if i remember right the car will run with a bad cam sensor but will not with a bad crank sensor. if your not getting spark and it wont kick with some starting fluid then its not the fuel. not sure on the 3.8 but should be a pink or pink and white wire for ignition juice. make sure your getting juice to the coils. i would look at the crank sensor.

 

Does your crank pulley still have the sheetmetal wheel that goes into the grooves of the crank sensor? If that is gone then the crank sensor will not know it is being triggered. There should be 2 cogged sheetmetal wheels inside the harmonic balancer that trigger the CKS. Those wheels are used for the hi and low resolution crank position readings. The CMS is only used for injector timing and to assist the PCM in adjusting the ignition timing. It will NOT keep you from starting or running. Fuses like Craby said are also a suggestion but if they are not blown...

Just an idea here is your TPS hooked up? GM built a diagnostics routine into these cars where if you press the gas petal to the floor while trying to start the car it will disable the ignition and fuel systems for diagnostics and troubleshooting. Best not to touch the gas petal at all when starting these cars.

Take a look at this, to start diagnosing a no-start condition:

I'm on the same boat as you. I swapped coils and no luck icm is next. Good thing is i get them for free.

 

Love the diagnostics chart Liberty. Good referance for anyone with a crank no start issue. IT also covers many different GM engines too!!

Very informative information, thanks and thanks to all of you guys who have helped! Your all great. I guess I will replace the CKS again... Thats the last thing that isnt new, lol. I had it replaced about 3 months ago, what could have caused it too go out? And... I don't exactly know what I am looking for, can I take a picture and can you let me know how it looks?

 

yes you can. the best way is to open a photobucket accout and download your pictures there, size the pictures at 640 on the big side and you wont have problems posting them on the threads. then copy the img code to your post and the picture should show.

 

The CKS is under the "Crank" right? Here are two pictures at what I'm looking at...

 

i dont have a book for the 3.8 so im sorta in the shade on this one. lol. its under the crank balancer/pulley. massey will respond,,, i hope.

 

Haha, I am almost positive that's it. My problem is that when I turn it with a ratchet, the whole pulley turns. It doesn't get loose, what can I do?

Edit: I think I found out how to do it, I read this guide. http://www.ehow.com/how_6718639_chan...96-camaro.html Let me give that a try.
