I have a 2002 E150 with a 6 cylinder engine. I want to know what the firing order is. Let me paint the picture. If I am in the van with the engine cover off Is plug number the first one on the right? On the coil pack where is the connection for plug one? I just bought the van, and have replaced all plugs, wires, and the coil pack, and it still does not run right. The firing order is the last thing I can think of.
