I have fuel, but no spark

[milkmania]

91 PS190 351 Indmar/with Holley carb.

I found out today, that I do have good fuel flow, but no spark.
I pulled a plug, put the wire back on the plug, then grounded the metal part of the plug, cranked it over and no spark.

In saying this, I also do not have reading on fuel gauge, amp gauge, or depth sounder.
blower/bilge/horn/lights/acc all work fine.
tried resetting push button switches on control panel, and the red switch on the back of motor. confirmed lanyard/kill switch was secure.

I need an idea on where to start, and what to bypass for troubleshooting purposes only.

thanks guys
