OK so it was 12 degrees over nite here. Today was the first time I tried to do a cold weather start of my 590 sl with a cummins 490t engine. It could have gone better. I installed a oil heater last summer so I plugged it in 1 1/2 hours before trying to start it up. It was about 15 f when I tried to start her. She always fires right up and purrs like a kitten. Not today. She started but ran rough. I had to give it more and more fuel before she quit. I figured I might of had some water in the line that froze. It is now above freezing and I went down to try again. I bled some fuel using the hand pump to insure that the line was clear. She is still will not run. I put some starter fluid in and she did fire up for a few seconds which seems to point to the fuel pump. I am unfamiliar with how these work. Any in site would be great. Thanks in advance
