If you want to check the injectors >pull the wiring harness off the injectors one at a time to find a cylinder >that is not firing, that won't hurt anything. You could use an inductive >timing light to make sure a plug is firing, or just pull them one at a time >and replace them with a known good plug or wire. Another easy way to check if the injectors are firing is much easier. Use a screwdriver much like a stethopscope the doctors have. Just put the tip of the screwdriver to the injector and the other end to your ear. The injector is basically a solenoid so a click click will be heard with the engine running.
