The easiest thing to do is to remove the coil from the motor, and put the tip of a screw driver near the end of it. Crank the motor over and you should see the spark jump from the coil to the screw driver. You can buy various tools that essentially do the same thing, but if you need cheap and easy... Do not hold the screwdriver while doing this... well you can, it's like a rite of passage lol
Unlikely that all 6 coilpacks would fail. What have you tried? Fuel, PTU etc ensure PTU connections are clean.
