How to replace ignition coils - 1998 Lincoln Town Car

Hello. It seems your Chevrolet truck's ignition 'infeed' coil wire(s) are 'burnt out'; causing that coil NOT to 'fire'. Good luck and keep me informed; if you want to.

Here's a link from A.Z.on how to replace your ignition coil. Repair Guides Distributorless Ignition System Ignition Coil AutoZone com Here's another to a new ignition coil from A.Z. http://www.autozone.com/ignition-tune-up-and-routine-maintenance/ignition-coil/duralast-ignition-coil/chevrolet/aveo/2005/4-cylinders-6-1-6l-mfi-dohc/857013_0_17367

Step one: buy new ignition coil
Step two: find bad ignition coil
Step three: replace the coil.

Seriously it is this easy, once you buy the new part you know what to look for in your engine bay. disconnect the old one and reconnect the new one in the same way.

Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

I recommend a diagnostic scan to confirm my diagnosis of a malfunctioning coil(s).

How to Test and Replace Ignition Coil on BMW 3 Series

The following procedures apply for BMW 3 series (6-cylinders engine) 1992 - 1998 model years. To Test and Replace the Ignition Coil, do the following:

1. Remove plastic engine covers from top of engine by prying off nut covers and removing cover mounting nuts.
2. Disconnect harness connector from coil. Connect multimeter between terminal 15 (+) in connector and ground. (use a digital multimeter for the following test). See Fig.1. below BMW 3 series coil harness
3. Turn ignition on and check for battery voltage. If battery voltage is not present, check wire between terminal 15 and ignition switch. The wiring to terminal 15 (+) of the coil (via the ignition switch) is not fuse protected. Use care when testing this circuit.
4. Turn ignition off.
5. Use a multimeter to test coil primary resistance at coil terminals. (primary coil terminals: 1 (-) and 15 (+), primary coil resistance: 0.4-0 .8 ohms; secondary coil terminal and resistance: NA).
6. Remove coil and inspect coil housing for hairline cracks or leaking casting material . A leaky ignition coil may indicate a faulty engine control module (ECM). Check ECM before installing a new coil.
7. When replacing ignition coils, ensure that the replacement coil(s) are from the same manufacturer containing the same part code numbers. If individual coils with the correct specifications are not available, all coils should be replaced.

This is for the 3.0L engine:

3.0L Engine

1. Remove the engine appearance cover.
   
2. To access the right bank ignition coils, remove the upper intake manifold..
   
3. Disconnect the electrical connector from the ignition coils.
   
4. Remove the bolts.
   
5. Remove the ignition coils.
   

To install:

1. Replace the ignition coils.
   
2. Connect the electrical connector to the ignition coils.
   
3. Remove the upper intake manifold for the right bank ignition coils.
   
4. Replace the engine appearance cover.
   

P0351 is Ignition Coil A Primary/Secondary Circuit Malfunction.
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
Possible solution - If damage, repair ignition coil circuit - Replaced ignition coil - Replaced PCM or ECM When is the code detected? The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.
P0351 Description: 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.
Hope this helps :)

I searched under 'ignition module' on autozone.com and 'no parts for ignition module' turned up.
I looked under DIS or Distributorless Ignition System and found the coils are inserted in the top of the engine and this tells me that it's likely that the ECM or PCM controls the spark on these cars.

Civic
1.7L Engine

1. Disconnect the negative battery cable.
2. Remove the ignition coil cover (A), disconnect the ignition coil connectors (B), then remove the ignition coils (C).
3. Installation of the ignition coils is the reverse of the removal procedure.

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.

Symptoms:
- 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


P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction.

P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction.

P1391 - Not a valid obd code.
B1391 - Oil Level Switch Circuit Failure
C1391 - Not a valid obd code.
U1391 - Not a valid obd code.
Its possible you may have misread this code. If it is B1391 that would be the only code with 1391 for your vehicle.

P0351 - Ignition Coil A Primary / Secondary Circuit Malfunction. The ignition signal from the Powertrain Control Module or Electronic Control Module 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.

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

P0352 - Ignition Coil B Primary / Secondary Circuit Malfunction.
Same repair info as P0351.

P0353 - Ignition Coil C Primary / Secondary Circuit Malfunction.
Same repair info as P0351



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

P0352 - Ignition Coil B Primary/Secondary Circuit Malfunction
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.

When is the code detected?
The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation

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

Possible solution
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM


Hope helps with this (remember to rate this answer).
