[QUOTE="Tiha, post: 1563476, member: 33189"] Well low pressure is 62 psi per maual gage. Still won't start. Rail psi not coming up. Pulled intake again. Pulled flow control valve. Still clean. Pump full of fuel. Found this. "quick tip here. The typical failure with cp4 pump is a bad valve seat on the Intake non-return valve (suction valves). We have found that when an injector line is cracked open, and the key turned on to operate the lift pump a good cp4 the fuel will ooze out. In the case of failed suction valves the fuel will poor out and travels about 1.5 to 2 inches up." I tried it and my fuel definitely shoots into the air a few inches. According to that my cp4 went bad. Sitting in my garage. Nice. Can anyone confirm? I am not even sure what to check next. I unplugged the pressure sensor so it showed 30k rail pressure. Still no start. [/QUOTE]
