The integrated relay IG2 relay outputs +12 to all coils.
In my opinion, the reason is in the specific coil, not in the relay.

 

It's pretty rare for Toyota IG relays and circuit opening type relays to just go bad You would see a whole lot of the car not working at all or you're whole ignition system down things like that You don't have any of that going on so like Max said more than likely it's an individual coil that's fubar causing your mess or whatever is going on these cars now are coming up on the 20-year-old Mark most things have never been done to any of these cars except oil changes and batteries because that's how decent they were now 19 years in you're starting to come up on some of the fun things maybe not fun for you but this is just how it works at least you don't have a brand new Chevrolet one of those terrains or something like that that's got $400,000 things wrong with it before you leave the dealer when it's brand new I guess you don't see a lot of stuff going on on these videos from these garages and places these new cars are great joke I don't even see how I see him driving all around my city.
