    Hello again forum! I am sad about my ignition. I thought it was probably a weak battery so I replaced it with a really expensive AGM battery, the Odyssey Extreme. I took a video of the situation, which I will try to create a link inside this post. Basically, more and more often, when I turn the ignition key, I hear a slight click like a relay sound somewhere, and the dash lights all go off while I'm holding the key, but nothing happens. I have to turn it a bunch of times and then eventually it fires right up. When it does crank over, it cranks with authority, noticeably cranks harder/faster than it did with the old battery, and fires right up. But it's taking longer and longer to get the truck to start, and this is getting me pretty worried. Sometimes, the engine will actually start cranking and then stop after a few cranks before the engine starts running! This is WITH the brand new fancy battery with 1500 cold-cranking amps!

    There's a lousy electrical connection somewhere. Should I try replacing the ignition switch/module? Is there some electrical connections that I can try cleaning and reseating?

    I'd start by making sure all your battery and ground connections are clean and tight. From what I could tell in your video, looking at the voltmeter it does drop slightly (as it should) when trying to start the truck. If all your cables check out OK then I suspect you have a faulty starter, it doesn't exactly sound too healthy when it finally does crank and start.

    After watching the video, the dash lights go out which leads me to believe it is a worn out ignition switch. There are several contacts in that switch that send power to all the systems in the truck according to the key position, these do get corroded and worn over time. Sounds like you are having to cycle the key several time to get it to start and this has gradually gotten worse so the ignition switch might be an easy solution. Hope that helps.

    Would there be any point in taking out my ignition switch, disassembling it, cleaning and inspecting, maybe rebuilding with parts, or is it truly best policy to just replace it?

    I found some parts on Amazon for a good price. Would you forum members suggest one or both of these parts to fix my problem?

    I have inspected the wires where they connect to the battery terminals last week. There is some corrosion but not too bad I think. I used one of those battery cleaning tools to brush out the inside of the connectors just for a really solid contact, and I have them torqued down properly. The video I took was after that.

    Also I don't know what it is but this truck has always made a huge amount of noise while starting. That whining starter gear noise is probably twice as loud on this truck as on any vehicle I've ever owned, but I figured it was just how these trucks sound. Maybe I'm wrong.... Does anyone else on the forum think these 1st gen Toyota Tundras make an abnormal amount of starter noise while cranking?

    It's a manly strong starting noise not a wimpy starting noise. Enjoy it.

    You certainly can take the switch out clean the contacts with emry paper and give it a shot. Be very careful taking it apart, pay particular attention to how it comes apart so you can reassemble it properly. There are lots of little springs and contacts in there that have to go in a specific way. The easy way is just replace the switch, you can use your old lock cylinder so you don't have to change keys.

    I have mentioned to multiple members of this forum that had this issue, it's the ignition switch. 5 minute repair with parts on Amazon. Two screws on lock cylinder back end. Remove those. Disconnect the ignition cable from switch. Put in new switch aligning it with lock cylinder.
    Voila.
    Good as new.
    I bought my truck with every possible issue you can think of; rust, bad brakes, bad transmission, you name it. Ignition switch was bad and I was dumb, thinking it was the battery terminals. Even if your battery connections were weak, you would still be getting current! You are getting plenty good current from what it sounds like, but the ignition switches contacts are worn, and only conducting current intermittently.
    Hope that helps

    My Tundra has had not had this issue in 280k miles, so I can only speak to other vehicles I have owned that had this issue. One was a starter relay in the fuse box. One was intermittent ground at the starter. And one was a bad switch in the column. YMMV

    Before you go down the ignition switch rabbit hole, the other possibility (the one that happened to me) was the starter contacts were worn out. They are located inside the starter and make contact with each other when the relay sends current to the starter. Over time the area that makes contact can wear out. $13 fix when I did mine. Oh, and $108 for an intake manifold gasket. Not sure how you will be able to determine the cause of your particular problem without trial and error though. Could be the ignition switch....

    I can live with a manly starter noise then. :) I will consider this macho-sounding man-racket from now on. I'd love to add a Magnaflow exhaust to this truck too at some point too.

    Thanks for the tips. I think I will just replace the starter switch after all since we're only talking about $29.

    Just out of curiosity though, if/when I replace the ignition lock cylinder, how does that work since it has to turn with your specific key? Do you take the cylinder to a locksmith and have them redo it inside to work with your key, or do you have to start using a new key that they lock cylinder comes with? Because then I'd have one key for the ignition and another key for the doors.

    You can use the old lock cylinder just remove it from the old switch when you take it out and put it in the new switch. The lock cylinder and the switch are 2 separate parts. You will still use your old key
