2005 cavalier turns over wont start plugs were no good put new plugs in used dielectric grade on plugs still won't start could I have put to much dielectric grease on plug wires


Trying to start the vehicle is there spark ? Your vehicle has plugs under center of valve cover .Pull the coil pack out , get plug wire cable set and use a spark tester . Check for spark . If plugs were no good you probably fried the ICM - ignition control module . Do you know what and where ICM is ? How to Test the Ignition Coils GM 2 4L Quad 4 The amount of dielectric grease has nothing to do with it .

2004 chevy impala start car runs about10 minutes then stalls new fuel pump when stalls cut out like running out of gas then don't start till cools off if electical to me would cut out instantly help


Not if ignition module . Electronic componets when heated up will act just like that . When it dies check spark, fuel pressure right away an find out what quit . Test don't guess . Videos on youtube on testing GM ignition system. Which engine does yours have ? Had option of two different ones . 3.4 an 3.8L . Ignition module or cranhshaft position sensor could be the cause .
Three dual tower ignition coils are mounted to the ICM, and are serviced individually. The ICM performs the following functions:
• The ICM supplies a power and low reference circuit to the CMP and CKP sensors.
• The ICM determines the correct direction of the crankshaft rotation, and cuts spark and fuel delivery to prevent damage from backfiring if reverse rotation is detected.
• The ICM determines the correct coil triggering sequence, based on how many 18 X ON-OFF pulses occur during a sync pulse. This coil sequencing occurs at start-up, and is remembered by the ICM. After the engine is running, the ICM will continue to trigger the coils without the CKP sync pulse.
• The ICM inputs 18 X and 3 X reference signals to the PCM.
• The 3 X reference signal is also known as the low resolution engine speed signal. This signal is generated by the ICM using an internal divide-by-six circuit. This circuit divides the 18 X signal pulses by 6. This divider circuit will not begin operation without a sync pulse present at start-up, and without 18 X and 3 X reference signals no fuel injection will occur.

No spark on the 98 honda civic ex coupe coil is good and icm is good what else could it be?


If the coil is good and giving out spark and your ICM is good the cap can have a missing button which will not allow spark to go to the spark plugs through the plug wires do replace the distributor cap and rotor and spark plug wires

Where is the ignition module. Can I get to it from under the hood? Should I replace the Crank module when I replace the ignition module?


Hi.

The ICM is located under the hood, next to the coil pack and spark plug wires. Here the part: Pontiac Grand Am Ignition Control Module (ICM).

If you ar having distribution problem and misfire check also the crankshaft position sensor. It signal is used to control coils and sparks.

What should a multimeter read on a continuity test on the coil packs? i'm getting 1.9,1.7,1.7


The multimeter can read the resistance and if it is not open or shorted out, I'd say that your readings are in the normal range, comparing each resistance with each other + or - 10%.

I looked up the resistance readings on my online resource, but they did not list it specifically.
---
I looked up the following on autozone.com:

There are 3 dual-tower ignition coils that are part of the ignition control module (ICM). The ICM contains coil driver circuits that command the coils to operate. The Powertrain Control Module (PCM) controls each dual-tower ignition coil by transmitting timing pulses on the ignition coil control circuit to the ICM for the proper coil to enable a spark event.
  1. Inspect the spark plug wires for proper orientation.
  2. With the ignition OFF, remove the fuel pump relay.
  3. Crank the engine and test for a strong spark on each cylinder spark plug wire using a suitable spark plug tester. Ground the companion cylinder spark plug wire of each cylinder when it is tested.

    If a strong bright blue spark is present on all of the cylinders, remove and inspect all of the spark plugs for proper torque, proper gap, wear, damage, and fouling. Replace the spark plugs if necessary. If there is no spark on any of the cylinders, test the ignition voltage circuit of the Ignition Coil Module (ICM) for an open/high resistance or short to ground, or test the ground circuit of the ICM for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If there is no spark on any of the cylinders, or spark is weak or intermittent, test the IC circuit for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If spark is present on one or more of the cylinders, inspect and test the spark plug wires for arching, cuts, rubbing on other components, and proper resistance. If all tests are normal, then the system is operating correctly.

How do you remove the ignition coil


Each ignition control module (ICM) has the following circuits:
An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.

To install:

CAUTION DO NOT wipe grease from the module or coil if the same module is to be replaced. If a new module is to be installed, a package of silicone grease will be included with the module. Spread the grease on the metal face of the module and on the cover where the module seats. This grease is necessary for module cooling.

You could have a problem on the camshaft sensor. If the camshaft sensor is inop, you will not get any spark. The sensor tells the computer what timing is set at, so the coils fire properly. Check that first.
