I recently installed an hks supercharger onto my 2018 brz. I used an openflash tablet with a custom tune to tune the car. After installing the base map, I tried starting the car and it would crank but not fire. So I reverted back to the stock map and now the car won't crank at all. I brought the car to a shop and they said told me that the open flash tablet most likely broke one either the bcm or ecm or both. They checked the ecm and were able to load a new tune onto the car with ecutek and checked all sensors but the car still won't crank.
What could be the problem? Does anyone have any solutions I can try before I remove all the mods and bring the car to the dealer? |

No idea what's involved in a supercharger install, but did you verify the simple stuff like there's nothing that would prevent the engine from getting sufficient air, fuel, and spark? Did you change any of those things during the install? I would double-check the easier things before jumping into electronics and tune.
Knowing myself, it would be something dumb like a rag stuffed in a throttle body I forgot to remove. In any case, good luck! Hopefully it's nothing expensive. Sent from my SM-G950U using Tapatalk |

I brought the car to a shop and they told me that nothing appears to be physically wrong with the car. When they use their scan tool, they see all the sensors are okay and providing a reading. They are telling me that the problem is most likely the ecm and bcm. They also said that the ecm was ok since they were able to flash it and that it probably is something wrong with the bcm.

A bad or incorrect MAP sensor shouldn't cause the engine to not crank. Unplug it and try to crank to test this. I second the comment made by @x808drifter about checking the battery voltage and I will also add the recommendation of checking fuses and fusible links. |
