2008 Ford Focus SE has intermittent starting issues. In July, we purchased a 2008 Ford Focus SE from a private party for our 17-yr old son. Within a week of purchase, the car didn't start. After about 45 minutes the car started. When the car doesn't start, the lights on the dash will come on, the radio works, etc.
1. Battery Capacity Diminished. Far and away the number one reason that your Focus won’t start in the cold is the battery. A battery has two different ratings, cranking amps and cold cranking amps. Cold cranking amps are the batteries ability to start turn the engine over when it is cold. Battery capacity diminishes with time and use.
Disconnect the negative battery terminal. Remove the steering columns, top and bottom cover and the drivers knee panel under the dash. Unplug the starter switch on the left side of the column. Remove the security ring from around the key tumbler by unsnapping it from the housing. Electrical is done. Inertia switches used to cause frequent problems in Fords in the 80's, but I have not personally had a problem with any inertia switch. I'm sure most of the problems were misdiagnosis, or ways for unscrupulous shops to make money replacing an expensive part that most owner's couldn't find. 16. Name: Jeffrey. Ford Model: Focus. Ford Year: 2005. UK/Ireland Location: Dorset. Posted November 5, 2022. I've had this problem for a few years After putting petrol in the car or just out of the blue the car won't start.
