I have a 2006 Galnt with a 2.4 liter. I just replaced the engine last week after Walmart it got o add oil to the old motor. This motor has 96xxx. I was driving home from work pulled in to get new wipers the engine light came on and I shut it off. Came out of the store went to start it there was smoke coming out of the hood. I looked under the hood and it cooked 4 ground wires if I had to guess 12 or 14 gauge the bolt to the drivers side fender well under the computer and run up the harness to the drivers side of the engine head. I then discovered the big ground that goes up to the battery had been disconnected. The engine will now crank normally but no start no spark you can hear the humming in the hood of what sounds like a fuel pump. Any help would be appreciated
