my 850 turbo station wagon had a bad electrical meltdown that appears to have started at the constant fuel pressure relay (which was replaced two months ago with a new one) Also replaced starter and fuel pump(used, but working) two months ago. Fixed the meltdown of wires got new relay, seemed fine then had another meltdown on first test drive. Melted down about 20 minutes after driving. Afraid to fix again...running out of resources for wiring harnesses and need to figure what is causing meltdown
