Crank-prime PW

I assume the prime PW is injected on the first pulse when cranking? If you bump and release the starter without it starting will it prime again when you hit the starter a second time?

Re: Crank-prime PW

EBL? The crank prime PW is only once for each power up of the ECM. If the ECM is reset (key-off or low battery on crank) then the prime PW will occur again.
