i'm quite sure he realizes that already, instead of continuing to point out the obvious we could perhaps try to help?

guess so, sad im nowhere close, happy to help

OP, is your Alarm standard OE, or aftermarket?..

If you are not sure PM me your full VIN Number and I can check.

I don't think it is I'm going out here in a few mins to look at the main fuse now
Yes I replaced all the fuses minus the main fuse which I'm going out to do today

Thank you

I didn't have a red top, it was a corroded battery that came with the car so I went and asked for a battery at a shop, they said the yellow top was a good battery and I told them for $225.00 it better be, not really worried about the battery I have gotten that part taken care of but thank you
It's a viper car alarm system

then you also need to find the alarm and check the fuses from it to the fuse box, they will not be with the rest of the car's fuses. most of the time they're simply hacked into the ignition switch under the steering column, and not tied directly to the factory alarm module like they should be.

I go alarm first before anything else then.

BTW: As I said some 2004's had no factory Alarm: Only OE Immobilizer.
If it had a factory system then why would a Viper also be fitted.

Ok. Pulled the main 120a fuse out and it was broken so now I can't find anyone with this fuse , advance auto, autozone, didn't have any at all and now I'm online looking for this fuse and can't find it, I wish I could post a pic on here to show you, I'm going to try and see if this works but none look like this at all, but here goes....
Don't know if they uploaded to this or not

Some more

maybe you will be good then---x fingers for you.

either get one from the dealer or an auto parts store(if not from the dealer bend the flat fingers out and you may have to grind the holes to match).

I saw this one idk if this matters or not

2 Pcs Gold Plated Fuse 120A 120 AMP for Auto Car/Boat/Truck Audio 80x22mm-in Other Electronic Components from Electronic Components & Supplies on Aliexpress.com

If that doesn't solve your problem, then check the Viper module as it will have a starter kill function. So if its not operational and unarmed the car won't start. Or you can simply short out the bypass by reconnecting your starter wire at the ignition, I believe it's purple but I'm not entirely sure.

if I were u I will just remove the Viper alarm.

I would jump 12V to the starter directly to ensure the engine even fires, for that matter.

With electrical problems all the talk in the world is irrelevant, just have to get in their and start eliminating possible causes. One item at a time.

That's what I'm doing now, if this doesn't fix it I will be moving on and replacing all relays

Relays aren't dependent on polarity, fix the alarm first.

You think it could be the alarm? I did the reset on it, the only issues I have now are the doors and windows won't work along with radio, I got power to my headlights wipers blinkers horn dash I don't have power to sun roof mirrors dome lights door lights display radio heat A/C seats

As you have been told the RX-8 main fuse 120 Amp is Mazda part number F151-67-099.

It is also used in ALL RX-8's , ALL NC Miata/MX-5 and Tributes 2000-2003....you may find Ford Explorer of that era also has same main fuse.

M8 you really are not listening to previous comments, in most cases (9 out of 10) like this are after market alarm systems, either poorly installed originally, or they have their own quality/reliability issues..

Repeat what someone else has said, IF you can completely isolate your Viper alarm do so, and then check if engine will fire, windows etc..

Eliminate one thing at a time....

;)

Until you sort out all your fuse/power issues I wouldn't start pointing fingers at the aftermarket alarm system. The immobilizer has several components that all are fed by different fuses and all need power for the car to start. I searched for Immobilizer fuse and found a couple threads, here's one that sounds identical.

If you still have the problem after replacing the main fuse get a multimeter and check for power at the fusebox and check for continuity on each fuse.

When all your accessories have power and the thing still won't start you can rip out the alarm system. Otherwise you just risk disabling the car in a new way by removing the alarm system wrong.

well he actually needs to get the 120A circuit fixed first, that feeds power to virtually the whole car and i can guarantee it won't start with it removed or blown.

mazda probably carries that fuse in stock, a trip to the wreckers would probably also yield something from another vehicle with the same configuration.

but it does boggle me that the huge arcs weren't an indicator of a problem. i've never even blown a main fuse because it's like welding when you try to connect a battery backwards and quite difficult to blow that circuit. i hooked up the battery backwards in my 7 the other day(battery relocated to the bins and can easily fit forward or backward) because i only drive it 2-3 times a year and i still wasn't able to blow the 80amp fuse.

u have a 120amp fuse popped and u not gonna replace that first?

I'm gathering he's figured that out and just needs to find one.

Nothing like a good cliff hanger.

I'm a fatal optimist, except for when I'm not. I hope its just the fuse.
