Cranks, but won't start
03 Sprinter about 55k
Last week no start dealer diagnosed a bad battery and fuel filter as the problem. I replaced battery and fuel filter and since the truck has started but needed more cranking than normal to start. It started like that all week hot or cold, and ran fine. But this morning was the first start since Friday and it cranks fine but won't start. Seems to have fuel to rail but no start.
Any help would be greatly appreciated.
