Secret sauce?
Hey guys, I am a vacuum of desperation. Sal C. has been mentoring me so graciously, but my stupidity has reached i=ts limit me thinks. 1986 Porsche 911 3.2 M491. Car has undergone extensive renovation. Now a no start issue. No problem. Found bad Speed sensor. Replaced. Still no start. Checked methodically with Sal C's help and guidance. No power to pin 30 on DME relay. Ah... Power checked red wire from socket pin at DME to firewall. Excellent voltage. Reversed and checked from battery to last access point at fuel filler inlet at tank. All good. Somewhere in (DME harness Relay) in a 16 inch section of harness (4 wire total, 12v constant from Batt, Fuel pump, coil x 2) 12v constant from battery is not conducting power... seems to be broken wire. Failure occurred while car parked and not driven for a few weeks. Hmmm. This harness is inaccessible to my efforts from cabin firewall floorboard penetration to aforementioned point outboard of fuel filler nozzle at tank. Schematic shows this part of DME relay harness joins an addition 4 group of conduit into a single conduit for the 16" run downward and thru the frunk floor and into cabin firewall. So who has the shortcut, secret sauce, at gaining access to this harness, and how in the world could it be severed, burned, cut, etc... Rodent free environment. No fire damage. Really immaculate low 60K mile car, totally rebuilt except trans, new everything. Struggling here for a method?? HELP??
Thanks!
