Ford Explorer engine will not start with less than a quarter tank of gas when parked on a slant on Ford Explorer

Some Ford Explorer owners report experiencing starting issues when the fuel level is below a quarter tank, especially when parked on a slant, which can lead to fuel starvation and prevent the engine from starting. Additionally, some owners have identified a problematic fuel pump as a contributing factor, as it may fail to deliver fuel effectively to the engine. Ignition system problems, such as faulty connectors or issues with the ignition switch, have also been noted as potential causes of starting difficulties. While not directly related to fuel levels, some owners find that a weak battery can hinder the engine's ability to start due to insufficient power. Furthermore, issues with the starter, including a faulty starter motor, can prevent the engine from cranking properly. It is important for owners experiencing these issues to consider all these factors for prompt resolution.
