Our previous 1998 coach had a Cummins 325 and it started up immediately once the key was turned. Our new (to us) 2002 coach has a Cummins ISM 500 and, although it seems to start well, it takes 4 to 5 seconds before it kicks over; the engine has to turn over a few times before starting. The previous coach (i.e., smaller engine) fired up within a second. Is it normal for the ISM 500 (i.e., larger engine) to take longer to start?
