QUESTION: Has anyone VERIFIED it's the Crank Sensor? Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.
If you find P0335 - Crankshaft position sensor circuit malfunction, then I'd say they are correct (after you eliminate wiring/connections as the cause).

96 non turbo diesel turning over but wont start,why?

Probably not. One of the pulleys that is not turning is a vacuum pump. You need that part to work and it must turn. Most of the timing parts run off of a heavier chain.

Some sensors are mounted around the crankshaft and/or camshaft. When a belt breaks it can pull off small sensor wires and even break the sensors.

Help with my 98 camaro

hi, are you saying when you turn the key to start the car nothing happens and it dont even turn the engine over so it can try to start if you mean this then you need to start thinking of starter motor problems and replace if needed.

now if your engine is turning over but it wont fire up then this could be crankshaft sensor, faulty ecu, faulty coil, it could be a number of things you could throw money at it and not find the fault your best bet would be a diagnostic check done to see what codes where thrown up as having errors this would then give you the exact fault and would save you wasting money on parts you may not need

Your crankshaft sensor doesn't always make the light blink. I'm almost positive it your crankshaft sensor.

Seat toledo v5 wont start just turns over

If there is a problem with the crankshaft sensor then when you attempt to start it the ecm cannot confirm when number one cylinder is on top-dead-center thus not activate the 'open loop' part of the engine controller. I think the reason that it was running fine then would not start was because the only time the crankshaft sensor is used is when starting, not after while in closed loop.

2000 SL2 wont start

Need to do a compression test to see if all 4 cylinders are operating properly. A loss of engine power is usually a result of wear on internal engine rings and seals.
