fuel pressure? spark?

if you have fuel pressure, and no spark, look towards the ignition module. ive replace a hand full of these. however the bad ones ive seen only dropped two cylinders, but im told they usually die completely.

where is the ignition module and how would i need to go about changing it. i have heard that the module could be the problem to but more people said that it probably just jumped time

thanks

The coil pack and ign. mod. are located across from the radiator under the exhaust man. sheild. You can remove the cooling fan or jack the front end up, and go from underneath. There are three bolts holding the unit in, I would detach the three wire molex plugs first. (electrical, two on left, one on right.) After you disconnect the wire harnesses , the plug wires, and the three bolts, (one on the bottom, one on each side towards the top) , it should be free. Becareful! The starter is right near the pack, so if you have the battery hooked up, becareful.
Another thing that might help, take the coil packs and ignition mod. to a reputable mechanic, have them test the coils and the mod. You'll need a 5.5 mm driver to remove the six bolts holding the three coils.
