No spark...changed ignition control module and still doesn't work

Ignition Coils/Modules
The electronic ignition system uses an individual ignition coil for each cylinder. There are two separate ignition module assemblies located in the camshaft cover of each cylinder bank. Each ignition module assembly contains an ignition control module and four ignition coils. Each ignition coil connects directly to a spark plug using a boot. This arrangement eliminates the need for secondary ignition wires. The ignition module assemblies receive power from a fused ignition feed. Both ignition module assemblies connect to chassis ground. A Reference Low and four ignition control (IC) circuits connect each ignition module assembly to the PCM. The PCM uses the individual IC circuits to control coil sequencing and spark timing for each ignition coil. The IC circuits transmit timing pulses from the PCM to the ignition control module to trigger the ignition coil and fire the spark plug. The PCM controls ignition system sequencing and timing events

Hi, Spark is controlled by the computer. Where and when(timing). You can not change that. Each cylinder has 1 coil and spark plug. That module is built in to the computer. There are sensors around the engine that send info to the computer. Air, spark, timing, and fuel. When these things work properly the engine will run.

P0353 CHEVROLET Description The ignition system on the vehicle uses individual ignition coils for each cylinder. The Powertrain Control Module (PCM) controls each ignition coil operation. The PCM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.

Possible Causes - Ignition Coil harness is open or shorted
- Ignition Coil circuit poor electrical connection
- Faulty Ignition Coil 3
- Faulty Powertrain Control Module (PCM)

you may have a bad crank sensor. this sensor tells the module when to spark.just be sure to check for proper voltages and grounds at the coil and the ignition module.

It could be a couple of reasons but from my experience in most cases you are looking at a bad ignition control module. If you are not getting ANY spark at all to the spark plugs. I'm not saying just go and replace it because it could be a number of things like a bad ECM or the fuse going to the ECM or even a bad camshaft position sensor. The ignition control module costs about $70.00 and like I said is the most common but check the others first. I would start at the fuses. The ignition control module is mounted on the side of the distributer and I gave you a picture below of what one looks like for your vehicle. I hope this helps and good luck.

Did you replace the igniter (inside the distributer) and the ignition control module (on top of the distributer. Sometimes the control module gets overlooked...

Make sure it is not firing.Since you installed the ignition module,the plugs may be fouled out by fuel.If so,replace the spark plugs,and it will start.If there is no spark,the stater in the distributor will be the most likely problem.The stater is the other part that goes out,if the ignition module doesn`t.I hope this helps,let me know if I can help you any more.

Removal Procedure

1. Remove all the electrical connectors at the ignition control module.
2. Note position of spark plug wires for installation
3. Remove the spark plug wires from ignition coils.
4. Remove the screws securing coil assemblies to ignition control module.
5. Disconnect coils from ignition control module. Installation Procedure
   
   1. Install the coils to ignition control module.
   2. Install the screws and tighten to 4-5 Nm (36-44 lb. in.) .
   3. Install the fasteners securing assembly to engine and tighten to 8 Nm (70 lb. in.) .
   4. Install the spark plug wires as noted during removal.
   5. Install the electrical connectors to the ignition control module
6. Hope this Helps !
