Try a new relay first. You might have an original 40 year old relay in there. I've had more than one fuel pump problem traced to bad relays.

I'd also check the fuse and rotate it in its holder. That has worked for me several times

Worth it to check the relay and the fuses. I did this for mine, but in the end it was the fuel pump gone dead. My car ended up like this due to the "while I am in there" bug:

Mine did this. Ultimately, had to replace it. (IMG:style_emoticons/default/blink.gif)

I had similar problems. Mine was the relay board itself causing the intermittent problem

Check the relays & fuses first as suggested.
Then check the wiring at the pump to make sure the connections are tight. |
