its behind a small plastic cover, almost bang on in the middle of the car between the footwells. Its probably easier to just listen for the fuel pump when you switch ignition on to check it.
From your first post I feel like you are looking at the 1108cc info in the manual and have a 899cc engine - the coils on an 899 are one above each other unlike the 1108 engine.. From memory, and its been a long time since i touched a 899 but, the lower coil is 1&4 and the upper 2&3.
As with the other thread I just replied to, make sure the bottom pulley (the ones that bolts onto the crank and has the alternator belt on) is the right way round, it has to go the right way or it won't inject fuel or spark the plugs at the right time.
After that you wanna check you have both fuel and spark. Take the bob off the top of the throttle body and look down at the butterfly while someone cranks it over - you should be able to see fuel pooling a bit on the butterfly - not much but you should see it.
For spark take one of the plugs out out and just lay it on the valve cover with the HT lead attached and crank the engine and check its sparking. If you like you can test one from each coilpack to be sure they are both firing.
If you have no spark or fuel then its 99.999999% going to be the crank sensor needs changing, or its not properly connected or its wiring is damaged.
