Did you do a compression test on those two cylinders ? Check spark with spark tester ? of course the advance is going to jump around with a missing engine . Timing issue ,jumped time , engine mechnical problem . Testing an not guessing .
When key is turned the starter is energized by a solenoid that applies power directly from the battery to the starter. Any loose connection will prevent the starter from turning over. The solenoid can also have burnt spots on the contacts inside case that will prevent current from getting to the starter. A click noise is the solenoid energizing so
if all connections are tight and the battery is good the only
other problem is the starter may be bad. Brushes on the
starter may have seen their life ended. this is usually identified by tapping on starter with a hammer while trying to start engine. If starter spins, replacement is needed.
Unless it was a sound of your valves beating the top of the motor that is one of the most normal sounds for any operational engine is the click the clicking you hear it's going to be electricity going through your coils so it's pretty normal if you have a distributor base system that would be different I'm pretty sure your car is a OBD2 so it would be a coil base system so I wouldn't worry about it
A/C compressor clutch relay maybe . It's located in the under hood fuse box . If you look on the bottom of the relay an see pin's 30 & 87 an locate where they plug into the fuse box an jump with a piece of wire . Just to see if clutch engages . Pin 30 should have B+ voltage .
What does scan data show ? Do you know what that is ? What do the fuel trims show , is the computer adding or taking away fuel ? Are the O2 sensors switching normally ? EGR valve stuck open .
