This vehicle turns over but does not start. It sounds good while turning over, but does not start.
We were not getting fire thru coil wire, but a check on that showed the wire was good. We had the coil checked and it was good. We replaced the rotor, distributor cap and the pick-up coil. We still are not getting fire thru the coil wire.
The relays like fuel pump, starter relay. auto shut down relay are working. All the fuses are good.
Does anyone have a suggestion on what I can try to check next? We don't have diagnostic equipment other than an ohm meter.

You've already done some of this but we need the rest of the test results to conclude anything.
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.
