I have performed a top-end rebuild with a rebuilt IP, new lift pump and new injectors.
Timing set per factory specs with proper tools, valves adjusted correctly.
When rotating engine by hand and fuel solenoid energized, the IP pulses fuel to the top of #1 cylinder just after the exhaust valve closes and the piston is 10-15 degrees after top dead center on the intake stroke. This can't be right.
Further cranking verified the timing order of the IP is correct, however it pulses, from what I can tell, slightly less than one complete revolution of the crank out of time.
If I had the crank at TDC, flywheel pin engaged, cam gear mark dead on the casting mark and IP timing pin engaged when timing belt was installed, the only solution I can imagine is that the IP flange (to which the IP gear attaches) was mounted "upside down", or nearly 180 degrees out.
When the IP pulses, the timing pin slot for the IP is at 6:00 on the pump, not 12:00 as it should be.
Thanks in advance for you help.
