Symptoms of a bad crank sensor is hard starting, no starting or rough idle. If you're able to start the engine, and it runs for a few minutes or seconds and then dies out, most likely it's a bad crank position sensor. Also, there may be no spark in some of the spark plugs.
no spark, no start
car will not start if the crank shaft positing sensor is bad ..because it control the car spark plug firing..( no fire no start )
IF IT IS A 4 CYL YOU PROBABLY HAVE A BAD CRANK SENSOR OR IGNITION MODULE.
if your crank position sensor is bad you car or truck will not start because you will not have spark
Most likely: 1. bad battery connection + or ground 2. bad coil or wires 3. bad cam/crank sensor
You will have a no spark situation. Testing it with a volt meter is easy. Twist the crank shaft slowly by hand and watch volt meter. If there is voltage and no voltage the sensor is good. No readings sensor is bad
The crank sensor sends a signal to control the spark timing to the engine. If the sensor goes bad the engine may run rough or not run at all.
If you have a bad cam sensor there will be no input sent to the computer signaling the position of the cam/crank...etc, and there will be no signal sent to the coils telling them to fire. So yes, a bad cam sensor will in part cause no spark. Try a new sensor, or pick one up for cheap from a junkyard.
Check the Sonoma crank position first. If the sensor is bad then there will be no spark from the coil.
yes but the cam sensor and the crank sensor work to geather so make sure to have it tested if you can to make sure wich is bad .
No but, if the crank sensor goes bad you lose the fuel pump and spark.
