Remote start Toyota Sera, Europe

I installed remote start, and the when it starts the engine, you can hear a ticking in the background. After about 5 cycles of starting/stopping, the engine doesnt start, all I get is the ticking. Next time the battery is completely drained, and all I get is a relay click. Any ideas what could be wrong. I'm not using the tach wire, just battery voltage sense, and it's a Boa system, Thanks.

what remote start connections have you made so far..  use the tach its better most timesWhy oh Why didn't i take the blue pill

That problem was due to wiring. Everything's sorted now, but the car will only run for 10 seconds, and in the manual it says that in this case use the tach, but I cant find it! Here's my ECU diagram. Would any of these pins work? http://www.toyotagtturbo.com/wiring/pins1.jpg
