Jimny no spark or fuel

Hi all, at a bit of a loss with my jimny. Just replaced the head gasket and now I have no spark and no fuel. I can't hear the lift pump when turning the key. On cranking the rev gauge does not move. From what I've read online most people point towards an immobiliser fault but I'm not getting a padlock on the dash and as far as I can see mine isn't fitted with a crank position sensor. Truckette is a t reg fitted with a g13bb engine, anyone got any ideas or could drop some knowledge on me? Much appreciated, thanks

Just recently did my G13BB head gasket, I can only offer the checks I would do.

Timing marks on crank and cam are lined up properly with the timing belt on?
Spray contact cleaner on all the sensor connectors and let dry and plug back in.
Make sure cam sensor connector is clean and connected properly
From there its a matter of checking wiring carefully, check 5V rail is there for the sensors
Might be good to check ECM connection is clean and has good contact to the wires.
Clean up the earth points make sure good connection
Vacuum hoses in good nick and all connected.

Not sure , if the camshaft sensor fails does that shut down the fuel and spark at ECM? I know its different from a crank angle sensor which will often do that but not sure with these engines.

I went through everything obvious, cleaned and rechecked every connection, when I'm next in the workshop I'll check continuity across the plugs. 3 earths (on starter, stat housing and bulkhead) have been cleaned and remade, timing is spot on, only thing I could see is the lambda sensor cable is a little strained but not excessively.
The smaller of the 2 vac hoses broke off of the air resiviour and is on my to do list but surely that won't shut it down??
With the rev gauge reading nothing on cranking is it pointing towards cam sensor or ecm?
