The vehicle is experiencing an under-chassis manufacturing wiring harness restriction (Connector X185) that was installed too tightly from the factory, dropping the 5-volt reference power circuit down to 0 volts under load. This intermittent electrical failure completely starves the fuel pump, causing the fuel loop pressure to drop to a dangerous 43.5 PSI while driving (GM factory specification is 55–100 PSI). This electrical breakdown simultaneously chokes the fuel tank vapor loops, causing the fuel tank pressure to spike to an extreme -1100 vacuum pressure parameter. This results in severe engine hesitation, random vehicle starving of fuel, an abysmal 9.9 MPG average compared to the 13 …

While driving this cargo van, the driver stopped in traffic to make a left hand turn. In the middle of the turn, the vehicle stalled out and would not immediately start, exposing the vehicle to nearly being hit by the oncoming traffic. When the vehicle eventually restarted, and later brought to a GM dealer for repair, it was discovered that the main ground cable had completely deteriorated. In our fleet of 15 GM vehicles, this is now the SEVENTH vehicle that has needed this main ground cable replaced. This is a serious issue that needs to be addressed.
