- Coil Testing: To properly test your ignition coil you'll need a multimeter that can measure impedance. If you don't have a multimeter, there is an easier test you can perform using simple hand tools. Test your coil and, if it's bad, replace it.
- Distributor Cap: Your no-start problem probably isn't caused by your distributor cap, but occasionally, especially during wet weather, a faulty cap can keep your car from starting. Remove your distributor cap and check the inside for moisture. If there is even a drop or mist of water inside, wipe it out with a clean, dry cloth. Inspect the cap for cracks and replace it if necessary. Once its dry, though, it'll work.
- Coil Wire: The starting problem could also be due to a broken or shorting coil wire. Inspect the wire to see if there are any obvious cracks or splits, then test for continuity using a circuit tester.
Did it start? No? Ok, on to the fuel-related possibilities.
