Hi all thanks for taking the time to read my question i have a 1990 mk4 escort cabriolet 1.6 efi totally standard with the exception of a cobra immobiliser fitter back in the day ive found no immobiliser box and the wires from the led lead nowhere my fuel pump is not working and the switch in the boot is fine before I drop the tank I want to check the relays I’ve removed the yellow, blue,red relays from under the steering wheel with no relay in the green I’ve read the efi has 2 yellow I do not and the mfi has a purple which I don’t have and rightly can anyone tell me if I’m missing one yellow and what the other ones are for many thanks
