Reasons for stalling at start-up for a hyundai Ioniq

We are going to build this article with two different paragraphs, one detailing the mechanical problems that can cause your hyundai Ioniq to stall at start-up, then the second the electronic problems.

1: Mechanical origins causing your hyundai Ioniq to stall

We will discover, in this section, the different parts that can cause you to stall at start-up if they were ever damaged.
The idle actuator: Its role is to regulate the air in the engine when it is idling so that it does not choke or stall. If you ever feel that your engine is grazing a little before stalling, it is very likely that this is the cause.
Battery : If your vehicle starts normally and then stalls afterwards, the battery is out of the question. It will only be in question if ever your hyundai Ioniq starts to stall immediately after switching on.
In this case, check carefully on that side.
Also remember to simply consult your dashboard in order to get information about the lights that may be on when your hyundai Ioniq stalls at start-up.
Also, remember to manually check the cleanliness of the parts of your hyundai Ioniq. Indeed, cleaning the parts (filters, injection pump, pressure regulator) could help you. This is regularly the cause of frequent small breakdowns.

2: Electronic origins causing your hyundai Ioniq to stall

We will see here the possible electronic malfunctions which can cause you problems and cause your hyundai Ioniq to stall at start-up, but in general the causes are, as we have mentioned, of mechanical origin.
BSM case: This is the information exchange platform for your hyundai Ioniq. It is unlikely that this is the cause because it is rather reliable. The vast majority of breakdowns related to this box are cars that stall while driving.
BSI box: The BSI unit will centralize information and translate all these different languages ​​for the overall management of vehicle functions. This will sometimes be the cause only if your hyundai Ioniq absolutely does not start.
Calculator: This is the central element of an assortment known as an “on-board system”. The main functionality of an ECU is to provide the correct "weight" of fuel for each stroke of the engine piston. There are various on-board systems that electronically manage the various functions of the vehicle. There are more than 40 on each car! Be careful with this part because some professionals tend to blame this part because they are unable to find the real fault. It would suffice that one of its sensors is defective on your hyundai Ioniq and that the computer is therefore suspected. If possible, consult a second professional if ever you are asked to replace this part because it is expensive.

TDC sensor: Its role is to calculate the rpm on which your hyundai Ioniq is located so that the fuel is sent proportionally. This one could be in poor condition, or simply dirty. Check its condition in order to draw conclusions.
Alternator: Logically, this should be out of the question, because it is thanks to it that the battery starts the car. However, it may be a little damaged and may not be able to recharge the battery, which therefore does not power the car. It therefore manages to light up but goes out just as quickly. This may be the reason for your hyundai Ioniq stalling at start-up.
