4) If fuel pressure drops below this level, check as follows:

a) Completely pinch off flexible hose of high pressure fuel line (to engine) and flexible hose of low-pressure fuel line (return).

b) If pressure drops, check for the injector or cold start injector leak.

c) If pressure does not drop when the lines are blocked, pinch off only high-pressure hose, leaving low-pressure open.

d) If pressure drops, replace the pressure regulator.

e) If pressure does not drop after either step (a) or (c) replaced the fuel pump.

Das werde ich mal so testen.
