Video-RX8 GOING CRAZY! turn over w/o key and more, please help
 

VIDEO:


Okay this is not your normal car wont start thread, there is something seriously wrong with my rx8. It flooded a couple weeks ago and I got around to deflooding it last night, and after a short drive I turned it off and went to start it again and this happened..
when I connect the battery, the car turns over by itself for a second!! head lights, brake lights, dash, radio, ect are flashing and stuff and the key is not even in the car at all. I have never seen any car do anything like this. please help. Also it would be nice if you could give me privileges so I could post this in the series 1 trouble shooting forum where it should be, also where more members will see it and hopefully reply, for some reason I doubt this will be an easy fix :(

Anyone?? This thread has 80 views and not a single reply.. please give me permissions so I can post this in the proper forum where members might be more knowledgeable

have you checked all fuses and relays?

This. You have a short somewhere. When you de-flooded, were you messing in your fuse box?

It's that or witchcraft.

It's hard to tell what in the world you are doing with all the cables... but to me the behavior is screaming that you have a severe electrical problem. With everything hooked up properly, the only way that the temporary crank could happen would be if you have a melted relay that is partially connecting, enough to start the cranking briefly before the current load gets too great to maintain the starter and it stops.

The other much more simple way that this all could happen, is if in all of your cable juggling, you once hooked up the positive to negative and negative to positive, sending current backwards through the car, and damaged electronic components. It's hard to do, but possible, with just using the car's battery cables and a battery in the right location. It would be incredibly easy to do juggling jumper cables to a different battery like that.

It wouldn't surprise me if you are looking at very expensive repairs replacing some or all of the electronics in the car.

Yeah sorry the video is shaky, I could have edited it and just showed the weird stuff, but its all there so if you watch the whole video it displays most of the issues.
With the jumper cables I was using a separate fully charged battery that I was also previously using to deflood before I drove it, for some reason when I initially connected the battery trying to film the craziness, I got nothing but this is because this time I had tried it with the key in the on position hoping it would start when the starter goes off, but then I walk back and take the key out and reconnect the battery making sure the ground is good and it got power and I went on to film the problem, that's all.
No I never connected the jumper cables backward, and keep in mind that this problem FIRST happened about 5 minutes after parking the car, with the hood closed and battery connected properly. In fact the first indication that I got that something was wrong is that when I parked it, the fans came on like normal when I turn it off nice and warm, but they shut off after like 5 seconds, previously when they do come on they have stayed on for like 5 minutes.


When I was deflooding, I did remove the fuel pump fuse, air pump relay, and the fuel pump relay but I put that back in to crank it.


I looked at the fuses they are all good, idk about the relays, but like I wrote when I connect the battery they ALL start clicking, with a vengeance.


I completely agree there has to be a short somewhere, and when the load gets great, it shuts it down, the headlights and dash lights coming on could just be a byproduct of this?


or its witchcraft


seriously though this sucks a lot

Relays clicking like crazy with the key on is virtually always a poor battery connection, if everything else is normal.

If you are getting that, or any lights and stuff with the key off and switches off, then you definitely have a really bad short, and are going to need to start looking through wiring diagrams and tracing wires to find it. The short would have to be bypassing one or more switches, like the ignition switch. This is very easily possible with backwards flowing current, very difficult with correctly flowing current.

Your car is possessed. You need an exorcist.

OP, Why?, are you removing both of your cars terminals from car battery and then hooking up a jump start leads from a slave in mid air?

Who the heck told you to do it this way is 'off the air'...

Bolt back your + and - terminals to your fixed to car battery and then use your jumpers from a slave battery (the one on the ground)..with a good connection to car battery.

Then take it from there.

Wow.

BTW: Do you have a wire brush or rough sand paper?, if you have give ALL battery connections a light go over, inside the clamps and around the battery terminal posts, and then connect
both terminals back to battery posts, making sure they are nice and tight, don't over tighten as you could break one, they need to be tight enough so you can not pull them off (upwards)....IF your battery was flat, it needs either a good long drive over an hour or a recharge or a new battery...then take it from there.

Then new Alternator..(make sure drive belt is not slipping and not too tight)

Then auto electrician..

I few questions... it is an automatic or manual transmission? The lights flashing on the dash are to too rhythmic to be a short I would think. The first thought that came to mind watching this is perhaps someone installed a remote starter unit at some point in the cars life. If you are the original owner and you never installed a remote start unit then you will have to start trouble shooting the electrical system. I've a copy of the electrical diagrams for the series 1 RX 8 pm if you need it.
