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 look for.
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 compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Thank you after going thru the list of tests, we found a pinhole in a wire called a fusable link. We examined the piece more and found the wire was broke, repaired it and car runs good. Also there is a second set of 3 relays beside the fuse panel inside the car and the "Ignition Time Delay Relay" got so hot that it actually burned my hand so this was changed.

That could be what burned out the fusible link but it could also be something further down the circuit that is drawing too much current. Time will tell.

We did continue tracing the wire and it is on the same line. Thank-you so much.

That's not what I meant.
I meant that something that operates from that relay may be drawing too much current and causing the overload you found.
