ok, i did a little work on my car, took the throttle body and fuel rail off and now when i put them back on my car wont start. the first time i tried it tould turn over but nothing happened so i figured there wasn't enough gas going to it. pushed in the pedal, tried it again, wouldnt even turn over. now when i turn the key it does nothing and all the dash lights go off except the warning lights. (check engine, battery, srs) anybody have any tips that might help? thanks.
