Well I bought a CPS direct from ford parts, told him the engine type and year and model of car and it does appear to be the same as the old one. Also the rev counter flicks up when cranking the engine over, does this mean the CPS is working correctly? When I test with a lamp on the coil pack plug the light goes out completely (it doesnt blink) and only comes back on when I stop cranking the engine. I'm just baffled now, seems I've tried everything! Tried it with the PIP and SAW wires disconnected too, still nothing.
