The timing light method is a good one. As is the infrared thermometer method. Every tool box should have both these tools.

Meh, I've done it plenty and not ever had an issue.
Curious about the timing light method. How does that method insure the cylinder is firing? All a timing light tells you is that there is an ignition pulse being sent down the wire. It's not actually telling you if the plug is firing. Similarly, it's not telling you if the injector is dead. Both of these are possibilities that a timing light won't show.
An IR thermometer/camera is probably best.
