3406E won't fire up.

push the shrader valve and see if you have fuel pressure, if there's no pressure reprime the motor with the hand pump (200 pumps sometimes), it sounds as though you're not getting fuel up to the cylinders. Before priming if you have any available I'd recommend cracking both filters loose and topping them off with power service/whatever additive you have on hand. You may want to have a can of WD40 handy as well and a helper if you can find one.

I wouldn't recommend ether, and if you didn't have enough ether in the air cleaner it still won't start I fought this problem earlier this year and for 2 days straight last year. took almost half a can of Wd40 and pulling the boot on the head to get it to fire off finally.

Also when priming the motor watch for fuel around the primer pump if you get fuel on the primer pump handle you need a new primer pump and that could very well be the cause of the motor losing prime which is what it sounds as though has happened.

Are you getting any smoke from the stacks or anything of that sort? If you're getting smoke you're getting heat and at least some amount of fuel up to the injectors it just may not be enough to get the motor to fire off. I feel your pain though had my motor torn down july of 14 to the tune of 22k, before the overhaul it could be well below 0 with gelled fuel in the tanks and that motor would start might not run long but it'd start. Now if the #### temp is below 20 I've got it plugged in and my fingers crossed when I push the starter.

 

^^^^^

2nd priming the fuel system. Watch out using ether. Its like meth to engines. Don't want to get it hooked.

 

+1 on ether being meth. I carry a bottle for frozen brakes, I've had better luck with WD40 for starting fluid doesn't seem to have the crack effect of always needing it if used too much

 

yes there should be a valve under that rubber cap. push the valve in and it should squirt a little fuel if there's pressure. Don't feel bad I've got one truck with a bad primer pump that runs daily I'm just too #### lazy to fix the $15 primer pump until I service it next time.

Since you can't prime the motor you may need a helper and some sort of starting fluid if you can get the motor to fire off you can use SMALL stream to keep it running until you get enough fuel pressure to keep her running. I'd definitely recommend topping the filters off though. As I said I use WD40 and have never had an issue with them getting addicted but I could see that happening over time. just like with ether. good luck with it

 

If you got no primer I would get someone to crank the engine while you crack the return fuel line at the check valve. This will confirm if you have fuel and also bleed any air out .

 

I think the issue with ether is it washes away the lubricant on the cylinder walls and causes the liners to glaze up. WD40 works just as good and its a lubricant.

 

Lossen the fuel line on back of the head take air hose put air in the fuel tank through the vent tube pressure It up its best to use a regulator set at about 5 psi till u got steady flow of fuel at the back of the head
