flat battery?

[redrose]

We put my sons new battery in and same nothing.

code 31 is Theft Deterent signal, which if your keyhead battery is close to flat then wont return a signal to turn the immobilizer off when trying to start, it should still start but with a 1second delay, if the starter motor clicked then keyhead isn't your problem. If the fuel pump didn't prime check the fuse for it in the engine bay.

[redrose]

ok thanks I will check the fuse. the nobby bit on the key is worn I was wondering if this is the problem.

if the keyhead is completely dead then leaving in the ignition at on position for 1hr from memory it should start after that.

my husband just tried to lock the car and the key wouldnt work the central locking he had to lock each door individually. So would that mean it is the key? Thanks for the input.

I had the same problem with my key a couple of weeks ago. Wouldn't work at all, turned out to be the battery. Needed a new one!

[redrose]

Thank you.

Hi i have replaced the key with a new one but still wont go. put new battery in just get clicking in the fuse box in engine bay. the doors wont lock or unlock checked fuses under dash. there was a blown fuse for fuel pump changed that. Help please.

[The1]

if it's clicking near the fuse box it's prob the starter relay, swap it over with say the horn relay and give it another go.

[redrose]

tried that no go. the doors wont even lock or unlock with key. think i might have to get a auto elec to look at it. as there seems no power getting from battery to the car.

checked the fusable links, under the smaller cover in the engine bay.

[redrose]

I checked those and they seem to be fine. i thought it might be the immobiser not going off so will leave key on for 45 min in the morning. i was wondering if it could be the relay that is near the battery i think it has wires going from the battery to it. there are so many things it could be. thank you for replying.

Is the battery ok and charged up?

When you turn the key to on (not start) does the immobiliser light go out?

[turmoil117]

Is it in park? It's probably not the problem but I have done it so many times.

[redrose]

the battery is a new one out of my sons car. the immoliser light goes out when i turn the key on

[redrose]

i have tried to start it in park and neutral but nothing. just the lights on the panel

[tezza]

So the battery is fine, and immobiliser is disarming.

Are all fuses fine? Any clicks heard from the starter motor?

[Jacko84]

does the fuel pump prime when ignition is turned on, does it have spark

[redrose]

Thank you to everyone the car is running ,the earth wire was lose on starter motor and the fuel pump relay fuse was dead. My new key works now. So a big thank you to all and hope you have a great weekend.
