2000 Venture Full Power, but won't START

I have not had any problems with my 2000 Venture WB edition. Then today I leave to go to the store in the snow, leave store starts fine. Get home and about a 2 hours later, it won't even try to turn over. Lights, radio, and even the TV works, but it won't try to turn over. What could possible be the problem?

Does it just click? If so maybe starter

Could be the anti-theft system. If you turn the key on, without trying to start it, does the security light start to flash after a few seconds? If it is flashing, it is the anti-theft system. It may start again after waiting for 10 minutes.

It didn't even click, but I got in there and pulled the starter out to replace... only to find my starter was full of oil. Then find out that I had to replace a bad oil fitting unit where the oil was leaking from. Every thing runs now... knocking on wood!

Thanks for all your help and ideas.
