Car not starting well

[csmitty23]

Just recently I've been having to grind on my car for awhile to get it to start, probably a good five seconds or longer. Once it starts up it seems to run ok, although it does miss occationally. SES light is not on.

I have replaced the fuel filter and the plugs and it hasn't helped.

I have hp tuners and have hooked it up and haven't noticed anything not working right, such as the tps or maf sensor.

What could be the cause, or what tests could I do to find the problem? Thank you.

Do u hear the fuel pump turning on right away?

Re: Car not starting well

Yes I can hear it as soon as I turn the key. I'm worried the fuel pump might be getting weak. Would that cause this problem?

Yes it would. so would a crap battery as well. Get it tested and make sure your connections are good.

Alright. I'm pretty sure the battery is fine, but I have a tester. I'll make sure that's not the problem.

The battery is good. And I got a fuel pressure gauge and it read 50 psi with the ignition on, and 43 at idle, so I don't think the fuel pump is the problem.

However I noticed the IAC valve seemed to make some funny noises. Is there any way to see if it is functioning properly? What else could my problem be?

clean the IAC out with some carb/choke cleaner a few times
