A: You may have excessive dirt inside the tank...

You may have excessive dirt inside the tank that has clogged the fuel filter to the point that the dirt has gotten into the injectors, causing the misfire.

  • Remove the fuel filter and blow through it to see if it is clogged.
  • If it is, then blow backwards through it to see what is clogged in the filter.
  • Then take a fuel sample from fuel tank to see if it is contaminated with water or debris.
  • Clean out any water or debris in the tank and replace the filter.
