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.

That doesn't tell me what your getting right at this minute. You need to know that to get a picture of what's failing. Some systems are tied to mmore than one function.
