I just went out to go somewhere, and my Cummins started and ran fine, then died when I put it in gear and it won't start again. Lucky me it rolled back far enough it's in the road now, but that's another problem.

I'm going to take a shot at changing the fuel filter, and hope that's what the problem is. But I wondered before I start, do I need to bleed pressure off the filter canister before I open it up? I'm planning to use a turkey baster to get the old fuel out because I've heard the drain valve doesn't always close off all the way if it hasn't been opened for a while.

Thanks in advance.

PS I just went out and goosed the starter and could hear a pump running for about 30 seconds ... I hope that means the pump isn't the problem.
