      Have 2006 Yukon XL with 6.0L

      Truck started in driveway and then died after 10 seconds (over a week ago.) No codes stored other than a bad O2 sensor that has been there a month (I have the part now), checked fuel pressure, running 55-62 PSI on cranking have fuel injector pulses on cranking. Swapped out Crank and cam sensors, no help. Ran an extra ground to the firewall from each head after suggestion from co-worker….

      Coil plugs have 4 wires with clip at the top, left has power, two to the right have continuity with ground.

      Any suggestions?
