What you should have done in the first place, before replacing random things and possibly introducing a second or more faults.
Check (with a 12 volt bulb, NOT a meter) that ignition switched power is reaching the coil packs and the ECU, and that the permanent 12 volt supplies are present at the ECU and relays.

Fuel pump needed replacing then I had no power to the pump did a relay bypass and I only get power with the key on the off position. I have power to the coils just no spark so I then replaced the crank sensor but I'm not getting any spark

Confused :mad:

So you bypassed fuell pump relay and now it only works with the key in off position? This might be your problem then cause i don't even know how is it possible :roll:
