1.2 16v Mk2 Starting Problem - Relay(s)
Just copied this off another site its supposed to refer to a MK2 1.2 16V Hope it helps
If the engine won't turn over, remove the small wire to the starter motor. Check you get 12 volts when you turn the key to start.
If you do, check the engine earth lead is not broken/corroded/insecure.
You have checked all the fuses - in car and under bonnet? Every one?
Under the bonnet fuse box, fuses nos. 8 and 10 which are both 60amp. They both control ignition switch, fuse box and light switch and auxilliary ignition circuits relay. Pull them out and make sure they are not corroded at all.
As you can see, these fuses control the ignition switch which runs to the starter and the light switch. Can you see the connection?
Under the bonnet in the smaller of the 2 fuse boxes are some relays. Relay 3 is the engine control relay, its the small one on its own beside the 2 large ones.
You know the fuel pump works so swap relay number 4 with number 3 (if they are the same) and listen for the pump. If it runs then you have eliminated that relay.
