Nissan Platina K class, 2005 model with failures

Hello greetings to all the friends of this valuable forum, I tell you that I have a Nissan Platina K, model 2005, it has given me a lot of can with the coils, in addition a couple of weeks ago a car reaches me in the rear facia, as I only reached the trunk, the same that the insurance paid me and already takes it to repair it; However, a week, the stereo light went down immediately, the gas sensor was turned on and now gives small electric shocks when the key enters to turn it on, also as the battery is going down, they can help me please, I will soon take it to be scanned to diagnose the car since I have few resources, but I would like to have a second opinion of people more experienced that I am on this subject. Mechanica, thank you very much for the contributions you can make.

Look if Check's light does not tell you anything and the problem is only those electric discharges, you do not put a scanner because this will not tell you anything since your problem is electric, it must be a earth problem that does not download or a corrupt that escapes, nothing serious but check it anyway with a sypo electric.

The focus that was turned on to you indicates that there is a leakage of bapor of the fuel tank may be broken with you a line of gases and did not replace or simply with the plug that does not serve well it is enough that that focus is on you. But it is nothing that harms the engine funeral. And from the touches some cable must be giving the land revive all wiring can be dangerous.

You say that you are lowered by the stereo light, it is made to me a cable, I imagine that the current and is contacacoted with something metallic and from there the downloads,
the vapors Czech the tapa of the deposit and look through the rear tire of the right side and check if the duct is not broken. luck.
