My girlfriend has a 2006 Chevy Cobalt, a friend of ours thought it would be funny to pull out her fuel pump fuse before she needed to leave for an important meeting at work. After she tried to start her car, it ran for a moment and then shut down. He finally told us what he did, reinstalled the fuse and shut the hood. Now the vehicle only cranks but will not start. I checked to make sure he put it back in the right spot and he did, I listened the for the pump but hear nothing when the key is turned over in the run position. I replaced the relay with identical relays in the fuse box and put the spare 15amp fuse in the fuel pump fuse spot. As she tried to turn the car over i held down the fuel rails schrader valve and got not fuel. Ive tried priming the lines multiple times but turning the key and still nothing. The next day she went out to try and start it, it ran for 45 seconds then shut back off again...and i cannot get it to start now again. I have given all of the information I could provide, does anyone know what may be causing this no start issue?
