what cause a2004 f150 to cut out and dont start

If your Ford F150 is shutting down while driving, it's a real safety hazard.  Vehicles are a lot harder to command without ability brakes or steering.

Ford F150 Shuts Down When Driving: Pinnacle Causes

Directly below is a list of the most common reasons why your F150 would randomly die while driving.  It may help you in your diagnosis.  But, before taking a look at anything, is the cheque engine light on?  If it is, you lot'll want to start with whatsoever trouble code y'all go from an OBD2 scanner.

Parts stores can scan it for you if yous don't accept access to a scanner.  But we don't recommend driving anywhere until your F150 is fixed, since dying at the wrong time can cause a collision.

1. Out of Fuel

Your engine needs three things to run properly; air, fuel, and spark.  If your engine is running fine and then it only suddenly dies, 1 of these three things was abruptly taken away.  Information technology'southward usually fuel.

The virtually common reason that a vehicle shuts off when driving is a lack of fuel.  The near probable cause is an empty fuel tank aided by a fuel gauge that's not every bit authentic as information technology looks.  Even if information technology says at that place is fuel in there, blindside on the tank.  If it makes a hollow sound, information technology's probably empty.

2. Fuel Pump or Filter

Another mutual reason that your F150 may be starving for fuel is a bad fuel pump.  The fuel pump is responsible for sending highly pressurized fuel to the fuel rails.  The engine can die if the fuel pressure is non loftier enough to properly atomize the gasoline properly.

The fuel pump is frequently not monitored by the engine's computer, which means information technology doesn't activate the check engine lite when you are trying to figure out why the vehicle it is randomly dying.  This is the best identify to showtime.

If the engine isn't starting, turn the key to the on position and mind actually carefully.  You should hear a whining noise.  That'due south the fuel pump priming the fuel organisation.  If you hear nothing, that is a stiff indication that the fuel pump is bad.  Since the fuel pump is in the tank, you lot may desire to get a second gear up of ears so y'all tin can be absolutely sure y'all don't hear it.

If you don't hear it at all, you should manually check the fuel force per unit area at the fuel track.  If it is not every bit loftier as it should exist you either have a bad fuel pump or fuel filter.

The fuel pump may be going out sporadically.  This would mean that it'll dice on the road, and then fire support again even a few seconds later on.

3. Battery Cables

Check the battery cables to ensure that they are free of droppings and are bolted to the bombardment posts properly.  Follow the black basis cable to whatever it is connected to.  Make sure that it is secure and there'south no corrosion or rust that could be keeping it from making a solid ground connection.

4. Engine to Chassis Ground

The engine needs a strong ground to the chassis in guild for your F150's various electric systems to work.  If that cable is corroded, there could be problems such as misfiring, slow/no starts, or even the engine dying while driving.  This is a common crusade of many "gremlins".

5. Bad Alternator

The alternator is responsible for charging the battery, and keeping your F150 running.  If the alternator goes bad, the vehicle volition run off of the power supply in the bombardment (which is there more often than not for starting the vehicle and as a backup reserve).

Once the battery has been depleted, the ignition system will no longer exist able to fire properly. You should see either a battery light or alternator calorie-free long before the engine dies.  If you didn't see it, it'due south highly unlikely that the alternator or battery is at mistake.  If you did come across the alarm calorie-free, have the alternator and battery tested at the parts store.  Replace them as needed.

6. Outcome With Sensors

The crankshaft and camshaft sensors are responsible for telling the engine where the creepo and cam are located in their 360° revolutions.  If they stop reporting this data, even momentarily, the vehicle will non know when to fire the spark plugs and it'll cease running.

The mass air flow sensor tin can also go bad.  These sensors should trigger a trouble code if they have a trouble through.

Conclusion:  Ford F150 Dying While Driving

In the absenteeism of a check engine lite, take a good difficult look at the fuel pump.  If that'due south non the upshot, nosotros recommend having an experienced mechanic take a look at the problem.  They'll demand to tape the telemetry from the OBD2 system when the motorcar does it once again.  And so, they'll be able to determine which part of the vehicle has the problem.  This is a DIY site, nosotros hardly ever throw out the mechanic recommendation.  This can be tough to track
