I'll include a link to a video below that will show you how to repair the ignition coil in your Ford F250 or F350. hope this helps.
What is there stance specifications on an ignition coil for a ford 5.8 f250
disconect the coil and remove the 7mm bolt that holds down the coil, remove the coil then plug.
Is it the module or the coil paxk they are replacing? If it's the module replace the coil pack.....Or try the GM one and not an aftermarket....Or just a different brand of AM
THE COIL ON A 1977 CHEVY TRUCKIS IN THE DISTRIBUTOR CAP. TAKE THE PLUG WIRES AND HOLD DOWN RING OFFOF THE CAP TO EXPOSE THE COIL. WEDGEMAN
I would look first to the rotor, and then maybe at the module check the ignition module
Bad Plug or coil pack.
Next time you replace the coil, test and if necessary replace the resistor.
They are separate The ignition module is on the drivers side fender usually mounted in the middle of an aluminum box with fins on it. The coil is easy to find just follow the center wire on the distributor and you'll find it.
are under the coil that is held down by the 7mm bolt. the round black things.
it might be next to something hot. or there is to much power going to that coil. it might be next to something hot. or there is to much power going to that coil.
coil may be bad
Check your coil could be over heating or have a craack in it.
Commutator reverses direction of the coil every half turn so that the coil keeps turning in the same direction.
I have a 1979 ford ex cab half ton 4x4 with front leaf springs not coil springs is it a high boy?
May have Jumped time, could have a failing distributor cap and coil, failing spark plugs, bad O2 sensors, Bad Throttle body position sensor, the list can go on and on.
A solenoid valve is a valve controlled by an electrical coil. A spring keeps the valve closed. When power is turned on to the coil, a plunger is pulled, opening the valve.
If the ignition shuts down, however you can still crank the engine. This issue could be fuel or ignition related. Fuel Pump Relay failing. Overload Relay failing. Fuel Pump failing. Distributor Cap failing. Distributor Rotor failing. Ignition Coil failing. Ignition Wire Set failing. Reference Sensor failing.
check points could be coil or stator
Normally this is caused by some electronic part overheating and then failing. Can be the coil, or another sensor.
bad wire it may be grounding out
Most likely it is the armature (coil) failing, though in limited circumstances it could be fuel-related.
Check the ignition coil. At cold coils generally operate properly, when the coil heats a failing unit will start to break down and fail causing misfiring and poor engine operation. Second check for a failing ignition controller in the distributor.
You have a short somewhere Start at the coil and work back toward your battery You will need an ohm or multimeter
