I was able to visit with my A3 at Warner Robbins this week and got 2 new tires put on it so it is ready to roll. Unfortunately it won't start. The fuel tank was EMPTY and I think it may have also been run out of fuel. I put in 10 gals of diesel and cranked, intermittently, for quite a while. I got fuel to the filter for sure. I was able to run it for about 20 seconds, carefully, on starting fluid but it wouldn't stay running. A local Cat dealer said these are very difficult to get started when run out of fuel and said they put suction on the return line to help. When we go to pick it up, with a trailer, next week I'll start with a new fuel filter and go from there. The engine looks "new" and the truck has 3800 miles and 125 hrs...Any wisdom from the board greatly appreciated.
