I finally went under the car, after some wrestling, was able to test the compress on #7.

Compression is 90 psi.

But here is interesting part:

at first few cranks, the compression is 90, then it shot up to 150, when I press the "release" button to release the air from the compression tester, the gasoline was spewing out from it. so it is flooded with gas.

dump questions: 1. could this be the SOLE cause of the starting problem? 2. what the cause of this flooding issue? (only on this cylinder).

thanks
