Is there a fuse for ignition coils?
The ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle’s ignition system, and some of the fuel system’s components.
What can cause no spark and no fuel?
If there is no spark or fuel, then the first thing I would do is check the vehicle’s fuses and relays, particularly the EFI main and ignition relays. It may be possible that one of these components has failed and is cutting off power to the vehicle’s ignition and fuel systems.
Will crank sensor cause no spark?
A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. In ignition systems with a single coil and distributor, a bad coil or a cracked distributor cap or rotor can prevent the spark plugs from firing.
What causes no spark in engine?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Is there a problem with my Ford Focus?

Why is my Honda focus not cranking up?
If the battery measures anything less than 12.3 volts it is low enough to cause this issue, and the battery is the most common cause of this problem. And if it won’t pass a load test then even a higher amount will still fail to crank the car periodically. Just like the rest of America, one more that thinks 12 volts is enough to crank a car. WRONG.
What makes a Ford no crank no start?
You’ll see that the system consists of a fuse, ignition switch, starter relay, transmission range selector (neutral safety switch on for an automatic transmission) or a start inhibit switch for a manual transmission, and a ground control circuit provided by the PCM. The PCM gets involved here because of the ford passive anti-theft system (PATS).
