Default RPM drop on B Ignition

We haven't 'driven' our 12 for about a month so when George went out to fly, he got an drop in rpm's when he did the runup on "B" ignition. ALSO, on our Dynon D180, we show no oil pressure on the main screen but we do have an indicated oil pressure on one of the other screens. And since things seem to run in threes...when we had the top of the engine cowl off, we noticed gas dripping from the mechanical fuel pump...
When it rains it pours...
How do we go about checking the ignition modules, how do we check the mixed oil pressure readings, and do I need to replace the fuel pump if I was able to stop the drip by crimping the top half to the bottom half of the fuel pump? (we'll probably replace it anyway.)

If the fuel pump is the original - AC - pump, you need to replace it now.

Ign. Switch the connectors at the modules, and see if the problem follows the switch.

Check the oil sender wire connectors. Re-crimp them. See if that changes the readings.
