Repair of Delphi high pressure pump in Lviv

SYMPTOMS OF A FAULTY DENSO HPFP

Here are the most common signs indicating a possible HPFP malfunction:

• Difficulty starting the engine, especially in cold weather;
• Weak acceleration and loss of power;
• Increased fuel consumption without a visible cause;
• Black, white, or blue smoke from the exhaust pipe;
• Unstable engine operation at idle.

These signs indicate that the pump cannot generate the necessary pressure for proper fuel injection, and this can lead to more serious breakdowns if not addressed on time.
