Ford Focus and Fiesta 2004 - Ignition Coil Failure Problem: Engine misfire or no spark During diagnosis a faulty ignition coil is identified as the cause of the misfire. It is common to experience a continuing misfire even after replacing the ignition coil. If this is the case then it is very likely that the ignition coil drivers located inside the ECU have been damaged by the faulty ignition coil. Diagnosis: ECU has possibly sustained consequential damage because of the faulty ignition coil. The ECU is then sent to AFI – Australian Fuel Injection to be checked, tested and repaired as required.
Important Note Even after the ECU has been repaired it is very important to ensure the replacement coil hasn’t been damaged by the faulty ECU sustained from the original coil failure. Remember, the coil was replaced in the first instance and connected to a damaged ECU that exposed the new coil to excessive electrical current. Failure to do this will again cause damage to the recently repaired ECU Remedy: 1. Determine whether ECU has been damaged by thoroughly testing the ignition primary circuit prior to replacing the faulty ignition coil in the first instance. 2. If the ECU is diagnosed as faulty, call the AFI team to arrange to pick-up the ECU [or send it into your nearest AFI branch] to be checked, tested and or repaired. 3. If the coil has been replaced in the first instance of diagnosis and was connected to a damaged ECU. Then, it’s best to replace the ignition coil again after the ECU is repaired. 4. Ideally, it is best to have the ECU Tested before a replacement coil is installed in any case.
