Put the engine on TDC and make sure the rotor arm is pointing towards number one cylinder. There is also a groove in the distributor to line this up.
This is assuming you are still running the standard system.
Then check the connectors for the dissy and crank sensor have good connection and are the wright way round as i have seen these forced together the wrong way round before.
I would then check you have the right gap on the phase sensor and that the crank sensor is mounted correctly.
