Do a 2004 Envoy SLT 4.2L have a Ignition Module?


Crankshaft position sensor,cam sensor . your vehicle should have coil on plug , a coil at each spark plug !
Ignition Coils
Each ignition coil has an ignition 1 feed and a ground. The PCM supplies an ignition control (IC) circuit. Each ignition coil contains a solid state driver module as its primary element. The powertrain control module (PCM) signals the coil driver to initiate a firing event by applying a signal to the IC circuit at the appropriate time. When the signal is removed, the coil fires the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.
During normal operation the powertrain control module (PCM) controls all ignition functions. If either the crankshaft position (CKP) or camshaft position (CMP) sensor signal is lost, the engine will continue to run because the PCM will default to a limp home mode using the remaining sensor input. As mentioned above, each coil is internally protected against damage from excessive voltage. If one or more coils were to fail in this manner, a misfiring condition would result. Diagnostic trouble codes are available to accurately diagnose the ignition system with a scan tool.
If a crank sensor is replaced a Crankshaft Position System Variation Learn must be done and a scan tool is need to do this.

97 oldsmobile achieva wont fire changed coil pack spark plugs cam sensor still wont start


Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you having a problem with more than one system, I want to check for rpm signal, that usually comes from the crank sensor. Not sure why you replaced cam sensor? I always want to check sensor wiring circuits before replacing anything. Don't replace anything unless your testing points in that direction.

I took care the check engine light now I have no spark. I took the plugs out and made sure I had agood ground and no spark


spark is allowed by the following items
crank position sensor
cam shaft position sensor
immobilizer
ignition control module
check that what you did to fix the engine light didn't intere with something else

Where is the ignition control module located in a 2007 Malibu?


What engine does yours have ? 2.2 , 3.5 or a 3.9 L , there isn't an ignition control module . The engine control module (ECM) controls all ignition system functions, and constantly corrects the spark timing. The ECM monitors information from various sensor inputs .
Now , what seams to be the problem ? No spark ? Crankshaft position sensor could be the problem or cam position sensor .
Now ,what

No spark on cyl 3 and 4


What engine ? 2.2 l or 2.4 L. You don't say if any codes are set. no P0303 - P0304 cylinder's 3 & 4 misfire ? or any other ? No the cam sensor wouldn't cause just two cylinders to misfire. The PCM triggers the ICM to turn on an off coil's to build up an collapse the primary voltage inducing the secondary voltage . This engine is equipped with a non-distributor ignition system called the electronic ignition (EI) system. The primary circuit of the EI system consists of the following components:
?€¢
Two separate ignition coils

?€¢
An electronic ignition control module (ICM)

?€¢
A crankshaft position (CKP) sensor

?€¢
Related connecting wires

?€¢
The ignition control (IC) portion of the powertrain control module (PCM)
Important: The camshaft position (CMP) sensor is only used for a misfire detection. It is not part of the ignition system. !

I have 88 chevrolet corsica. No spark at the plug wire put new coils / module on still no spark can the crankshaft position sensor stop it from getting spark and i checked all te fuses Bill


Yes the cam sensor could fail to send a signal to the ignition module, but a V6 engine does not use a cam sensor.
It does use a crank sensor.
You would need to know that the ignition module and coils have battery voltage, then you would need a book to give you the test procedures for the computer and crank sensor.

Got no spark to the ignition system


what is the make and module? It depends on the make ,but use a crank position sensor or a cam position sensor to supple spark to the ignition control module

My engine turns but no spark I changed ignition coil and still no spark,what could it be?


Depending on which engine your car is equipped with; the following components could be at fault.

Crankshaft Position Sensor
Camshaft Position Sensor
ECM (Engine Control Module)
Distributor Cap or Rotor
Fouled Spark Plugs
Bad Plug Wires

If they haven't been replaced in the last 30K miles, I suggest you check and /or replace the the plugs and wires first.

If your engine is equipped with a distributor, check and/or replace the distributor cap and rotor if it hasn't been replaced in the last 30k miles.

If your engine is equipped with crank or cam sensors have them tested.

There is no spark thus car won't start. the battery is fine, it turns over good, it is not flooded, the spark plugs are new, the ignition coil was just replaced, what else controls the spark


The Crankshaft Position Sensor and the Ignition Control Module also control the spark. It depends on whether your vehicle is equipped with the 2.2L engine or the 2.4L engine as to where these components are located and what they look like.
