[QUOTE="DOWNS, post: 438718, member: 21038"] Holy crap man you replaced the whole engine because it shook? How much troubleshooting was done prior to the engine replacement? What fuel pressure are you getting? A pinched return line can cause your pressures to spike to 80-90 PSI which basically floods the engine. Too low can cause similar feeling issues. Doesn't matter if the pump is new get a fuel pressure reading. Normal Fuel pressure is around 30 psi with the vacuum line connected to the pressure regulator. 40ish if you unhook that line. [/QUOTE]
