My car won't start. It cranks but doesn't start. I have fuel but no spark. I checked the spark on every plug and nothing. I replaced the cap and rotor but still no spark. I did notice the oil seal leaking. How can I diagnose the distributor being bad? The rotor button looked really burnt but I still got no spark. The car had just shut off on me while I was driving and never sarted again. Can I check power to the distributor? I didn't have 2 codes under the mil. A egr inssuf flow and mas air flow. This wouldn't cause no spark though right?
