Replace fuel injectors
Average repair cost: $554.36
Faulty fuel injectors represented 1.75% of repairs in 2014. A fuel injector problem can be hard to diagnose; the problem can slowly build until the part fails entirely, resulting in the car not running. Fuel injectors can get clogged by not using name-brand fuel or by picking up debris in the fuel tank by running the car when the tank is repeatedly near empty.
