The relay may only be for power to the fuel pump control unit. Newer vehicles are Pulse With Modulation (PWM), fuel pump directly powers it. Maybe try the crankshaft position sensor if it’s more accesible? I’m not sure if either out would set a CEL once it was back running though.
All I was saying it’s that it’s not in the states. It looks like they only have 3 options in MX ford website. Not sure how their pricing works on the models. Usually Ford reserves special trims at a higher price point in other countries
This appears to be in Mexico, wonder if the trims are not all available there? Not sure, but yeah, would think fenders + flares and paint would’ve been a better route than a HE
Did you install an ethanol content reader or just going off a tune/mix ratio. Locally in my area E85 is hard to find close to it usually it’s only 50~78% max.
