Ok here is what is going on.

The last two mornings I started my car but it wasnt as smooth as usual. When I turned the ignition the lights went out and then it turned over barely. But the wierd thing is this onlt took place in the morning because after work at around 12 it started fine.

Could it be my starter....i dont think its the alternator..please help me diagnose the issue.

 

Could be the starter maybe starting to sieze (bushes inside worn) BUT i would first of all check your battery condition, in the morning when colder temp the battery will generally have less cranking power and if its duff ie not holding charge this would happen then maybe be okay later once the outside temp has warmed up a little, also good idea to check that the battery terminals are clean and connected tight as if loose will not allow power to get to starter consistently.

If you have a battery tester i would suggest using it and checking the fluid levels in the battery itself. if low this will be the cause of it not holding a charge.

 

How old are your spark plugs? Those are cheap and easy to replace.

Edit: Okay, maybe not, I missed the part about the lights dimming.

 

Unlikely the issue here, as he said the lights went dim and the engine was hard to crank over. Spark plugs would create a hard-start, poor running condition, but would not cause the lights to go dim.

Check the battery and charging system.
