engine; it will run at an idle and die and run a little better and better each time after you've restored your fuel supply and removed the air.

Zork - According to a cross reference document I found your 3520 and my 3035 are identical.

I also verified that the Stop Solenoid was keeping the tractor from starting. I held the solenoid back and had my son start the tractor, everything worked fine. Just need to track down whatever is causing the solenoid to not engage.

Zork, thanks for your help.

Great! and congratulations on your repair. I do have a manual for mine so if I can help in this just pm me. I have not checked my capacity levels yet; the last week and this coming two weeks are going to be a bear for me.

Got it all back together and working. The Stop Solenoid was not working because the fuse connector was dirty/corroded. Cleaned the fuse block connectors and put a new fuse in and it started working.

Thanks gain for your help Zork.
