1999 chevy blazer will not start. No spark!?!? No spark from the coil to ground.


Could be a bad coil, bad Ignition Control Module (what controls the ignition coil as commanded by the engine computer), or a bad crank position sensor, or cam position sensor. Or the wiring and circuits to all the ignition parts.
Often it is the crank sensor (CKP sensor)-The pcm must have this information from the crank sensor to determine spark timing. If no good signal from the crank sensor, there will be no spark.

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.

The diagnostic test shows no signal from camshaft sensor. I checked all the wires for breaks, and I replaced the camshaft sensor code (0340). The car turns over good, but it will not start. Any ideas as to...


Cam sensor? or Crank sensor? I know that the generic definition of DTC P0340 is "No cam signal at PCM" however, a crank sensor can also be the cause of this code.

A cam sensor normally will not cause a no-start. I can cause a long crank time before starting. The cam sensor signal is only used to sync the fuel injectors. If there is no cam sensor signal the computer will start firing all of the injectors on every revolution of the crankshaft to get the engine running. A crank sensor, however, will cause a no-start condition because it is used to control spark. If there is no crank signal there is no spark...period.

Part of the troubleshooting chart for DTC P0340 on your vehicle includes inspection of the crank sensor and checking for the crank sensor signal at the Powertrain Control Module.

1996 Jeep Grand Cherokee No Start


I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

1990 gmc 6500 topkick with no spark or injector pulse. all 4 wires on the ignition coil have battery voltage with key on. is coil shorted or is the ignition module bad?


You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.

My 1998 ford escort won't get sprk through cylinder 1 and 4


Make sure cam and crank sensor are active. pcm must see these signals before allowing primary part of coil pack to energize. crank sensor will be possible suspect,usually located on engine to bell housing. flexplate or flywheel is the reluctor wheel or like a shutter wheel for the sensor to identify the position of crank for spark delivery. see if you have voltage at harness to coilpack with key on? if not you have another problem.

Car has no spark or injector pulse(new ecm,crank sensor)


Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

I cant get spark out of the coil pack


cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.

1999 Chevy tahoe will not start


check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

No fuel injectors, intermittently


With the key on, do you have voltage at fuel injector, use a test light?
Engine cranking do you have spark at the spark plugs? I'm just trying to see if you have more than one problem? I don't know how much testing you have done?
Is there a purple wire with white tracer at ignition module, Engine cranking, there should be a dc pulse on that wire? If not, the computer won't ground the fuel injectors. In my opinion.
