Possible opti problems

[96LT1355Z28]

If you have spark at the coil it has to be the coil wire, cap, or rotor. Even if the spark was too weak to fire the engine you would still see it at the plug if the coil wire, cap, and rotor were working.

Quick update- I've got spark, but the car still will not hit. It is a weak spark, but more that what was there nonetheless. Car still doesn't sound like its trying. The arc is not a nice pretty blue, but more of an amber colored arc. Re-checked fuel pressure and I've got fuel.

Now I'm really confused, but I suppose a little spark is better than no spark at all.

How old are the plugs and wires?

[Tyler Wheat]

I have an OTVC kit that is a few years old, but not many miles. There's a new plug on the wire that I have pulled to check spark at the plug. It's a really weak amber spark. The problem was not progressive, however. The car was running great and then just crapped out all of the sudden.

Spark seems to be consistent and on-cue, but it is really weak. New coil, opti, and ICM, too. Otherwise, I would think the coil was the culprit. I've tried both the old and new coil with the same weak spark as a result.

Try another coil. I've personally seen a car that had enough spark to light a timing light but not fire the car. A new coil and it fired right up. He had an orange spark not white/ blue at the plug.

I have a new coil and have tried both coils with the same result. I may go ahead and return it and order an MSD one for the price. I just took what O'reilly's had on hand to try to get the car up and on the road when I bought it.

Do you have a bright blue spark at the coil but not at the plug? As someone suggested earlier I would try a new coil wire.

[Tyler Wheat]

I have good spark at the end of the coil wire. I think I have it figured out, though. I went through and slightly (and carefully) bent down the rotor and now its hitting on a couple of cylinders, but still won't start. I think I bought a bad opti. I'll send it back and let you guys know when I get the other one if that fixes it. Really weird situation. When someone said that a friend got one that was 180 degrees off, I started to ponder. I've always had really good luck with the Delco unit on my cars and my friends'. Just my luck as of late, I guess.

BTW, is there a good way to tell if you are making contact on the cap and rotor? I couldn't confirm if I was making a good connection or not.

Thanks for everyone's input. Hopefully I'll get the new opti and that will be the end of this thread.

Just an update in case anyone else comes upon this thread with the same problems. I replaced the opti with a new one today and she is running good as new. Problem solved and I'm pretty darn happy that its running again.

Only problem is that the opti connector was broke during shipping. That's my luck going against me again haha. I'm going to get yet another one that hopefully isn't damaged during shipping this time! It was a good enough connection that I could verify that's what my problem was, but no way am I driving without the opti harness being secure. These things are tempermental enough as is!
