July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Fuel Pump Pressure

  1. With multipressure tester installed, move adapter lever so it is straight upward and note fuel pressure. Fuel pressure should be 64-85 psi (4.5-6.0 kg/cm2 ) for non-turbo models or 71-92 psi (5.0-6.5 kg/cm2 ) for turbo models.
  2. If fuel pressure is not within specification, check wiring harness and main relay operation. If these are okay, replace fuel pump.
