Gen3 won't start on hills

[Kaibab]

OK, I am turning to the wisdom of your collective experience. My 2001 Monty has difficulty starting on cold mornings when I park it on a decline. This morning was about 25 degrees. It started, then stalled and refused to start again untill I towed it to a level spot in the driveway. This is the second time in 4 months that this has happened. Both times it would turn over, but not start. Both times i towed it to a flat spot and it started and ran fine. Have any of you guys had a similar problem?

No check engine light? I'm guessing the decline and towing to a flat spot is just a coincidence. I had a failing crank position sensor once that made me conjure up all kinds of crazy scenarios about what conditions caused it to act up.

My 01 had issues with starting. I had to keep light throttle until it warmed up. It turned out to be an issue in the vacuum lines. I would also recommend checking and cleaning the idle air control valve.

Nope, no check engine light. It just won't start. I tried to let it sit for an hour after multiple attempts, just in case it was flooded. I will check the air control valve.

A wild guess here, but maybe a faulty rollover sensor?

OK, things are getting closer. Now in the mornings I am smelling a little gas. So time to check for leaks.
