The diagram is for ignition module, 1.9L engine. How long since a tune-up? Any applicable trouble codes? Did you check voltage and ground at the ignition module? In the diagram, top left, pink wire is voltage, fuse protected and goes hot with key on. The bottom left, black wire, not seen in diagram is ground. If you take wire connector loose, use both ends of test light touching the terminals for those two wire colors, key on, if the lite comes on, you have voltage and ground good enough for the lamp. If no lite, then your missing either voltage or ground, or both. Now, if no spark--no fuel pump activity and no fuel injector pulse, check for rpm signal comes from crank sensor. Don't replace anything unless your testing points in that direction. Just my opinion.
