I had my starter replaced about a 2 months ago and now my car is having problems starting. It doesnt do it all the time, but is gradually getting worse. It started with 2 cranks to fire and i just thought it was a fluke and today it took 6 times to get it to start. This has only happends after the car has sat for more than 8 hours. What things should i look into before spending money? Thanks for any help.
