[@toddlenard7602]

I know what you mean. We were changing a flat on a big trailer that we were towing and a semi truck come by on the interstate doing about 80 and part of his tire rolled off of the the rim. It looked to me like recap tires. Thank God we were on the other side. It come flying off that semi truck and sliced a metal fender in half all the way to the trailer.

[@laughingone3728]

4:14 .. It's very likely there's a problem with power delivery to the starter. If jump starting works that means an increase in available voltage is able to overcome the issue. That tells me the wiring and connections are suspect, as is the starter itself. It is also possible there could be an issue with the computer needing more voltage to properly actuate the relays and run the starting process. Another likely issue is the grounding/bonding between the engine, body, computer, etc. This is the most common electrical issue in automobiles and is often overlooked. This would also cause power delivery issues like what I mentioned first and second. In short, I would start checking all the major electrical connections on both the ground and power side and consider adding some additional grounding/bonding in appropriate places.

[@MrErichuizer]

Agreed, I was thinking the same thing. Better start checking all grounds etc etc

[@ohsofilthy6877]

[@SadornaGames]

He has push to start, i suspect (as an owner of pts myself) his key battery is dead, and he would need to use the key to physically push the button in, after this if the issue continues then i would start lookkng into issues with the starter, followed by checking the fuses to see if any are blown, if none of that is the cause then its narrowed down to a wiring issue/ground issue. The real question i have is if it maintains power after being jumped and what the alternator was tested at for voltage prior to and after replacement of the alternator and battery. I wonder if they checked all the terminals as well.

[@TommyViper]

[@sometimesleela5947]

Exactly. Whatever the jumper cables are bypassing is the culprit. If they're clamping omto both terminal clamps directly, it's bad/corroded clamps/posts. If they're going to a body ground, it could be the body/frame tie point or the wire. Inspect, clean corrosion, put a high load on like headlights, and use a meter to locate where the voltage is being dropped.

[@HueToobBlows]

Toyo most likely a bad battery terminal or corrosion which is why jumping it works.

[@JasonPrice1]

If jumping that Toyota works, then there still has to be an issue with the battery. You can't be cheap and put in some trash or some random size that "fits". If it isn't an OE or GOOD aftermarket match to OE, they are still doing it wrong.

[@ryantheodore7919]

My dad has some random size battery in his 2018 rav4 because he bought the wrong one. He ended up using a block of wood as a spacer between the battery and the strap. LOL

[@skurblord3401]

It also could be related to the BCM. Many new cars get upset if you don't do stuff with the bcm after a replacement.

[@YourDadBitch]

@@ryantheodore7919 its due to vehicled with certain options having the need for a larger battery. They have the same cranking amps, just wont run the accessories for long without dying. The video, has to be a poor ground connection, or a faulty starter. If you jump you're adding another ground and allowing the vehicle to start. If you jump you're also adding more voltage across the vehicle, which can allow a faulty starter to work.

[@thaddeusmcgrath]

[@ivorgotten2368]

My guess with the non-starting problem: The starter is spinning, but the bendix is not meshing with the flywheel. The bendix spline could be stripped and so could the flywheel teeth. Remove the starter and check the flywheel teeth and the starter bendix teeth, then check the bendix on the bench for proper operation.

[@Fiden6666]

The Jeep had water in the door because of a blocked drain hole, the 10 year (date code 2913) old dry tires are just that and are seeping air through the dry rot, and the Ford won't shut off.

[@101Volts]

Uh, also... Old dried tires *can just lose all of their air rapidly on you,* as in *popping on you while you're driving.* They're a giant safety hazard. I don't have direct experience with it, but close enough: On a trailer that I was allowed to borrow, it had tires that must have been 14 - 16 years old. One of them broke on me, but gradually, 2 miles from home after I was done with all the work I had to do with it. I tried calling who I could, before I drove on a flat; no one answered. I didn't have the spare with me as I wasn't given it, and I had no other option but to drive. I had to limp it home going slower and slower until I was going 5 MPH (if that,) because the rotted tire was just so uneven with no air in it, and the lack of control got worse and worse as I drove. Old rotted tires are like old rubber bands. You *cannot* expect an old cracked rubber band to hold, at least not for long. And it's really best that you don't have a tire go flat on you rapidly. Even if it's just dramatically lower than the right pressure, the car's gonna wander all over the road. And what if you're putting air in it when it explodes? That's not fun at all, and it might injure you or kill you. If it was a Semi Truck Tire exploding next to someone, that's like getting blown up with a grenade.

[@brianboom3105]
