I did test pump with my hand on it while trying to start car. It appears to be working.
Car has spark
Tank is full
Charging battery now - no hurry. My bug was feeling neglected since I got the FB, so if I need a break from the shop, I can drive it.
After battery is charged, I will test the other items you suggested
