08 Milan with v6 auto trans

Was running great when it suddenly spit sputtered and died--I checked fuel pressure and looked good so I put a bit of starting fluid down its throat to see if I could get a pulse but nothing---cranks and wont hit a lick.. fixing to go check spark--no codes showing--just fishing for ideas now?

As suspected I have good fuel pressure but NO SPARK at the plug!
Has 60k miles and clean as a whistle---No fault codes--Do I suspect computer as has 6 individual coils---fuse----Ideas? Time to call a real mechanic

OK ---I will just continue this thread solo as time permits in case it will help someone in the future.
My phone calls and research tell me this could very well be a pcm - ecm issue--all coils are not sparking with no codes. I found a few PCMs on nearly identical cars I wouldn't mind taking a chance on but PCM nodel numbers vary slightly so I just don't know squat about them... Still going to check the crank position sensor and go over the fuses again---Frustrating---Car was running great now it is a yard ornament--wife not happy in my old chevy truck---and when she aint happy....well any help appreciated.

Today I am going to change the crank sensor and take off the throttle body so I can get a good look at the three rear coil over packs--I was told to look for melting or some type of heat related issue on them. Then put everything back in and re-test. As a side note I read in the owners manual and confirmed on multiple websites that the pcm (or ecu) is covered under a federal emissions warranty for 8/80. I called dealer and they acted retarded about it so I guess if my efforts today fail to raise a spark I will print the pdf and stick it in their face on tues morning. I will continue to report here as time permits in hopes of helping some other person in the future.

No spark and no codes. Will have it hauled to dealer and expect to have a tussle with them--we will see....

They were great and told me all repairs are covered (someone please wake me up) under 8/80 fed emissions warranty. I will have one more followup post.
