Need help Please! 2002 Nissan Sentra won't start Sign In

Hello all need some help please...

So my 2002 Nissan Sentra recently won't start. The key turns over and it sounds like my car wants to start for a second but doesn't. I checked all the hoses under my hood and realized I had one that wasn't connected to anything on one end. I attached some photos for reference. I have reason to believe it has to get connected somewhere near the brake booster or intake manifold?... but then again I don't know much, and why I am here.
The red circle on the 2nd photo is where the one end of the hose is connected to. Thanks for the help!!!!

Don't worry about that. It looks like it's just a vent hose that


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.

Any way to check for codes - yes even if CEL is off.

What or who has been messing with this. Follow HT's list of a no start and Kev2s suggestion for codes.
* Pic #1 what you are hold does seem like a vent hose only but there's another below that I think going no place?
* Pic #2 Where is the other end of those wires to plug just cut off? Appears to be cut off to get a new plug?
Is this your car or just one that doesn't start and curious?
