Hi,
You need to have the cam angle and crankshaft position sensors checked. These are 2 parts which enable the ignition system to fire. If these are ok then check that the rotor in the distributor is turning when you crank the engine.
If it is not turning then you have a cambelt/chain or gear problem which you will need to repair before it will start again.
Hope this helped.
Thanks
Jason

SOURCE: engine died & wont start no spark ignition coil tested good

try your ignition module in the distributor much more likely. just install rebuilt distributor if that is the problem , if you just replace module the main distributor assem will **** out shortly after.
Make sure you check for broken timing belt also it is one of those two!

You are at thhe right trail what controls spark is coil pack crank sensor sparkplugs and plug wire but the most important is power . I mean 12 volt connections and ground This includes checking fuses you need a simple volt meter doesnt have to expensive or fancy just to pick up 12 volts let start with fuses in the engine juction box (there not mark to what it belongs to) make sure none are open. especially fuse 19 and 24 , next go to the crank sensor make sure the tabs are snuggly on now to the coil pack there is a red and light green wire this comes from ignition and feeds 12 volts at the coil pack measure that voltage is it 12 volts if not correct it this is from ignition switch ( you can make a tool that feed 12 volt with a wire and a fuse in series and attatch it to battery and the primary wire this is known as hot wire) next go to the ECM wiggle the wires see if that get a connection going if not go back to the ICM here are the wire you are to measure the tan light green, this is from ECM and it is pulsed it measure 5vlts to 0 volts switched then measure the tan orange the same thing 5 volts to zero,then tan white again 5vlts to zero. any one of these 5 to zero fails you fix is the ecm

Well, first of all, did you fix the problem that caused the fuse to blow? Have you scanned you Antilock Brake System (ABS) module for fault codes? Since the computer is the one responsible for turning the light on, wouldn't you think that the computer would be the one to ask WHY it has turned the light on?
