Well I've more or less given up on the fuel pump thing for now.....I'll keep the hot-switch til I have time to majorly sort the wiring in this car (thinking of adding another relay which would be kinda hokey but would make the pump come on/off when it's supposed to, without the hot-switch).
Anyway, I had the ignition coil disconnected the other day to clean connections. After hooking everything back up (I thought I had it the same) the car ran fine but I had no tach. I had a white wire and a green & black one connected to the negative terminal, everything else to positive. Today I got the tach working by connecting the small white wire to the positive terminal.....! From what I've been reading, and going by the schematic, the tach is supposed to get its signal from the negative terminal, and the other lead for the tach goes to ground. I thought perhaps a previous owner had dorked with the wiring and messed this up, but the terminal on the end of the white wire isn't even big enough to go over the positive post on the coil! So it had to be on the negative post originally, which is how I remember it.
Any ideas what could be going on here?
