My 06 Tiburon was running fine until I stopped, went into a store, then came out about an hour later. I started it up and the CEL lit up. The car began to run really rough and tried to stall. I backed out, sluggishly, and the car struggled to accelerate. After a couple of minutes of this, I parked it to check under the hood. Fluids looked okay. It took about 5 cranks to get it started again and I eventually made it home. Thinking the problem might be electrical, I disconnected the battery and let it sit. I knew any engine codes would be gone, but I figured I could get them back after taking the car out again. Unfortunately, the car has yet to start back up. The fuel pump sounds good and the engine wants to fire, but no luck. I changed the cam and crank sensors and checked the MAF sensor. I found out that I'm not getting any spark. Does all of this point toward a bad ignition coil?
