Pontiac Problems? Ask a Mechanic for Answers ASAP
hello, my name is ***** ***** I will be glad to assist you. please allow me a couple of minutes to gather some basic info.Roy
when you crank the engine does the tach move up a little bit???
do you have a scan tool to read cranking rpm???
checking the crank sensor signal.
did you make sure the cam sensor connector is tight and clean???
are you there
When I turn the key to on it goes from below 0 to 0 but when I crank it doesn't move at all. No tool to check cranking rpm, what do I need to do to check the crank sensor signal it is plugged in tight but I didn't check if it was clean as we didn't unplug it during the head gasket set change
you need a scan tool to see if the pcm is getting a crank signal from the sensor. if it does not get a signal there will be no spark.
inspect the harness for any damage. it goes to the icm as you had it off for the job. check the cam sensor as well. it is on the timing cover.
Would the icm still pass testing with a multimeter if the crank sensor was bad? We did test the ICM and it passed the test.
icm test with voltmeter??? that only means it has power into it. it does not verify it is working.
you can remove it and take it to a parts store and they can test it to be sure it is working. that is a free service.
Having the ICM tested right now. Crank sensor is clean and connected well.
