Ok, I have had a problem with my 91 Camry Automatic 4 cylinder. I am not very good with cars. We replaced the starter on it and it started fine for a couple of days afterwards. The battery tested fine before we got a tune up and replaced the starter. When i try to start it now, all the electrical stuff comes on. It starts sometimes, but it has difficulty and may take about 5-10 seconds. Other times i try to start it, it just clicks one time and doesnt do anything. Any ideas what it could be? Let me know if you need more information?
