Default Re: Fiesta WP 2004 won’t start

Two possibilities with that symptom - either the Battery has gone open circuit/short circuit on one of the cells, or the alternator has failed. Do the battery test first. Or if the battery is over 3 years old, just get another one.

The immobiliser on the Fiesta is quite similar to that of the BA Falcon - they even use the same type of key. The key itself doesn't need a battery - it is 'excited' via radio from a ring around the ignition barrel. If you suspect it to be your immobiliser, try your other key in case it is a problem with the key.

But all of this is vulnerable to battery health. Take that step first.
