Start with the cold start system. A bad or plugged up cold start valve could cause these symptoms. Make sure there are no vacuum leaks as when the engine is cold they are even more noticable. Also check ignition timming and advance. Open the distributer and make sure the mechanical advance isn't stuck. You could also check fuel pump pressure and delivery as if it isn't up to specs you won't have the cold start valve working right. Try turning the ignition on and off a couple of times before you start it cold. If that helps the problem is fuel delivery. On many Deloreans as with most older cars after you fix one problem you uncover underlying problems. It can take a while to finally get all the gremlins out. The overheating problem could be anything from air still needing to be bleed out to a bad fan fail relay, to the origional circuit breakers to a bad otterstadt switch. Rule out all of the mechanical problems like a fan motor bad or running backwards, pressure test the sytem to rule out leaks and then go over the electrical part of it. Little by little if you keep at it you can make the car reliable.
