Spikes T4 single cab

[Spike]

Hey all, I'm another one from the mk2/Air cooled side. Just picked up my first vw van. A 98 t4 single cab. It seems fairly solid but does have a few issues.

The major one atm is the immobiliser, I have a new ignition switch in the post, turns out the old one still works. Possibly need a new ignition barrel as well.
The car will start and cut out soon after, using the original key. I'm leaning toward an immobiliser bypass.
