I have a HSV E3 R8 Clubsport with a LS3. The car, sometimes, will not start. This usually happens when the car has been driven for a little bit then turned off. Then I go to start it again and it won't start. The engine is turning over (so can't be the starter motor) but it won't start. The battery is fine and has the required amount of voltage. Eventually the battery goes flat after a few attempts of trying to start it. After which it gets towed home.
I charge the battery the next day, as it is drained. Once the battery is charged to where it has been all the time (just over 12V) and I attempt to start it again. The first start sounded really rough and it stalled. I try it again for the second time and it fired up as if nothing was wrong. There was a lot of fuel that came out of the exhaust when I fired it up (so I thought that there is nothing wrong with the fuel pump. I thought that was the fuel that was pushed into the exhaust when I tried to start it the first time it broke down). it idles fine and normal around 640-650rpm.
The car has continued to do this for a while now. I can't take the car out because I'm afraid it will break down again but in the middle of nowhere. It still doesn't won't to start sometimes. I start it a few times every day. Some startups are rough, some are normal and sometimes it won't start.
I need help ASAP.
