so my car wont start cause the battery is dead but if i jump it it will run so i assume that something is draning the battery? idk what tho i checked all the obvious connections and couldnt find the problem. also i have been check engine light problems the code says bad map sensor but ive changed it out like 4 times checked the connection and used someones ecu to find out if that was the problem but it wasnt, so its gotta b wiring rite? any helpful feedback would b appreciated thanks
