How many miles on the Sprinter? Have you tried using ether to start it when it won't start?
With 265k miles, I suspect that one or more injectors are worn out and causing a hard or no start when warm. An easy test for this is to run an injector return flow test. If you want to try to run this test yourself, let me know. I can post a procedure that you can use to test for excessive injector return flow...
Keep me posted...
