Diagnostics and Checks (Diesel Fuel Injection) (Power unit / Fuel supply / Ford Focus 1 1998-2004)

Inspection and verification

WARNING: Do not smoke or walk with a lit cigarette or any type of open flame while working on or near fuel related items. In such situations, there are always highly flammable mixtures that can ignite. Failure to follow these instructions may result in injury.

WARNING: This procedure is related to fuel handling. Always be prepared for splashing fuel. Failure to follow these instructions may result in injury.

CAUTION: Diesel fuel injection equipment is manufactured to very precise tolerances and very close clearances. Therefore, when working with these elements, it is especially important to observe absolute cleanliness. Always insert plugs into any open holes or lines.

NOTE: In addition to its normal function, the glow plug warning light also functions as a check engine light, which flashes continuously when the powertrain control module (PCM) registers a diagnostic code (DTC) serious malfunction. Minor DTCs are also stored in the PCM memory, but are only displayed when a system check for DTCs is performed using WDS.

NOTE: If a DTC is found after the problem is corrected, all DTCs should be cleared. If all DTCs are not cleared, this may cause problems with the overall drivability of the vehicle.

NOTE: If the fuel level in the fuel tank drops below approximately 4 liters, the result is erratic engine operation. This is a signal to the driver that the car needs refueling to prevent the fuel system from working «dry».

1. Check the customer's complaint.

2. Visually inspect for obvious signs of mechanical or electrical damage.
