It doesn't have a carb. It's fuel injected.

Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
