Can someone help me , van won't turn over or click and the ignition works fine, the immobilizer light doesn't go off. When I turn the key off a few lights stay on dimly lit. What make things worse is I removed a cobra alarm that was spliced into the canbus ,I was really careful and the cables that are used to cut the starter circuit were not connected into it.

If the immobiliser light didn't go out correctly when the problem first occured, then I suspect that was what needed addressing rather than the Cobra alarm system, so now it is quite possible you have introduced a second fault into the system.
Although I quite agree with you about aftermarket alarms and they often are a cause of issues as generally not built to last as well as the factory set up.
Basically if the immobiliser light comes on with ignition , but doesn't go out before turning the key to start then no way will the engine start, regardless of any other issues.
Have you tried any spare key or had a good locksmith check it out? Note the word "good".
Generally I think engine will turn over but not try to fire up with factory immobiliser if light stays on.
I don't know about the Cobra system.
If you have a full version of MES it should tell you more, many on Forum MES section can advise on that, I don't use it as when I was buying I had to have MaxiEcu version as MES didn't recognise the Fiat Scudo with Peugeot 2.0 engine.
I doubt if that is the answer, sorry.
Mmmmm!
Still maintain you need to get the factory immobiliser light to come on with the chipped key turned on, then go off before ignition turned to start for the factory immobiliser to de activate.
I know nothing about the Cobra system and am not a fan of aftermarket alarms as generally fail prematurely.
Can Bus wiring is generally a "twisted pair" of wires and if interferred with can cause problems meaning the ECU/BCM can have trouble reading them.
So i have been disconnecting the battery often as I'm still waiting on a new battery and last night I left it connected overnight and gave it a try, today and it started first time . So glad as I was worried that I caused more problems than I needed
I have generally found a good auto locksmith can program new keys with his laptop etc. including for Fiat Punto Evos etc.
