I have a 1990 toyota hiace diesel 2.4l engine.
I have noticed lately that the fuel pressure drops after the engine is shut down for a few hours. To start the engine, I have to use the fuel filter pump to increase the fuel pressure, otherwise the engine does not start.
What could be the cause of this problem and how do I solve it. The problem is becoming increasingly worse.
