Have been having trouble with ignition coil on 2003 Ford E-150 V-6 Van.last inspection period the first coil failed,they replaced it that one failed right away they said it was defalt product and just

You spent lots on stuff you don't need because you have no spark.
Check the ignition system.

Ignition control module ? Is there B+ voltage on the red an lit green striped wire at the ignition coil ? Watch this video on how to trouble shoot . This is a ford pick up ,ignition system similar . 1996 Ford 150 No Start with ScannerDanner EricTheCarGuy

Trouble Code: P0340

Camshaft Position (CMP) Sensor Circuit

Possible Causes:

The following conditions may cause this DTC to set:


Incorrect harness routing near secondary ignition componentsIgnition coil arcing to wiring harness or ignition control (IC) module--Inspect the ignition coils for cracks, carbon tracking, or other signs of damage.Camshaft reluctor wheel damageThe sensor coming in contact with the reluctor wheelForeign material passing between the sensor and the reluctor wheelExcessive camshaft end-play

Trouble Code: P0340

Camshaft Position (CMP) Sensor Circuit

Possible Causes:


Inspect the 16-way engine harness to fuel injector harness connector, the CMP sensor connector, and the ECM connector for corrosion.With a DTC set, the engine may crank for an extended period of time at start-up.

none!
sign of bad coil pack.
power symptom = rough idle, unexplained and abnormal loud engine, and power lose.
drop of RPM during accelaration and engine ligth comes on.
abnormal stream of exhaust smoke.

follow the sparkplug wires..One end goes to the plugs..The other end goes to the coil...If you dont have sparkplug wires then you have coil-over coils..Thats where the coil sits right over the spark plug...

Ignition control module? There is a IDM , this module,trouble shoot this one instead. PCM uses IDM with the spout to verify coil signal from the TFI module. So basically you will need to inspect the TFI or replace and also check under the steering column there is the ignition switch (electrical switch), if that fails then you will get 6 volts to coil

have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!

Reliability of a car is all bases on experiences of owners with their respectible vehicles. In my opinion they are good car to drive for 50,000 miles, after that period they start giving you trouble. It is costly to repair it and the vehicle depreciation value is very high. Good luck

Are plugs and wires good? Did you check distributor? Firing order correct-timing set right? Maybe some of the new parts are faulty? Are grounds all secure and are fuses good?
