Go to a library that has a set of the factory service manuals (not Chlton's or Haynes or Motor's). The FSM's will give you all the trouble hotting charts that the dealer techs use.

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.

2000 318 ram van wont start new ecm sensors got spark gas


If you are getting spark to the plugs and fuel spray, and you have compression and the spark is at the right time, you should have explosion.
Is it possible the valve timing is off - timing chain issues ?
Are the new plugs fuel-fouled ?

Audi 100s 1993 cranks doesn,t start, turns over no start. when it starts runs rough and stalls.


could very well be a faulty sensor, leaky vaccum hose, bad coil packs, needing of new fuel filter, spark plugs, wires.

Have you checked your fuel pressure to make sure it is good. You can do this with fuel pressure tester on the fuel rail.

Also check every cylinder for spark
If you don't have any spark, or very weak spark, you could have bad coil pack, module, or crank sensor.

You can remove one plug at a time, and place it back on plug wire, place it on top of engine block, have someone else turn motor over well you observe to see if there is spark.

Do you have a service or check engine light on? If so, I would have the engine codes read to pinpoint exact problem area.

Let me know if you have any questions or need further help
