I am trying to replace my camshaft position sensor, but a fuel injector is in the way. Do I need to depressure the fuel system, before removing the fuel rail/injectors? And how?

 

Maybe we can save you some work.
Would you mind telling us why you need to remove the cam sensor?
The reason I ask is because there are several things that can cause a cam sensor code to come up and if we knew that might be the reason, you could be in your way to a wild goose chase.
Interested?

 

my car has had two episodes of stalling out while driving (about two weeks apart). Usually when I’m going real slow. During those two episodes, I could start my car, but it would stall out again after about 10-20 seconds. The following days after those occurrences, my car drives fine. I took it to autozone and a camshaft sensor code came up. I also took it to a Meineke for a diag and they think the stalling is due to sensor wearing out.

 

What engine is in your vehicle?

Do you have the code(s) they obtained?
I can tell you how to depressurize the fuel system, You can either pull the fuel pump fuse while the engine is running and it will stop because it ran out of fuel, or you could smack the inertia switch and it will interrupt power to the fuel pump removing any pressure in the fuel system then when done just depress it and reset it.
You should be aware that if you remove a fuel injector, you should replace the "O" rings on it because it can leak later.This can be a lot of work , if you are not correcting the real problem.


What will you do after you replace the sensor and you still have the same problem?

Replacing good parts can get expensive and time consuming.
When we get an intermittent problem like this , a scan tool can bring up "Freeze Frame" info. That can tell us what the operating conditions were at the time the engine stalled and a code has been set. An experienced tech is better able to pin down after examining which condition is not right and go from there.

I can understand wanting to help yourself, but hopefully preventing you from throwing away some time and hard earned $$$.

If you want to give the sensor a shot , go for it. Let us know how you make out with this , OK, thanks.
