Unhappy 98 Camry won't Start after cleaning EGR & Air Intake

I spent the day cleaning the Throttle body and Air intake of my 98 Camry then pulled the EGR Modulator and the EGR Valve. Cleaned them with Carb cleaner and all hoses. This took most of the day due to really trying to clean out the gunk due to a Engine light that said I had an EGR problem - restricted flow.
So I cleaned the IAC, etc with the Camry being cold.
The big problem after getting everything cleanup and reinstalled, making certain the EGR valve was clean and working properly, the Camry not only WON'T start but makes a terrible sound that I have never heard before. I shutter to say that it almost sounds like metal on metal.
The car ran great before I pulled the EGR components off, but was starting to have a problem cold starting. The engine light had been on for a about two months. I had the code checked and found it was the EGR system,but the car ran fine, then cold starting became an issue a few weeks ago, so I assume it was the EGR problem.
I'm hoping that there is just too much Carb cleaner in the system and for some reason is keeping everything from acting normally, so I opened up the air intake and pulled various hoses from the EGR system to let Carb cleaner evaporate,but quite frankly I'm afraid to try and start it tomorrow after what occurred today.
Any help and ideas would be great otherwise I'm stuck until next week.
I know this is a long thread,but I wanted to offer as much info. as possible.
Thanks for any help out there.

You can use this link to check your vacuum lines to make sure they're all connected correctly. If you have the V6 that same web site has that information for that engine.

You may have just flooded the engine with the carb cleaner, especially if you sprayed a lot of it down the throttle body in the process of cleaning. That should evaporate out after sitting awhile.

The metal on metal sound shouldn't be related, unless you got a foreign object through the intake side of the EGR port. I think that would unlikely.

Is there a chance that sound is coming from your starting system?

As for the cold starting problem you were having - those are usually connected with the water temp sensor for the computer (the other is for the temp gauge/idiot light).

Ref: Camry that wont start

Thanks for the info. I'm letting the throttle body and air intake
air out before I try starting it again. I don't think I dropped anything into it. I've been wrenching on cars for about 30+ years,so I try to be careful. I was really surprised by the result of my days work,but I'm hopping that I just flooded it. I had another response from another forum that said the metal to metal sound might be from spraying so much Carb cleaner in that it cleaned the oil from the cylinder walls? I don't think I got that much down there,but the air intake was pretty cruddy,so maybe?

The grinding sounds wouldn't be from a wash off of the oil. If you were hearing cylinder ring noises, that would be a small disaster.

I've been working on cars just as long as a DIY'r, so I know things can happen.

Make sure you didn't drop a wrench, socket, or some other tool down where it could be hitting or rubbing something on the outside of the engine. I've done it more than once...lol.

I know, yer there and can hear the sound, and that may not be it. Just something to check.

You say you had a problem with the car when trying to start it when cold. Explain exactly what you mean by that in all details you can think of.

REf: Camry that wont start

Thanks to everyone who responded. I got it running after cranking is several times and just holding down the starter. No metal to metal sound today and after burning off all of the Cleaner it runs incredibly well. I'm starting to think that the Cleaner was plugging up several valves, hoses etc. last night keeping it from even attempting to start.
Anyway, thanks again! Lesson learned, if you're gonna use lots of Intake Cleaner then either blow out the excess or let it set with hoses off and throttle plate open over night!

Thanks again.

Actually if you are going to do that amount of cleaning you should have removed the intake from the engine. You could have easily hydrolocked the engine and caused severe damage.
