Suspected immobiliser/ fuse problem R33

[Kyle1234]

Hey guys, my first post on here. So long story short I own an R33 Skyline Series 1 RB25DE auto from 1993, and its completely stock. I went down to the shops and the car was driving fine, started fine etc.. but when leaving the shops, I did what I normally do by putting the key in the ignition, turning it to the "ON" part, clicking the immobiliser button in, and the dash lights/ radio all lit up as usual for a second or two, and just before i turned the key to start the engine the dash lights/ radio lights just shut off. I had my mechanic whos a family friend come out to look at it, as I suspected it was maybe a flat battery, but we were getting 12.57V to the battery in the boot, we tried to jump start but to no avail. Something else that was odd was to the terminals in the engine bay where you can jump start from also, we were getting no voltage reading, but he said it may have been because the terminals were so dirty. He seemed to think it could be a fuse issue or immobilser but he didn't have the tools to help/ didnt wanna mess with the immobilser or fuses. My cars stranded at the local shops for 48hrs until I can claim service from RAC as I only just signed up for it tonight. Has anyone had a similar issue or maybe could point me in the right direction as to what is wrong with it? Also theres a little red light that will flash 24/7 next to the ignition and when the key first gets put in (without turning at all) theres a beeping sound which I suspect is the alarm, but even that red light wont flash at all. I hope this isn't the end of the road for my car  any help would be greatly appreciated, thanks guys

Didnt make it completely clear, but in short the dash lights wouldn't turn on at all. No crank either when turning key which usually would mean flat battery also. Theres a little green light on the immobilser that will light up when pressing it, and that is lighting up fine, so I guess its not a dead battery in my immobilser?

Doesn't take much power to light that little lcd mate, my remote stopped operating the immobilizer, but was still lighting up. Batteries are cheap. Also check your earth lead.

I dont think it could be the battery in the remote as the little red alarm light next to the ignition isn't flashing either, I think its something more than that, possibly fuse related, but thanks mate

Auto-elec will work out what is wrong with it in about 5 minutes. It will be the ignition switch failed, or something equally dull. Or maybe the shitty immobiliser thing hiding in there. In which case your auto-eleccy will curse your name as he pulls it out because they hate them because they do this sort of shit.

You should just pay for a tow to get it out of the carpark and into a workshop.

This happened to me a few days ago. Was my alarm system had the f**ker removed and getting new system tomorrow happy days.

Another thing before calling an auto elec just pull out fuses one by one if you can't find the English translated panel on the net and look for a busted fuse,  replace with same rating as necessary.

With your alarm system, did you remove that yourself? I found an image on google that as this but im not sure what category the alarm fuse would be under. I might just wait till RAC can help tomorrow night, and if they cant then get an auto elec to come look at it, i would have a go myself but i just dont wanna fk it up more

You're not looking for the fuse that feeds the alarm. You're looking for ANY fuse that might be blown and hence interfering with the car starting.

Any decent alarm installer should never take power from a fused source in the fusebox. They should take power direct from a hot feed and the alarm should have its own fuse.

Yeah as gts said. Stick your head under the steering column you should see some wires with fuses on them, most likely for the alarm, check them out. Other than that I can't help anymore.

I got a mobile auto elec to take it out for me car was completely dead. Should cost no more than $200 for a mobile guy to remove it. I paid  $185 for an hour plus his callout. Anymore than that and they're ripping you a new one.

Hey guys, so after getting the rac to jump start the car and get it back tomy house it was still dead, turns out the metal under the bolts where the earth lead comes up to the battery had been painted over, which caused issues, and my earth cable is actually too small and being strangled a bit so gotta replace that. These older rac guys are so knowledgable its crazy, the young bloke who got my car out of the shops just said it was a dead battery but batterys actually fine in the end. Thanks so much to everyone that replied in this thread it helped me a lot to try and diagnose the issue, and get a better understanding! Legends!!
