Have you checked your starter motor? That was what killed my ZR in the end. It became so rusted and corroded that it just fell apart basically. When I tried replacing it myself the nuts were fused and some of the wiring basically fell apart in my hands. Had to scrap her after. I hope your issue doesn't end the same way but it's definitely worth looking at.
