Nissan Primera P11 GT won't start!

hi everyone thanks for your help on my other topic's but i have another problem with my s reg primera gt the problem is it's been stood for 3 months and my mate change the battery with disconecting the nats alarm in the boot with the key fob and now the car won't start the fuel pumps working when turn the key and it's sparking but the injectors arn't kicking in and the little red led light above the glove box isn't working any ideas.

I have a sneaking suspicion that Primera fuel pumps can struggle to refill the fuel line up to the engine if fuel has drained back to the tank over a longish period of time of the car not being used.  Try turning the key loads of times without turning the engine, so as to prime the fuel a lot.  Then try to start it - if it fires a few times then you're on the right track and with a bit of luck you'll get it going.  Hopefully the red light isn't too significant.

i dont know if it has one or not but cud be the imobiliser

sounds like it could be flooded,

I take it all teh connections are on there? you checked for spark, fuel etc at the engine?

don;t think the imoby controls the injectors it;s usually on the CAS that the imboy affects (ie no spark)
