Hello and welcome to just answerm y name is ***** ***** master tech here to help. I cannot see or hear your vehicle so I rely on your patience and input to my questions so I can help you better. I read your notes and have a question before we proceed. Is the battery original and have you had it load tested? are you trying to start it with that new fob? Did you program that new fob?

Customer: replied 2 months ago.
Answer to your first question is I had the battery charger on to avoid the battery becoming drained when starting it. Answer to your second question is, The key fob was just a shell.. I took the guts out of the old one and placed into the shell with the same key. I then took out the guts from the the shell and attempted to start with same issue cranks but does not turn over.
