Right I have a bit more info

He has used the engine loom from the fiesta and spliced it in as normal made up the fuel pump loom and its all working, there is power to the centre wire on coil pack plug but no spark, apparently the pats on the fiesta is external i think so it has no interferance with the engine loom, but will the ecu be blocked because it's from a pats model?

Should he buy a non pats ecu? or can he just run it off edis instead on carbs?

Thank you
