AnswerYes, but, if the sensor is permenately bad it probably wouldn't start again. It is , however, possible that it has an intermittent problem, causing it to stall, buck, or misfire. it could also have contamination on the flange (the part on the crank pulley), oil saturated wiring, or loose /shorting out wires. a visual inspection of under the timing cover will help.

If it stalls and restarts right away, check more into fuel pump problems and airflow monitoring systems, possibly even injector pulse (cam sensor related).

If it simply dies without hesitating, I'd guess your crank sensor.

The sensors can be checked with an oscilliscope, graphing multimeter or for frequency(not anywhere near as good). Resistance values are meaningless with the type of sensor used.

I am working on the same problem in a 1999 Elantra Wagon, and have read that it could be the crank sensor. Hope this helps. here are a couple of possiblities: bad crank sensor, broken or jumped timing belt, bad fuel pump, bad cam sensor. Answer was this the only problem or was the transmission not shifting before too?

A bad cam or crank sensor can cause a no start, but the engine will still crank or turn over.

Probably need to check the crank sensor (if the check engine light is on) or the fuel pump... I had that problem not too long ago...

Most dealers will charge 1 - 1.5 hours. This includes the diag time to make sure is is just the sensor.

A faulty crank sensor would cause no spark and no fuel.

It is located underneath timing belt cover, behind crank pulley.
