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
