If the fuel is more than a couple of years old, then you'll need to either drain it & fill it with fresh fuel, or at least dilute it by 50% with some decent non-ethanol 95 (ie if there's 20L in the tank, put 20L of fresh 95 into it).

You should be able to get the fuel pump running manually to pump out the old fuel (remove the line from the fuel rail & jam it into a larger hose, that can run down to a jerry can, 20L drum, or other decent size fuel-compatible container.

When cranking, you've got spark - that's good - most immobilisers kill either spark or fuel. You may need to "hotwire" the pump like you did & try it again.

However, if the immobiliser was fitted by a clever person, they may be killing the injectors - either by working off the injector relay, or through the computer output (+ side is via a relay, and on at all times, and the negative side is triggered by the computer). Simple test is to grab an injector between your finger & thumb, and feel if it's clicking. If not, then check for 12V+ in the terminals with the ignition on - at least one of them should be 12V+ - and often it's a red wire.
