No Start after new fuel pumps/filter install. 08 230 / 343 excalibur

Like it says, just replaced both the high and low pressure fuel pumps. New filter and gaskets. Cycled the pump several times to fill the FCC. Good cranking, but no fire. Good pressure at the fuel rail. Any ideas? Kill switch is fine, and no obvious breakers tripped.
Sucks, was hoping to Ride Christmas day

Why did you replace both pumps? Was the boat not starting before you replaced all of this?

Yes. Checked fuel rail pressure and had a 5-10psi drop from a 56 initial pressure at key on (priming).
Low pressure pump looked like it may have been original.. 960 hrs. Decided since I was replacing it that I'd do High as well, with new filter...

Bummer. I changed both of mine a year or two ago and don't remember any problems other than it took longer to prime than I thought it would. So I just left it in run position for a minute or so.

Did you pull and ground a spark plug to verify spark?

So after some logic, It was thought that I must have a bad cap/rotor. Even though they were replaced just 60 hrs ago (March this year) and looked fine, I put a new cap and rotor and bingo... Fired right up...
