What you just replaced was the cam sensor (also called a stator). Either it's not indexed properly in the distributor or you have the distributor in a tooth off. As the distributor isn't adjustable, you can't turn it to compensate. The item you intended to replace is the crank sensor which is located on the drivers side of the bellhousing at about 11 o'clock looking from the rear. I can't remember the exact indexing procedure for the sensor you changed but likely you already have a manual that shows the way it's installed. I do remember something about using an alignment pin while installing to keep the part where it belongs. Shutting down while driving is a symptom common to both those sensors as well as the fuel pump. However, other sensors need to be tested as well just to be sure. Have the system scanned and see if any codes are stored. Manuals also outline individual component tests that can be done using a digital ohmeter.

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 (knock sensor) crank position sensor...is just behind the harmonic balancer, (lowest pulley on the motor) on the block, usually on the left side.
i would check the coil first though. sounds to me like a no spark issue.

Wat does code po320 means f150 2002


Here is the general definition.

P0320 FORD Description Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM) detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.
Possible causes - Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)
