Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

*****I work part-time here on JustAnswer to help you and other repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating.. I will need for you to be my hands and eyes since I'm not there, and to be honest with today's electronics a scantool may very well be needed to retrieve the codes or to monitor data to see what's going on*****

What codes are in the PCM? When it stalls are you loosing spark or fuel psi?

Talk soon,

I need to know what codes are in all the modules.. It sounds like you have a BUS communication issue which could be a module locking up causing the no start.. Let me know which modules are active on the BUS that you can talk to with a scantool...

Lol it quit last night goin to get it but if it helps blue wire with yellow tracer comin from people to asd is prob

Comin from pcm not people
Expert:  Brad replied 1 year ago.

Have you determined which modules are awake and which are dead on the BUS? You will need a scantool to monitor each module to see if it's responding or not. The Blue/Yellow is not working properly because the PCM is likely down on the BUS..
