On the injector rails, you will find a schrader valve (looks like a tire valve stem). It will probably have a cap on it. After you pressurize the fuel system by switching the key on for 10 or 15 sec., then turning power off, you can use a rag and depress the valve to see if you have fuel under pressure at the rail.
You can use this procedure to see if you have any stored computer codes that may point you in the right direction:
I bought a cheap inline (neon) ignition spark tester at Harbor Freight that I use to visually test if I have spark off the coils (plugs inline with one of the spark plug cables at the coil. Get the wife to crank the engine and eyeball it. Or you can plug a spare spark plug onto the end of one of the cables, ground the metal body of the spark plug and watch for a spark the same way. The tester is much better though and I paid less than $5 for it.
