What is the fuel pressure when this is happening?

60 before crank and 54 during crank.

That's a bit too low. It needs a minimum of 56-57 to start in cold weather.

You sure? It has a new gas pump. I forgot to add that to the list.

Yes, I am sure. You should be seeing over 60 with no vacuum and this engine is VERY pressure sensitive.

Okay, thanks a ton, on a side note, any tips on shutting up a ticking lifter?

Put a quart of Marvel Mystery oil in it and see if it's just sticky.
