You need to first test a few functions during the failure.

1) Test for spark at the plug end of the wire using a spark tester.
2) Test for injecter pulse using a small bulb called a noid light.
3) Use a fuel pressure gauge to test for correct fuel pressure.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
Here's what the noid light looks like.

Answer

You plug it into any one of the injecter plugs and crank the engine, if it flashes, all the signals are arriving at the injecter. If it doesn't, make sure you have power supply at one side of the injecter with the key one. That will only leave the computer ground signal that is missing.
