Its been mentioned you need fuel and spark to make fire, but that's not all. You also need proper valvetrain to ignition timing. Did this no-start come out of the blue, meaning it ran fine when parked then didn't want to start the next time? Or, did something strange happen prior, and/or you changed something on the engine?

9434v6:
Being that you own a 3.4, I'd hope you know by now that the 3.4 Camaros and Firebirds don't have MAF sensors. Just throwing that out there.

I didn't read through the whole thread here but it sounds like its flooding. Could be the fuel pressure regulator or possibly a bad vacuum line.

Wait a sec. I never had to mess with one, but how does it not have a MAF? You have the air temp, idle control, and throttle position sensor. does it just delegate fuel depending on the tps then?? I couldve sworn I have seen a mod even for the MAF in a 207.

Nope no MAF sensor. It has a MAP sensor on the intake.

well, i missed a lesson on sensors somewhere. ive heard of map sensors, but never knew any details on them. or that the camaro had a map over a maf. well thats interesting. thanks for pointing that out. learn something new everyday. haha.

that is odd. well i am still learning. i know a lot, but clearly not everything. i hadnt come across an issue with the intake system which is why I never knew. (ive taught myself what i know so far.)

ok you have fuel, now need to check spark quality. weak yellow spark and/or low compression could cause a no fire. gona need to look at compression next. like 69 sayin if valves or pistons are not workin right she wont fire up

Just a caution to mention here for doing this on an ignition that has individual coil packs for each cylinder. I was told the "old fashioned" way may burn out a coil pack so I purchased a test light at Harbor Freight that clips on the plug and then the wire clips onto the tester. I think it was only about $5.00. It also makes it simpler testing spark on any car since it leaves both hands free.
