Wangan280 Posted March 5, 2013 Share Posted March 5, 2013 Hey guys! I have an 86 Z31 N/A Coupe...a few problems have come up and I'm not sure what to do. -very rough cold start. I'm suspecting it's the CHTS, so I purchased a new one along with a new subharness. I would have to crank it 8 or 9 times before it would catch. It doesn't have a problem starting warm. -There's a new problem where I'll have to unhook the battery for the car to know there's enough charge to start up. other wise I'll turn the key and the start lights will come on but the starter won't click or anything. If I unhook the battery and hook it up again, it goes back to normal. I have no idea what it is. The battery terminals are new, and it will fire up once I unhook and rehook it. If I turn it off and back on, it will work fine. If I come out the next morning however, it will just be like it's dead. Unhook and rehook the battery, and it will crank 8 or 9 times then start. HELP? So annoying... Quote Link to comment Share on other sites More sharing options...

Wangan280 Posted March 6, 2013 Author Share Posted March 6, 2013 all of the lights that turn on when you put the key into the start position (gas,wipers,warning etc) Quote Link to comment Share on other sites More sharing options...
Domzs Posted March 6, 2013 Share Posted March 6, 2013 You might have security problem that prevents starter from cranking . Check starter signal at the starter to see if it gets 12v. during crank . Quote Link to comment Share on other sites More sharing options...
