In response to Pizzaguy and onehundred80;
Now I know that the links below are not exactly the same as mlister, but earlier in the thread when I first suggested the fuse nine we did not have all the info we do now, and doubt the members in the links below knew the difference between the anti theft alarm module and the Skreem, BUT their cars were not starting and then after pulling fuse nine (some had diagnostic of bad SKREEM modules) they did start their cars and move on. These are only three of several who have had similar experience of pulling fuse nine and getting their cars to start. So do not tell me pulling fuse nine in some, not all, no start situations will not get a Crossfire started. Why this is a solution depends on circumstance ( water in trunk area) but a bad siren can be one of several reasons. I refuse to accept the premise a bad siren can not cause a Crossfire to not start.
There is also a forum member who owns crossfires, makes his living as an auto tech who has experienced a bad siren causing a no start situation; read post six in the SKREEM and PCM link.

Here are just three links to forum members who pulled fuse nine and got their cars stared;
