Quit running, blew ECU1 fuse (30amp)
Darn fuses are 4 bucks!
Driving around normally, then just quit.
Engine cranked, fuel pressure at rail. No spark
Bottom line; O2 wiring that runs down left side of valve cover was melted and shorted on exhaust manifold. Repaired wires, replaced fuse, engine starts and runs fine...
