The PT pump is robust, but it can wear out or develop issues. Key symptoms of a failing PT pump include:
Difficulty Starting or No Start: Low output pressure from the pump means not enough fuel reaches the injectors to start the engine.
Loss of Power Under Load: The engine may start and idle fine but stumble, smoke excessively (black smoke from unburned fuel), and lack power when you accelerate. This is a classic sign it can't supply adequate fuel pressure at higher demands.
Engine Stalling or Erratic Idling: Fluctuating pressure can cause the engine to run unevenly or die unexpectedly.
External Fuel Leaks: Visible leaks from the throttle shaft seals, gaskets, or drain gallery plug are common on worn pumps.
Before condemning the pump, always check for simpler issues like clogged filters, air in the fuel system, or a faulty governor.
