Im trying to start up my 325 but its just cranking but not starting.

Its got fuel, new battery recently and not been started in 3 years.

When i put the ignition on, it buzzes from engine compartment from icv but no buzz or noise from under the back seat.
When cranking, seems like no fuel going to engine, tried new relays too, and ideas guys? cheers!

Pull out the fuel pump relay, and link together pins 30 and 87 of its base. This should make the fuel pump run continuously, which you should be easily able to hear without the engine running.
If it doesn't run, check fuse 11, but even if this is blown, the fuel pump is likely to be the problem.
If it does run, check for sparks at the plugs, when you crank the engine.
