Hook up a fuel gauge to the fuel system. Should be 38-44 psi. If you have pressure then suspect the ignition system. Do the injectors receive a signal from the pcm. Are the spark plugs getting spark? If no fuel pressure then make sure the pump is getting power. Could be bad fuse or relay.
Check distributor rotation to ensure good timing belt. If good, check crank and cam position sensors. The computer fires the plugs and injectors based on many factors but most importantly the crankshaft and camshaft position.
Usually, if you have good spark at all the spark plugs, then, I don't think the coil pack is your problem? If no spark, check primary voltage and ground for the coil pack. There may be an ohms spec for coil, but, I don't have that right in front of me?
If no spark, are you missing anything else? You have good fuel pressure and fuel injector pulse, engine cranking?
I have to ask, how long since a tune-up? Are there any applicable trouble codes?
To check injector pulse, you need 2 people. One is to crank the engine. The other is to watch the voltmeter connecting to the plug delivering the electrical signal to an injector. If during a period of cranking, there is no voltage displayed that means there is no injector pulse. Here is an image of connector port going into the injector to open its valve as needed.
