Gutz-

By your beer in cans. Then simply drink enough to make money recyling; buy parts by drinking beer!

That's my most recent scheme. It's actually hard work......

I hope you figure it out. Can you get the shop manual? they usually have a very basic troubleshooting algorithm. (If you're lucky you can find one cracked out of the shrink wrap at your local shop and "peruse" that section. A rarity, but possible.)
