Hard time starting/cranking car *solved*
Car runs fine.
The car does start up however..
It has a hard time cranking over strong and crisp. Its just a bit weak and it takes a few seconds to start up when cranking.
It wants to start but it just isn't as crisp as it should be.

What is the voltage at the battery?

Pyro made a good point. Sometimes, it will appear that the battery is good, but if you're getting wierd symptoms, then your battery could be going. It has happened to me a coulple of times. Try replacing your battery with a known good one just in case.

10.5 volts during cranking is usually the number I use. If your dropping below this during cranking, you probably have a weak/old battery...Check with a voltmeter actually on the battery itself...
OP- Do you mean the engine seems to crank slower than normal? Im not 100% what you mean by not sounding "crisp".

I don't know if you did this or not but to get a good read of the battery you need to remove the surface charge first. You just run your lights for a min before you measure. A good battery should be 12.6 V or higher and the charging system should be 13.5-15 V.
Cranking voltage should be about 10 V.

If you want more responses, you should follow the troubleshooting procedures that we are advising you to do. It seems like every time we ask you to troubleshoot in a specific way, you shun us as though you don't need to do it.
In my experience, the source of the problem is usually something very simple. I know I have personally done exactly what you are doing now in trying to troubleshoot random problems. We tell you to start with the simplest thing, and work up from there to spend as little money as possible.
Just because the engine was rebuilt 8 months ago or even yesterday does not mean it is in perfect condition and should therefore be eliminated as the culprit.
I'm done trying to help until you post the results of every single troubleshooting step given to you thus far showing that you followed our instructions EXACTLY as perscribed.

So if you had a bad alternator and your driving your car, you are running off the battery ONLY. This would explain slow crank on hot restarts.
After sitting all night, the battery has had a chance to re-coup so to speak. The next morning it seems to start like its got a good strong battery right?
Do you see how a bad alternator could be the issue? If it were me, Id drive on down to autozone or whatever store you have and get it tested. But call first to make sure their in car charging system tester isnt broken.

If it were a bad alternator there would be a point where the car no longer has any current to run or even start. The battery isn't going to charge itself overnight and allow you to start your car over and over without some form of charging system(an alternator).

yup the battery is dropping to much meaning the cells are weak and not retaining much amperage in them man
i was going to ask what fuel your running because e85 is a pain when its cool outside lol

Also check for poor or loose electrical connections at the battery positive post, ground post, chassis ground strap and starter connection. A voltage drop test with a volt meter across any of these connections while cranking will tell you if you have a poor electrical connection. .1 volt across each of connection is about the maximum you want to see. Good luck.

can a dying/weak battery have a toll on any engine components?
can it also rob engine performance? and cause MPG to decrease?

A faulty batter in combination with a bad alternator could certainly be an issue.

re: Hard time starting/cranking car *solved*
battery tested out and it works fine
voltage: 13.02V
measured: 513CCA
rated: 410CCA
Temperature: 20 deg celsius
could a bad/dying starter effect performance?
