2001 ford mustang 3.8, standard. no secondary spark, power to the coil but no primary pulse.replaced crank shaft sensor, and maf sensor which showed as open on ohms test, thought problem was fixed but one week later it did the same thing, died while driving.

    if there is a way to bypass the passive anti-theft system I would like to know. when this happened last time the pcm was replaced by the mechanic, creating a non-recognition problem between the keys and the pcm. it ended up at the dealer where they put the old pcm back and reprogrammed the keys to the pcm. it started right up but five days later it died while driving and the original no start problem is back.

I have a 2001 ford mustang code P351A can you help me and tell me what it meas

That cutting out is a misfire . P0351 You have a bad coil ,wiring ,or PCM problem .
P0351 Through P0360 - Ignition Coil A through J Primary/ Secondary Circuit Malfunction Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in PCM).
  • Open or short in Ignition START/RUN circuit

Trouble code p052

You could have got a bad coil pack. Primary and secondary are the coil pack. Possibilities are plug wires and spark plugs also. not likely though.

Test coil pack

You can test the pack. Not sure what the tolerances for this particular pack are, but the Primary should read in the .3-.9 ohm range and the secondary usually usually 1.0-9.0 ohms range. If you get some resistance at all, it is likely not bad. If there is zero resistance at either primary or secondary, it is probably bad and needs replacing,

I have no spark in cylinders 2,4,6 on my 2002 Ford escape and three codes 354,355,356 Which means the same . After checkin those Three coils I found out , there is no negative Any advise?

P0354 - Ignition Coil D Primary/Secondary Circuit Malfunction.

Description of DTC:
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
- Check Engine Light On
- No spark

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM

Possible Solutions:
- If damage, repair ignition coil circuit
- Replace ignition coil
- Replace PCM or ECM

I have a 2004 Ford Taurus ses with a 3.0 liter v6(not the dohc model either). Today the check engine light came on. I took it to autozone to have the code run and they told me that it could be the primary...

Does the vehicle have coil on plug ignition or coilpack ? And it's not primary or secondary coil malfunctioning It's primary or secondary circuit . I'm assuming it has a coil pack because you say plug wires.
P0350 - Ignition Coil (Undetermined) Primary/Secondary Circuit Malfunction Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in the PCM).
  • Open or short in the Ignition START/RUN circuit.
  • Open coil driver circuit.
  • Coil driver circuit shorted to ground.
  • Damaged coil.
  • Damaged PCM.
  • Coil driver circuit shorted to VPWR.
P0351 - Ignition Coil A Primary/Secondary Circuit Malfunction See the description for DTC P0350. See the possible causes for DTC P0350.
Pull the spark plugs out an look at them , check the gap ,if too wide replace them . If the spark plug gap gets too worn ,the spark won't jump the gap. It will find the least resistance path to ground ,and it will do it inside the coil . Going from the secondary circuit back to the primary coil an to ground through the PCM - engine computer . The PCM has transistors inside that open an close the primary side to ground ,this builds up a magnetic field around the secondary inducing high voltage spark . Well this can short out the transistor inside the PCM . Most of the time that's what these type codes mean . The PCM would need to be replaced an programmed . This can also damage the catalytic converter. Your best bet , take your vehicle to a qualified repair shop.

I have no spark.. have replaced crank sensor, computer, coil pack.... cranks over fine just no fire.... also injectors are pulsing with key in on posistion

The coil is good after you check resistance from primary and secondary terminals, but it won't generate spark if there is not pulsing at the primary terminals. You can generate sparks by connecting at the primary coil to 12 volts from the battery. Connect the secondary terminal to a spark plug. Now the primary connection has to make pulses on off continuously (either positive or negative ) to generate the spark from the secondary terminal (now is at the spark plug). If you have spark here then the problem is the ignition module. It is a electronic device to perform the function as you just did to generate the spark. Good luck.

1991 Mercedes 300 e will not start fuel pump ok distributor ok coil and module are ok also but no sparks alarm was on and blinking but went away after charging the battery and locking and unlocking the car...

If there is no spark, either no electrical at the primary coil or the coil is not working.
if you already measure primary/ secondary resistance to confirm it is OK. Here is to test it - making electric pulsed signal at the primary terminals to see it spark at the secondary terminal.
You want to confirm everything works from the coil, so you can find out what causing the coil is not working. Here are what to check the coil before a replacement::
1- Disconnect the Positive cable on the battery.
2- Hook a spark plug directly to the coil wire ( the one coming to the center of distribution cap)
3- Find a long double wire so you can connect from the terminals of the primary coil to the battery.
4- Connect each wire end to the terminal of the primary coil. It doesn't matter which polarity.
5- Connect 1 wire to the chasis ground.
6- Hold the other wire and quickly swipe it over the positive terminal of the battery. Reapeat it until are sure that you get spark or not.
7- You should see or hear a spark. If this is the case your coil is good. If itis not, your coil is bad and it need a replacement. Problem is solved.
4- If the coil is good, the problem would be from the Primary of the coil back to the ignition key: No electrical signal to turn on the coil.
