Hi guys,
I have a '72 LT-1 that has a TI system installed by a previous owner. It's giving me some grief and I am hoping that someone can give me some idea(s) of what to check.
Here's the scenario:
There is no spark when cranking but as I turn the key toward the start position from the run position or release it from start to run there is a spark, most of the time. We were able to confirm this tonight with a timing light as well as by placing a volt meter on the wire on the starter that is supposed to feed 12V to the ignition during cranking....0 volts.
When I originally purchased this car in '06 I would turn the key and go, no problem. But during the cold winter months (I'm in Toronto) I would start it occasionally and this is when I first noticed that I could crank it for an unusually long time only to have it fire as I released the key.
I just had the engine rebuilt and while I was at it I put in a new TI amplifier board thinking it was likely the weak link. I got it from Corvette Central and it appears to be the unit that's advertised in the Driveline...(K+B electronics or something) That certainly hasn't solved the problem as now I can't start the darn thing at all. In fact, I'm thinking it may have made it worse.
Any thoughts on what I should check?
Thanks.
