Ignition locked up. The car sat for over a year. Ran perfectly until the ignition locked up. No trouble codes or anything. When ignition locked up the wire going to the little light/lamp under the steering wheel like beside the hood release ended up grounding out. Finally replaced the entire ignition switch, lock cylinder and all. Got a locksmith to come out to program the key. I paid him $100. He says he cloned the chip from the original key. Crank no start. My husband is convinced that cloning the original chip won't work for this vehicle. I don't know one way or the other. What I do know is the car still won't start. So, I have it towed to Hyundai so they can program the key. Pay another $120 to have it programmed. Still won't start. So, my husband and I dig in deeper. Even with spraying starter fluid in the throttle body still no start which means it's not firing. We've checked all the fuses. In the small fuse box in the engine compartment (apparently the ICM) there was a 60a fuse that was in pretty rough shape. It was the ACG-S fuse. That's been replaced and still no start. I'm at my wits end with this car. I love the car and have put so much money into it. Too much money into really. It would suck to have to send it to the scrap yard. Any ideas? I could use some fresh ideas here because all I can come up with at this point is using it for target practice.

Yep, we can fix it, if the key is a problem the security light will be flashing so if it is not the security system is disabled. Can I ask if you turn to the on position without cranking the engine over? Can you hear the fuel pump come on for about 5 seconds? Also are there any trouble codes?

This guide can help get the codes:

The ACG-S fuse is not used, see the image below. To confirm the engine has no spark lets go over this guide:

Also, if you can upload a short video of the engine cranking over, I can tell you if the timing chain is okay. Check out the images (below). Let us know how it goes.

No sir, no trouble codes. The security light is solid. Fuel pump is not coming on, but I don't think it's bad because it can be jumped. Give me just a few and I'll post a video.

Can I ask if the engine sounds funny when it cranks over? We can check compression to see if that is a problem in the meantime.

Okay please check the ignition spark because it sounds like the crankshaft angle sensor is not working. Here is the location of the sensor so you can check it out. Check out the images (below). Please let us know what happens.
