M813 Primer pump

[cbvet]

Tried to start "new" M813A1 at 30 degrees. Followed instructions on dash. Turned on glow plug & attempted to pump fuel with the hand pump. Pump goes in about half way, then stops solid. Gauge is stuck, so I don't know if there is any pressure build up.
Cranking good, but no start.
Had to use a quick shot of ether to start.
I know I need to check the glow plug & wiring. May need a new gauge. But what about the pump?
Are there seals in it that go bad?
What should I be looking for?

Thanks in advance,
Eric

It's o-rings inside there. Was the ign. sw. on?

Ignition has to be on to crank engine, as the start is built into it. Battery switch was on.
I'm sure I can check the electrical components, just wondering about the pump.
Standard size neoprene O rings?

Change tactics. Mine was a royal PITA even when working in sub 30 degrees.
This is what I did: http://www.steelsoldiers.com/index.php?name=PNphpBB2&file=viewtopic&t=10189&highlight=

Works like a champ if you do not mind the whole "not OEM equipment" view.

Check that the fuel priming pump works, you can hang a bucket from a fitting and open the high point valve in the system. Are you sure your fuel hasn't gelled?

Fresh fuel, & it runs great once it's started.
If I don't have to work, I'll look it over good tomorrow.
Thanks to all for the advice!
