Question about Cars & Trucks
Depending on the make model and year, you may have a distributor or a cam and crank sensor that helps fire the coil. Something has to provide a ground signal to the coil to fire it.
You may need a book to help trace the wiring and test the other components.

cam sensor fires the injectors to synchronise injector pulsing with the spark at the spark plugs.. U need to probably change the crankshaft sensor (around the crank pulley) as the crank sensor is what controls the ignition spark.
hope that does it.

SOURCE: no spark from the coil packs
Check the wiring and make sure your getting 12V to the module (under the coil packs) when the ignition key is turned on. If you have 12V then ohmmeter the coils. The primary side is like .5-1.5 ohms and the secondaries are in the 7500 ohm neighborhood. If all this checks out OK the module would be the culprit.

SOURCE: not getting spark
Testing the coil packs.
1. Get an INSULATED wire and hook it to a ground on the car.
2. Get some one to help you
3. pull a spark plug wire off the coil
4. hold grounded wire close to, but not touching, the part where the spark plug wire connects
5. keep hands away from coil and have your helper turn the engine over ( start car and turn off)
6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced
7. replace the spark plug wire
8. test the rest

The most common reasons for them going out are not using dielectric
grease properly when installing, and from washing your engine.
I believe this was a huge issue with Volkswagen vehicles
