Hello, I have some problem with my PCM. When I accidentally cut a oxygen sensor's wire while the car is running, a spark have affect my PCM. Now the fuel pump relay never open and maybe the ignition and injection system. When I remove the pcm to inspect it, I have noted an other metallic box with a lot of connector under the pcm box. What is this box, can it be affected by my oxygen sensor spark?

Thanks a lot for your help !!!

 

That's all I got at the moment!

 

are the first and only owner of the car?

 

no, I'm the second owner, but I have it since three years, why ?
