I desperately need help solving this problem..
Ok This is the problem. My car wouldnt start so i thought i needed a new battery but that didnt solve the problem The engine turns alright but it still wouldnt start. So I cleaned the injectors and throttle body and still wouldnt start. I checked the fuel pump fuse and its fine. I pulled out the fuel pump relay and brigde it but didnt hear anything. So with the ignition turned on i went to the trunk and pulled out the fuel pump socket to check to see if there is any power getting to the fuel pump and did not detect any power with my tester. I am at this point stuck and have no idea what to do. Any help would really be appretiated - my car is parked on the street and needs to be moved soon before i get a ticket. Thank you.

fuel pump relay, from there it goes to fuse 18, then it goes to the pump.
Check power first at the relay with your tester, then check power at the fuse then check at the pump last while bridging the relay if everything else checks out ok.
