Does the starter work? Also, are you getting power to the coil?

Starter turns. Low voltage to the fuel pump, works with applied voltage though. No spark to plug. Is the coil under the electronic distributor? I'm old old school and havent worked on cars in a while.
Secondly, how do I check if I'm getting power to the coil?
From what I have gathered, maybe incorrectly, the spread of symptoms. Low (under one volt to the pump), none to the plugs, probably the PCM.
Now, car ran fine, fine then stopped while in traffic one night. Put it in my carport for a while, one month, started it, went in the house, let the battery charge, came out within 5 minutes and it would not start again. The manual "Haynes I have sucks, and I can't find what they suggest. So I've been searching the internet. Just orded a new PCM.

Hi:
I want you to try something. In the relay box under the hood, you will find a relay for the Electronic Engine Control (EEC). Check for other relays with the same part number and switch them out. A bad EEC will shut down power to the pump and the ignition.

Let me know if this works.

I followed your advice and switched the relays and the car started for a few seconds. But the pump is not working on its own. I'm going to go buy a fuel pump relay and see if that will fix it.
Now I know what a fuel pump relay is. I didn't get it in Hayne's. I guess I've been away too long.
I had switched the relays earlier not realizing the consequences and since the fuel pump still didn't work I assumed it was something else. But I guess I made matters worse by putting a bad relay in the EEC.
Now with the new relay I think all is back to normal. I can cancel the PCM on order.
Thanks for the needed education. Now up to 1990's technology.

Is it running now? Also, just remember, engines are still the same. They need to be in time, get fuel, spark, and have compression to run. The only difference (and I agree with you) is they have a ton of sensors and a computer to tell everyting what to do. In a way, it's nice when you can scan the computer and find out what is wrong, but sometimes it sends you on a wild goose chase.

Let me know if it's running now. If not, let me know what is going on. And don't be afraid to get back in touch with us if you have any other questions. I enjoy doing it. It's really a challange via the internet.

The reason I choose to work on the old truck myself is that the last time I took it in to ford they quoted $2000 in repairs. So I replace the Mass Oxygen Sensor myself. Of course it costed me about $100 for their expert analysis. They could be working on commission?
The truck is running fine and I feel less than manly not realizing what I did not know about the term relay. An electromechanical switching device? No. Well yes. But in the fuse box.

Thanks, I'll remember your invaluable help.
