If the fuel pump relay wasn't hooked up correctly and not working, would this be the reason why the coil wouldn't be firing. What is the output from the coil transistor wire coming from the ECU?

Nope.

EC U OP for coils should be square wave 0v rising to +5v for approx 3.5 miliseconds then falling to 0v.

What would be stopping my car from producing spark?
Could it be a sensor or ECU?

I hope it is the ECU because i have another one on the way. I have checked the wiring and cant find any problems and all i can put it down to is the ECU. Could this be causing my spark issues?

Sorry M8 but it could be a range of issues from simple to complicated.
Cannot say unless actually have the car in front of me.
Good luck.
