Does anybody have any idea what that could be? He claims he's checked the wires and the fuel pump. And just last thursday, he was able to get it running great and then it wouldn't start up on friday. I would really appreciate anyone's suggestions as to what it might be. Thanks..
Can you give us a description of what your mechanic has all checked on the engine or replaced? IT could be a number of different compotents causing a no start. Have the codes been checked, if so what are they??

From the explanation you have given I tend to believe it may be the coil pack, it is a coil pack that has three coils in one, meaning 1 coil of the pack supplies spark to 2 cylinders.

Also if the crankshaft sensor or camshaft sensor are malfunctioning the engine will not start.

Go to the online service manuals posted on this forum and it will give procedures to test coil pack, camshaft and crankshaft sensors.

Keep us posted.
