I have a 99 Yukon that was doing the same thing. My problem was the security system. Is the security light flashing when trying to start or before you crank it? there was a lot of problems with 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.

How do replace ignition control module in 1998 K-1500 5.0 liter vortec


This system does not use the ignition module used on the DI systems in the past. The VCM controller now controls the ignition control (IC) and bypass functions.
The crankshaft sensor, located in the front engine cover, is perpendicular to a target wheel attached to the crankshaft. The target wheel is equipped with slots situated 60 degrees apart. As the crankshaft rotates, the target wheel rotates past the crankshaft position sensor. The rising and falling edges created by the slots cause a signal to be sent back to the VCM. This signal occurs three times per crankshaft revolution and is referred to as the 3x signal for V6 applications. The signal occurs four times per crankshaft revolution and is referred to as the 4x signal for V8 applications.
The VCM then utilizes this 3x (V6) or 4x (V8) signal in order to provide the correct spark to the engine by way of the single coil driver module. The single coil driver module is basically an electronic switch that when commanded by the VCM, causes the primary coil voltage to breakdown, energizing the secondary coil and providing a spark via the coil wire to the distributor cap. The distributor consists of the following components:
The system consists of the following components:
?€¢
Vehicle control module (VCM)


?€¢
Distributor


?€¢
Ignition coil driver module


?€¢
Ignition coil


?€¢
Crankshaft position (CKP) sensor


Now which part do you want to replace ?

?€¢
Cap and rotor


?€¢
Camshaft position sensor


?€¢
Gear drive and shaft

The camshaft drives the distributor shaft which rotates providing a spark to the correct cylinder by way of the cap and rotor. The camshaft position (CMP) sensor functions much like the crankshaft sensor previously described but provides only a 1x signal to the VCM. That is, for every 2 rotations of the crankshaft, there is 1 rotation of the camshaft. Note that the camshaft position sensor will not affect driveability. The sole purpose of the camshaft position sensor is to provide the VCM with the necessary information for the misfire diagnostic trouble codes (DTCs).

I've replaced everything to do with ignition spark on ky 1998 gmc pickup it has a 350 vortech engine why am I jot getting spark at the spark plugs ?


There is a spark control modal in the distributor most books do not tell you about it . if you have replaced everything else try that

I have fuel but no spark. what can it be?


it could be a crank sensor, ignition module, coil, if this has a distributor could be pickup coil or a bad distributor, bad cap/rotor. could also be a PCM problem on the ignition circuit.

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.

I have a po 300 engine code random cylinder misfire i change cap rotor and wires problem still exists


PO300 - Random/Multiple Cylinder Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

Causes:
- Improper spark plug
- Insufficient compression
- Incorrect fuel pressure
- The injector circuit is open or shorted
- Fuel injectors may be faulty
- Intake air leak
- The ignition signal circuit is open or shorted

Solutions:
- Perform Injector Service
- Replace Spark Plugs
- Replace Injectors
- Replace Ignition Coils

  • Incorrect ignition timing
  • Vacuum leak(s)
  • Low or weak fuel pressure
  • Improperly functioning EGR system
  • Defective Mass Air Flow Sensor
  • Defective Crankshaft and/or Camshaft Sensor
  • Defective Throttle Position Sensor
  • Mechanical engine problems (i.e.-low compression, leaking head gasket(s), or valve problems
Common Misdiagnoses

93 toyota celica gt. engine turns over but wont spark.plugs new wires and cap and rotor good, put ohms meter on coil and secondary output and is in specified range but have no power to coil.changed ignitor...


My experience with Bosch ignition system (found on european cars) is the spark control is sent by the ignition module. The ignition module has to receive an input usually from a crankshaft sensor. This is usually near the crankshaft pulley on many cars. I am currently working on a 04 Toyota RAV4 and it has exactly that. If your sensor wiring gets loose or a bad wire then the computer won't signal for spark. This may not be your problem but it sounds like it probably is.
(By the way on my Alfa Romeo it is a sensor around the bell housing that senses the teeth on the flywheel) Good luck!

I have a 1996 GMC yukon with 5.7 engine it is not firing I have changed the coil this did not fix problem what do I check next


Check for injector pulse if no pulse with no spark check ignition module in distributor or crank sensor.
