"HAVING YOUR FICM CHECKED" IS NOT ALWAYS THE SAME AS YOU CHECKING IT CORRECTLY. YOU NEED A MONITOR. LOAD TEST YOUR BATTERIES AND PERFORM THE FICM CHECK PROCEDURE WHEN IT IS COLD. IT ALSO SOUNDS LIKE YOU MAY HAVE THE START OF A HPO LEAK. WITHOUT A MONITOR ALL THIS IS GUESSING.

BTW, it is not necessary to type in all caps........

Sent from my phone that somebody didn't help me get.

Yea, I was just jerkin your chain. Warm hard start is usually the start of stc, dummy plugs, and standpipes leaking, any or all three.
You need a monitor, you should be able to see all that.
