First clean with alcohol on a qtip.
If that doesnt work, pry down the pin on the topper just a TEENY tiny bit.

If you are still getting a non reading after each of the above - CAREFULLY pry up the firing pin in the well on the MVP2 - just a TEENSY LITTLE BIT.

If all of the above fails - maybe a new coil? Or just give up on that topper
Hope this helps!
