I am an experienced road course/HPDE driver and instructor. My previous track car was a 2011 BMW 135i, pushing about 400HP/ft-lbs, used for about 8 years.
Well into my 4th track day with the 2022 Mach1/HP with 12,500Kms/7700 Miles on the odometer, the car stuttered and eventually died. OBD code reader revealed low fuel pressure. Needless to say, I needed to get towed off the track (red flag), and then towed home as this happened on a late Friday afternoon, after dealership business hours. I did not want to let the car sitting outside of dealership, unattended for a whole week-end.
The car had a half tank of fuel when this happened. Ambient temperature was relatively hot, around 29*C ( 85*F).
All fuses and relayed checked out good. OBD codes generated were P00C6, P0087, P008A (Fuel Rail pressure too low/ Low pressure Fuel system, etc).
The Monday after, I used Ford Road Side assistance to get the M1HP towed from home to dealership, where a bad fuel pump was the root cause. Part should arrive within 2-3 biz days.
My verdict is that perhaps the fuel pump lacked cooling due to G forces/starvation, as I was driving the car hard on 100TW sticky tires and Hawk DTC70 race pads.
The 61 liters ( 16 gallons) tank is ridiculously small for this "track-ready" car. I will now carry two Jerry cans to my track days, and never let the tank go below half-way mark.
Any of you track guys experience something like this in the GT's, Bullit's, or Mach1's?
