My 4 Liter Edge cranks but will not start. Been all over YouTube looking for solution and found several things it could be. Short of replacing everything it could be i'm stumped. Problem began just lately when it would start and I would drive to where I was going only to be stranded and have to have it towed. Towed it the last tome to a local garage and they could not get it to malfunction, as a matter if fact they drove it a considerable amount so I picked it up and drove it home now it is sitting. It will run a couple of seconds on starting fluid. I do not get any codes and I have noticed there is no movement on the tach when the starter is cranking the engine. Fuse for the fuel pump has been replaced. I have no idea what to try next.
