Won't start (cold)
I've only had my 93 Vette (LT1) for a month and it has been running great, absolutely no problems. This morning, I went to start it, and it turned over just fine, but wouldn't start. I tried 3 or 4 more times and the same results.
It wouldn't start. It was about 44 degrees this morn, but I wouldn't think that would be cold enough to affect anything. Anyone had this problem?
Got a cure? Hope it's something simple. Thanks

Jim, here is the link showing how to retrieve your DTCs and the code explanations. http://www.c4vettes.com/codes.htm
Maybe some member can provide codes that would indicate a faulty opti.

Jim, here is another link to the author of the Tech Tip for opti installation. He may help you determine the need for an opti replacement.

Re: Won't start (Jim Holbrook)
The first step is to determine if you have fuel pressure at the fuel rail. Remove the cap from the Schraeder valve on the left side of the fuel rail and carefully depress the valve core (use a shop towel or paper towels to absorb any fuel spray). If not much pressure, not turn the ignition key on for a few seconds; turn the key off and repeat the pressure test. If not pressure diagnose the fuel system.
If fuel is OK, clip a timing light onto #1 wire and have someond hold the light trigger (or tape it on) while you crank the engine. If no flashes diagnose the ignition system.
