If the tachometer is moving while you're cranking the engine, that is a good indication that the crank sensor is working. Thats where the tachometer gets its signal. So, for a no start condition you have to start with finding out what's missing. Is it missing spark, or fuel or compression? Those are the basics to a no start condition. These guides will show a lot of things relating to no start issues, but you can try spraying some starting fluid into the intake manifold, this is simulating a fuel source, if the engine tries to start with starting spray, then the engine is lacking a fuel source (i.e., faulty fuel pump, no injector pulse, etc.). The guide will show you how to do these things. You can use a spark tester, which you would plug into the ignition coil instead of the spark plug. The idea is to see what you're missing and go from there.
The first thing you should do to make this real quick and easy on you is on the fifth guide below. (how to test an ignition system) go right to step 22, It shows using a 12volt automotive test light to test for spark out of one of your coils. It's the fastest way to check for spark. After that test, you'll have a direction. If you have spark, then we check for fuel, if no spark, we go after the ignition system. Check a couple coils, go from there. Just keep the test light closer to the coil than your hand so you don't get a shock.
