ok we have just put a 90 turbo engine into a 94 car, we have it all in and it wont start, is it fuel no plenty of fuel, its also getting fire, the problem is the Cam/crank sensor isnt telling the injectors to fire. my ? is how do i fix this, we have the CAS from the old 7 bolt on there now because the connector works but this obviously wont work with the 6 bolt engine, and the cas from the six bolt 90 engine wont work because the connector is different and you cant splice them because the wires are all different colors. is it possible to get a Cas from a 91 will it still have the top mount connector???

any help greatly appreciated
