the engine was really easy to start before..but its afternoon when i was trying to start engine. some heavy thing was on the fuel return pipe, and the fuel pressue gauge went to over 15psi, because return fuel coudnt go through the pipe..after this i removed the thing on pipe, and pressure went to 4psi as normal.BUT ENGINE COULDNT START. no fuel in to cylinder.

Are the plugs ok? they are probably soaking with fuel if the pressure went that high! |

perhaps a split in the regs diaphram if their was a restriction in the return? "Turbo's make torque, and torque makes fun"

Are you sure they are sparking though? Wet plugs can look dry but wont fire, stick them in the ht lead put them against a head stud or something and turn her over. Hold the plug with a pair of plyers though lol 1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

Hold the plug with a pair of plyers though lol i made mistake yesterday. today.. i find the plugs is wet. and engine can start now..AND i find the battery voltage changing also affect the fueling. The reason should be the speed of the pump. so i set my reg when battery was 12v. and when its 13.5v engine become really different to start |

battery voltage will make no difference to the pump, in terms of fuel seen at the carburettor.
9.85 @ 145mph

As said the pump shouldnt change, unless your batt was really flat! 1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.
