Where is the engine fuse locatio

What now: Please stop guessing and have a professional inspect your vehicle. Or, alternatively, invest in the proper tooling and equipment to perform proper diagnostic tests on your Hyundai, starting with inspecting the fuel system to ensure you have adequate fuel pressure, the ignition system to ensure you have good spark at the engine, and the air intake system to make sure there are no restrictions, and that the air is being properly metered through the intake manifold. You will need a shop manual in some cases, as well as a wiring diagram to do proper circuit testing to see what system has failed and why it has failed. Guessing is quite costly and often unsuccessful...so although I know it may be difficult to handle at times, I strongly recommend a qualified and properly equipped technician have a look at your vehicle. Good luck.
