if its still not sparking, and your getting a reading from 1 end to the other of the cps wire, then the problem is got to be ecu or fuse/relay.
take the ecu plug off and have a look for any bad pins.

oh, 1 question why i think about it, you havent got the injector loom plug and car-ecu loom plug round the wrong way have you? there the same size and shape and ive known someone do it before
