Yesterday morning my guy comes in, starts it, same problem. It starts and runs for about 2 seconds and then shuts off. Does this twice and then will stay running and not do it again all day.

Still no codes. It idles better now with the new fps but still having that morning start problem.

that is usually only caused by air getting into in the system. Maybe pressurize the fuel tanks to about 10 psi and look for leaks.
