My 2005 ford taurus will have trouble starting. Going down the road a digital read out will light up my dash saying CHECK BRAKE SYSTEM and car will power down. All times except for today it powers back up on its own, today however I had to pull over and re start myself. Ive heard dirty filters bad fuel pump etc. Also have clicking noises when car is off when I try to start no power I pump my break clicking stops and Im able to start the car. Ford wants to charge me 110 for a full diagnostic but cant promise that if its not acting up at the time of testing it will reveal anything. Any help would greatly be appreciated.
