   what part of the vehicle was hit in the accident, and how extensive was the visible damage?
Expert:  Steve replied 11 years ago.
 also, do you know what model eagle car it is: summit, summit vista, talon, or vision?  the different models have different components in different locations...
Expert:  Tech501 replied 11 years ago.
 No, you don't have any kind of inertia switch but it is very common for the fuel pump module to become damaged in a collision from the impact. You just need to verify that the power signal is being sent on the feed wire to the pump. Remember, it only powers for 3-5 seconds every time the key is cycled on. If you verify the power signal is being sent, you have to drop the tank and inspect the pump.

Reply to Tech501's Post: HI, THE ANSWER I RECIVED FROM YOU DID NOT HELP.
AS I TOLD YOU. I DO NOT HAVE SIGNAL [POWER] TO THE INJECTORS., & NO POWER REACHING TO FUEL PUMP.I CHECKED OUT PUMP & IT CHECKED OUT OK.
NOT ABLE TO GET IMFORMATION THRU THE SCENNER BECAUSE THERE IS NO POWER TO COMPUTER PLUG.

 I don't have schematics readily available for an Eagle but it sounds like an issue with the ASD relay or it's power sources. If I had a schematic, I could be more specific with it. The ASD relay generally supplies power to the fuel pump relay and the injecters on most Chrysler vehicles.
