I own a 2005 chevy cobalt. Recently i hit some debris on the hiway that damaged the fuel pump. and caused a check engine light wich was a short in the vapor emissions circuit. After replacing the pump the car will not start. nor do i have any fuel delivery. I suspect a problem elswhere due to the debris but where?

Damaged wiring to the fuel pump. Gas gauge work ok?
Fuel guage is working no damages to wiring that i can find. Replaced pump relay thinking that may be it. Nothing
Did the car quit running when you ran over debris? At what point or when did the no start condition occur?
It quit when i hit the debris. The fuel pump assembly was shattered ireplaced the entire assembly.
Checked ALL fuses, now that's 'ALL' fuses?
Yes all fuseswere checked.
Well, you obviously have an open circuit to the pump, it is either a bad fuse, relay, wiring, ecm or ecm related. That is all i can tell you. I have a question, how did this "debris" shatter the pump module, considering it's location????

Cked pump with multimeter. Ok. Power across pum solenoid but no power to connector for the plugin for the pump. Pump fuze ok. New solenoid. Now what?
started about 3 months ago, stopped for a while started back, getting worst, replace gas cap and air filter, did not solve problem.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
