Hi Folks, I have a 2006 Aygo with a starting issue. I filled it up with petrol, and when I went to start it there was nothing at the key. The dash lit up with a flashing STOP light, but it wouldn't turn over. The AA moosh checked the battery and that was fine, and we then tried to bump it but nothing. He plugged in his kit and said there were no error codes but he couldn't connect to the immobiliser so he diagnosed a faulty immobiliser. I sourced and fitted a second-hand immobiliser kit (keys, ECU, barrel, transponder, dash/speedo, immobiliser and central locking unit) but it made no difference. I messaged the AA moosh to find out exactly what he found and he sent me this: 'There were no error codes, as there is no communication with the immobiliser control unit. Even the engine control unit didn't have any codes in it. Just a no start signal in the engine control unit when I checked for it in the actual values.' As a note, before the issue, when you turned the key it took a couple of seconds before it turned over and started. I also found a tracking device under the dash - presumably an insurance tracker but I can't see how this would cause an issue. Any ideas? Many thanks, Jason

Hi Oldcodger, Just a heads-up, the issue turn out to be a faulty coil stick. Thanks for your advice, it was very much appreciated! Cheers.

Just an update regarding my '05 Toyota Corolla 1.4 VVT electrical issue and just in case anyone else has the same issue in the future. The IG2 15 amp fuse kept blowing and it turned out to be a faulty coil stick. Cheers.

Thanks again, Oldcodger. I had a rummage around today and found the loom had been hacked about and an extra bank of cigarette-type charger sockets had added and tucked away under the dash with a direct live from the battery. Unfortunately, even after I had removed them, it fault still persists. It looks like I'm going to have to invest in some diagnostic equipment like the Power Probe ECT2000 or something similar.

Many thanks, Oldcodger, The fuse cover on my car is odd as it doesn't reference what the fuses protect, just the fuse ratings. I only got the IG2 fuse idea from a couple of covers I found on eBay from the same model and year car as mine. However, you've given me a few places to start, so many thanks again!

Evening Folks, I have an '05 Toyota Corolla 1.4 VVT that has developed an electrical issue, and I was wondering if someone could offer some advice? The engine was ticking over and then just cut-out and the dash went black. The engine will turn over, but it won't fire. I traced it back to this fuse, but whenever I replace it it blows the second I turn on the ignition. I ran a multimeter to one side of the fuse and I'm getting 12v, but on the other side when I run a continuity test, it suggests a dead short. I believe the fuse be the IG2, but I can't find it on any of the wiring diagrams in the Haynes manual or anywhere on the internet, so I don't know which circuit it protects. Any ideas? Many thanks.

Will do, cheers!
