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

 

test your alternator, if its good, replace your battery.
My car was doing the same thing last week, changed battery, runs fine.
moving on now to the next problem
