Driving down the rode fine and out of nowhere car lost all power to the engine. Cranks over but will not start. Sounds weird like the starter is cranking the engine and thats the only thing happening.
Do you
have the same problem?

If the engine sounds weird when it's cranking, then you may have broken a timing belt and on that car, that would be fatal for the engine. Either check the belt or take a compression test.

OK, you need to do some more testing.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Please post the compression and fuel pressure readings when you have completed all the tests.

I dont have the proper tools to do the pressure testing so I hooked a code reader up and got a P0340 Camshaft Position Sensor.
If I pull the spark plug out and feel air blowing out when cranking, It wouldnt be the timing chain would it?
Thank you for your advice. Very much appreciated.

Did you find the problem, I am having the same issue and it says it is the Camshaft position sensor.I replaced that and still nothing. I am at a loss on what to do. I need my car and it wont start. Looking for any help I can get
