looking at your above pin-out, either :

it isn't a L6
it is a L6 but someone's seriously fucked about with it
it never ran
someone nicked half your loom
you are misreading the numbers on the plastic loom plug (undo the screw and take off the cover)

As said above, all of the following are required:
pin 19 - earth
pin 28 - relay feed to ECU
pin 29 - coolant temp sensor
pin 30 - map sensor and TPS
pin 31 - air temp sensor
pin 32 - injector no.2
