Starting problem is back

[Camry1999]

Hey guys...When I had like 20k miles on the car, it's seemed like like it has really harde to start the car, nothing else, when I went to start it, it cranked over fine, but there was a pause & then it started...after a little while, it went away. Now, I just hit 40k miles & it's doing that again, I thought i was b/c of cold satrting b/c it only does that when you 1st start it up in the morning or when I leave school @ night b/c my car just sits @ school all day. I just hit 40k on it, u think it'll just go away again or is this a sign that something else is worng, maybe I'm getting paranoid but it doesn't feel normal...does anyone know about this...I'm open for opinions, suggestions...

changed your battery lately? weak batteries can often cause a weak starting condition

That's worth a shot...I was going to check the air filter, maybe that's dirty w/all the polution & stuff over here. I do a lot of highway driving...let's see what comes up

Ever changed fuel filters? Slow crank conditions are typically a failing battery (make sure to check the alternator too - if the alternator has dropped a diode or two causing low output, you'll kill a new battery too), or fuel supply issues.

Do a check on CCA on the battery. If it gets too low than it's time to change.
