Fuses to Check If Your Car Won't Start

Model: (Various brands) Various
Part: Fuse box

Video tutorial

In this video, check which fuses could be essential in the electrical system if your car won't start: the main fuse, which often protects the entire electrical system; if it is blown, the car won't receive power. Also, check the fuel pump fuse, which, if faulty, prevents the engine from receiving petrol, stopping it from starting.

The fuse labelled "ECM" or "ECU", which is for the engine control unit, if broken, halts the electronic management of the engine. The video does not specify the car model, but these fuses are common to most vehicles.

To identify them, refer to the owner's manual of your car, or look for the fuses usually located near the steering wheel or in the engine bay. Once identified, remove them and inspect the internal filament. If they are intact, the issue may be with the alternator or the battery.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
