and yes I think the coils are a Ford part with 2 wires? if so its best to do a check for spark on each coil as that's the best test so by removing one of the sparkplugs and plug it back into its coil and rest it on the metal of the engine (DO NOT hold it on place by hand) then have your assistant turn the engine over whilst you watch the plug. It should give a fat blue spark at regular intervals.
If not then check that there's power to the coil pack using a meter. If there’s 12V at the pack but no spark then check the ECU power supply(fuse and relay) and also the connections to the crankshaft speed sensor.
