Ok thank you but when i delete the code the code comming again with no engine light ?

 

perhaps this?

 

There is many sensors so i dont really know which one is it

 

I found that the FSCU is the fuel pump module and is a high failure item. The module then needs to be programmed. If the above link does not work. Look for iScan by Autoland Scientech, they explain everything. Hope this helps. I think they have a youtube channel also.

 

Big thanks to the tstemen . I found that fuelpump has a sensor and that is it
