the dist pickup coil that you suggested didn't work. Any other ideas.

Have 93 ford e150 5.8 was running fine. Then at a stop sign it died as if I had turned the key off. Would not start until It cooled. Then when it reaches operating temp again it dies. Have replaced gas filter, fuel pressure reg, dist module, distributor pickup coil and coil-- -out of ideas. When first started cold it runs fine. also noticed that when it is still idle and close to operating temp, it starts to run rough and if I drop it into gear or tap the accelerator it dies immediately

I will donate if you can help me get this thing running

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.
