Haven't used the car in a while, but it has been on a trickle charger. Went to start it this morning, both the green lights on the trickle charger are on showing its charged, but the car won't start and it looks like its because of a lack of power. The trickle charger went straight to red after trying to start in a couple of times.

I have turned to ECU on and off etc, nothing.

Any ideas? Don't have another car to use and need to get somehwere pretty quick.
