No, not camshaft sensor: crankshaft sensor, much harder to access sadly.

Vertically below throttle body, mounted in engine block, 'looking' at back of flywheel.

This looks tough. Is this shot from top of the engine bay or from bottom? What are those 3 voids?

That's a photo of the back of the engine, taken when not in vehicle. Voids are the intake ports.

Damn. I am not how to reach this from top. Will remove the air intake pipe and see if I can reach. Will update if I make some headway. Do suggest an approach if you can think of any. Thanks

 

Easier, but still not easy, from below, I think.

 

USB endoscope-type camera can be helpful.

Connected the temp pins, physically checked all connections. opened up air filter box, filter was clean but the paper was in bad shape. Opened up the hoses and cleaned the throttle body. Throttle body wasn't that dirty. 
Cranked the engine and lo it fired. RPM meter went up and then it died. Sprayed some throttle body cleaner into the throttle body and it fired again but did not sustain.
No fault codes showed up after this brief firing session. 
I suspect the fuel supply is an issue, let me know your views. I was mighty relieved to hear the engine crank. OBD port was plugged in but wasn't able to log any data, will configure the software and log again.

Let me know where I should should look next to get the firing sustained. Thanks

Is this correct way to take of the fuel supply lines?

Probably,  I can't remember it being difficult.

Downloaded the log from the firing today. There is not RPM recorded however, the RPM need in the dashboard moved and so did the needle in the torque pro app. Probably this was just too short a duration or for reasons best to the app the RPM is not recorded. I suppose you are right about the sensor being disconnected but if that is the case is there any other source from where the app and dashboard draws the RPM reading?

Unable to work on the car due to continuous heavy rains for last 2 days. The extra thinking time is now convincing me that the issue is with the fuel supply. Will start inspecting as soon as the weather clears up. Planning to manually add 5 litres to the tank and also some additive to clear the clogging in the line. Do share your suggestions. Thanks

So the rains have let up and got a chance to work on the car. The fuel indicator is showing nothing, which it was doing so previously.  The app connected via OBD port is showing open loop to the fuel supply.

Is it that I have now choked the fuel filter or has the fuel pump failed. How do I check this. Do share pointers for this resolution.

The fuel line in the engine bay is dry and I cannot smell any petrol in it. There is probably nothing coming from the tank. The engine cranks and fires if I spray cleaner in the air intake.

Can you hear the fuel pump running?

 

The LH diagram is the petrol engine.

That is what I am not sure of. There was so much ambient noise that I just could. Tmrw morning, I shall try again. 
Also, got this video, MK2 looks almost like this. Will check for voltage and take it from there 

 

Any tricks on how to open the plastic cap for the filter. I do not have the opening tools and let me know if someone has a hack to open this. Thanks

My Fabia has a fuel filter in the fuel line.  As far as I know, the pump has the level sensor included but not a filter. That video you posted is for a diesel.

I think he means the lock ring on the fuel tank under the back seat, the clue is the video posted above!

 

No, there's no hack, the lock ring is incredibly tight and even if you get it off you won't get it back on again without the correct tooling.

 

If you don't have the right tools you can't work on cars!

Correct. I posted it to confirm if the disassembly is similar. I do understand that the versions are different.

Yes, right tools is half the job. The issue is that this tool is not available in India and was hoping for an alternate tool which might fit. Fabricating one is very difficult but will get it done if that is what it takes. Thanks

 

Two people, each with block of wood and hammer; opposite sides of ring, co-ordinate timing to hit at same time.

I have always released them with a hammer/mallet and hardwood drift.

 

Petes dual approach would be much better but I am always working on my own.

 

I have never found the removal difficult.

Block of wood locked into the notches I suppose. Will be challenge to find a willing partner. In India DIY is frowned upon for some reason. People from my apartment building find it amusing that I work on my car. Will attempt solo and see if it works. If it does not work, will make the tool. In India the tool cost about 500 Euro which isn't worth it for one time use. Will update on the progress soon. Thanks for the tip

That is true. The final landed cost to me is about 500 Euro which seems excessive for a tool which will be used once. Will attempt the wooden hack as suggested.

This is encouraging. I to work alone and knowing it is possible really helps. Thanks. Will attempt and post with pictures soon. Have got the tools to siphon the fuel before opening the tank up and waiting for the rains to let up. It has been pouring here for a week non stop.

I have removed several of them and never encountered any significant resistance, I did not give it a second thought and just got on with it, what thousands of mechanics do instinctively every day when faced with a new situation thousands of others debate for hours on how to go about it or to shy away from the job. Someone with experience making their living is not going to waste time like that or walk away.

 

The worst that could happen is you break off one lug and you then have several others to attack knowing the maximum force, even if it did fracture it would still tighten down and seal the joint to a degree and you can buy replacements.

 

In this instance I am going to disagree with Sepulchrave, but that is based on my successful experience but he may well have encountered more resistant or inaccessible ones.
