I have a l200 trojan 07 reg (K74 variant) which has been standing idle for 3wks, I tried to start it today but it wouldn't fire, the battery is in good condition and i checkled that the immobiliser was off. I noticed that the engine management and heater plug lights weren't lit up and the water drain light was on, is there a common reason for this or could it be an immobiliser fault. Anybody had this type of problem?

did it turn over and not fire?

Yes, but not showing lights mentioned thanks.
