All "crank, no start" conditions are approached in the same way. Every engine
requires certain functions to be able to run. Some of these functions rely on
specific components to work and some components are part of more than one
function so it is important to see the whole picture to be able to conclude anything
about what may have failed. Also, these functions can ONLY be tested during the
failure. Any other time and they will simply test good because the problem isn't
present at the moment.
If you approach this in any other way, you are merely guessing and that only serves
to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to
These are the basics that need to be tested and will give us the info required to
isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found,
check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found,
check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the
pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
