car wont start need help

[2001goldGTP]

i changed my spark plugs, thats it, now the car wont start.I have changed the Crank position sensor, the ICM and the PCM.

So wtf is going on with this thing?

It cranks with no issue, it just has no spark.

Also does anyone have a wiring diagram for the motor?

thanks man, but i meant the wiring diagram for the wires in the wiring harness that lead from the ICM out

ok so you changed plugs and then the car wouldn't start?

 

[2001goldGTP]

yup, when we changed the cam the car wouldnt start for two days then it came to life, and this time its not going to start, same problem no spark, i checked all the fuses too

Did you disconnect the battery? If you did it could be in security mode. If you did't maybe you should... reset the cpus.

battery has been off and one for a long time

How about a bad coil pack? Sometimes you can also forget to connect back the plug going to the coil pack if you needed to make room for yourself to work. I know I had to unplug it for more room. It's in the front on top of the valve cover.

One bad coil pack will still let the engine start.

Does it crank?
Does it sputter?
Did you disconnect anything electrical besides plugs and the battery?

Check your connection at the pcm to ensure it's snug
Check your connection at the icm to ensure it's snug.

My brother had a similar problem like this in his grand am. He would do something minor to it, and the car wouldn't start for a while, than it would magically run fine. Ended up being the cluster in the dash shorting out, and throwing codes everywhere.. Double check your wiring to your plugs, check everything electrical near the area you worked on your car. I'm in a computer class, and my teacher always say's double check everything before you turn it on.

Probably also tells you it worked fine until you let the smoke out.

nope. Never happened to me. I never mess up. I'm a Boss.

I found a regal in the junk yard, I took the icm, coils, wiring harness, I had already replaced my cps. With all regal parts it runs, if I use any of my stock parts it wont. More importantly it runs thanks for the help

Look at the hold harness. Might have rubbed and caused an issue and popped the ICM's mind.
