Cranks great, won't start. Fresh gas, all lights, horn, etc work fine. All fuses look fine; even replaced the ECM and fuel pump fuses anyway. Problem? The check engine light and "hissing" sound of fuel pressurizing is missing when I turn on Run switch. I ran all diagnostic codes in my 986 page service manual. Responses were: "none", "no reponse", and "part number...", but no problem codes. Now manual says "probe ECM Terminal 13 etc" which is way over my head. Anybody see anything I can do before calling the tow truck and shipping it off to the dealer? :hii
