Some 2litre TS questions needing answers

Hi Lads,

I bought my 2 litre last november and only now am getting a chance to start on it due to other projects.

I have a few questions you might be able to help with. ITs a 1991 model so one of the last. The car isnt starting. The crank is turning over fine but it just wont start. There are a few possibilities so here goes,

First question I have is I am the third owner but the original owner fitted a Pyranha model immobiliser but the lad i bought it from assured me it has been bypassed so today I traced the wiring and found it comes in behind the main fuse board at the drivers side but some cables go off over to the passenger side and are wrapped (fibres are twisted together) onto some other cables over there, some go off under the insulation, others are earth, others are sent to the dashboard LED etc. so even if it wasnt switched off am I ok to just disconnect and remove all associated cabling (not snip). If the immobiliser is still active is simply disconnecting it at the box or removing the cabling enough to get the car started if the immobiliser is the problem? Also some cables were connected to the small set of relays in the engine bay, I removed them and bundled up the left over cabling, I presume this is ok as it is? you can see the immobilisor in the top corner

next question is there is only one vacuum cable but should there be two? also the one thats there is all split and needs to be replaced, is it necessary to get the enigne started?

I tried removing the whole air intake system from the filter up\to the manifolds but it seems the fuel relay is in my way so i tried removing that but got as far as removing the two nuts holding it to the engine but how do i get the fuel hoses themselves out of the engine? There is one nut just under the relay holding the air manifold on and i have to remove the fuel relay to get it but cant get the fuel hoses out, also the rubber pipes connecting the air manifold to the engine are perishing so are they easy to get replacements?

Lastly is there a recommended list of replacements for a full or proper service? other than the obvius oil and filters? I have noticed the rotor arms and dizzy caps are worn so shold I replace the HT leads, dizzy caps and rotor arms? I have done the sparks but think my problem could be with the ignition system

sorry for the longwinded description but I was all day today at this and got nowhere

Dont bend the rules, Rule the bends

Mate, I'm not a specialist on these engines, but an engine is an engine.

Regarding the immobilizer, I'm prety sure that by removing it completely you loose any chance you get of firing up the engine. So no, stick with it.

First of all, do you have sparks on your spark plugs ?

Secondly, do you have fuel coming in your fuel rail ?

Third, are your injectors working or are they stuck ? ( you should hear them click when you you give them 12v )

If all of the above are ok, then your car should start, immobilizer or not.

If the immobilizer is active, its either cutting off power to the injectors or the coil.

When you switch the ignition on you should here some of those relays you pictured click in. 1 is for the motronic unit and that needs to switch on with the ignition.Another is for the fuel pump.
The fuel pump starts once the flap in the air flow meter opens up. Cranking sucks in enough air to move the flap and starts the pump. If the flap is stuck then you won't get fuel.You could gently move the flap with the ignition on to see if the pump starts.
Try cranking with one of the HT leads removed from the distributor and put near to an earth to check for sparks.l
