Hyundai Help, My Car Not Starting

Randomly went out to the car and it won’t start. The car is working fine, no engine light, new alternator, new battery. AC is turning on and everything, but the car won’t fully start. Does anyone know what this is?

I had this happen the other day; literally everything worked except the car wasn’t turning over until I got a jump, and now it’s been fine since. Fingers crossed.

It’s probably a fuel pump issue. Put your head on the back seat, and if you can hear the fuel pump working, it’s okay. You can remove the seats to hear better.

That’s what I was thinking. It could also be a camshaft sensor; I had the code P0016 come up two months ago, and the engine light randomly went off after that. But the confusing thing is I just had the timing belt and chain and sensors changed in 2023.

Check the fuel pump fuse. It could be the timing belt or the fuel pump. Many factors could be involved.

@MegWhitgal
That’s a cam/crank correlation code. Typically, that’s indicative of a mechanical issue, not just the sensor. It suggests a timing issue within the engine.

It could just be a dead (or low) battery. Get a boost.

Better yet, buy a battery boost box from Amazon and keep it in your car. It’s cheaper than a tow and you won’t have to rely on strangers to help you.

Get a jump and head to a parts store to have your battery and alternator checked.

Go get a new battery.

That engine has no compression. You can tell by the way it sounds. A broken timing chain is most likely. It’s an interference engine, so if the chain is broken, the engine is probably done for.

Would it even start if the chain was broken?

Someone else also mentioned this. But I had the same question: would it start if the chain was broken? Thanks for your response.

@MegWhitgal
Yes, the engine will still turn over, but the top end isn’t moving. The valves won’t open and close if the camshafts aren’t moving. The engine can’t build compression, which is why you hear that free-spinning, fast cranking sound. It’s a distinctive sound if you know what it is. The chain could have also jumped time, causing the top and bottom ends to be out of sync. The valves won’t open and close at the proper time. The 1.8L is, I’m 99% sure, an interference engine. So when timing goes out, the pistons will hit the valves and damage them.

I’m leaning towards the fuel pump. Mine just went out recently. If you felt the RPMs dropping at idle before it happened, that would likely be the cause.

The battery and alternator are new. I tried to get a jump last night, and the car would not jump.

The starter might be corroded. This seems to be common with Hyundai models from 2010-2018.

I had my battery replaced recently, and my mechanic said to keep the battery warranty paperwork. Batteries have been bad lately, and he’s had issues with customers returning with brand new batteries that are dead and can’t hold a charge. He’s switched brands and suppliers multiple times, but the problem persists. They’re just producing garbage.

Hmmm, maybe I should just replace the battery since it’s still under warranty; I just got it two months ago. Thanks.
