I don't know what I was thinking. That car doesn't even have one.
Collisions usually damage the pump internally. If it's getting power and ground to the pump module. Replace the pump.
Look, my original mistake was not paying close enough attention to you question. When I read what you were looking for I immediatly assumed you were looking for the Inertia switch on a Ford since Ford is the ONLY manufacturer that uses any type of external fuel cut off. Only later did I reread your question and realize you were asking about a Crysler product that doesn't even use one. Believe me, I troubleshoot these fuel systems all the time and I assure you there is nothing in the system outside of the pump itself. The only roll over protection in that vehicle is a tennis ball in the filler pipe to prevent spills. Here is the schematic to prove what I'm telling you. The fuel pump circuit is in the lower right of the picture. The pump is what gets damaged in a collision and that's what needs to be replaced if you have no fuel pressure.
