I'm stumped any help would be great cause I am out of ideas

If the box works on your friends car, then does his box work on yours? Are you swapping out just the box or the whole harness too?
Not sure if this is it but back in the early days it wasn't uncommon to find a box that was incompatible with specific cranks, usually aftermarket cranks. With no crank signal the thing isn't going to fire.
Give MSD a call and have them see if they can come up with a meaningful test. They might end up having you send the box in. Sometimes they can fix it with a reflash.

thanks for all the replys
yep put all new sensors in and tried the ones off a mates car only thing I can think off if even possible is im using a hi torque LHS starter motor is it possible it could be dropping the voltage when im trying to start it? I have a relay on it as well the motor is standard with a cam and was running when pulled out of another car???
