Right so my 99' B4 has developed a electrical problem that has me rather stumped. The car has had the battery run down many times over the years mainly from having the car sitting unused for weeks on end and the alarm draining the battery. Since buying a new forester as a daily, the car sat unused for approx 1 month before being used again. When I went to start the car, unsurprising the battery seemed flat. Attempted to jump start the car which also failed, so I went out and bought a new battery as it was due for replacement anyway. Fitted the new battery and now the car is behaving in a very odd manner. The starter kicks over no worries and the fuel pump primes but the ignition wont catch. Then when I remove the key from the ignition, the CEL light appears very faintly and the radiator fans come on and will stay on unless disconnect one of the terminals on the battery!
Any ideas on where to even start?
