so my jimmy wont start without a boost. replaced battery, replaced spark plugs, plugged into the computer and it gave me the code to fix the "TPS" so changed that, the hot/cold sensor..she will start with a boost but without one will just turn without catching. Now its as if the battery is dead-will start again with a boost but once i turn it off, i try to start and its as if the battery is dead. replaced battery again, will start but the next day will stiil only turn over again. i have a tight budget and dont want to keep brining it to mechanics who all have something different to say..every time i think ive figured it out, it still doesnt make sense. any help would be great!!!
