Fuel pump and wiring question

I'm currently wiring up my Corolla KE35 with a 4AGE in it, have a question regarding fuel pumps.
On the 4AGE, the fuel pump runs directly off the wiring harness (via the main relay I think - darn it where is the correct wiring diagram when I need it...). However because it's in a previously carby car, I have 2 fuel pumps - 1 facet style low pressure pump and 1 VL high pressure pump. Can I still run both of these off the wiring harness? I've been told fuel pumps don't take a lot of power, but am wondering if I should run these off a relay...
Also, wiring up the chassis and something strange is happening. I've wired in the 12V+ into the main chassis harness, don't have my starter, head/tail light, flasher relays yet so obviously those things don't work yet. Most other things seem to work (stop lights, radio circuit, interior light, clock etc). However, whenever I try to run any motors (heater fan, windscreen wipers, windscreen washer) the motor doesn't run, but instead the dash indicators (not the actual indicators - just the dash ones) turn on. However, if I unplug it completely from the loom and apply 12V to it, it runs. I've looked and looked at the wiring diagram, can't see any reason for this to happen. Even when it's wired up if I turn it on (and it doesn't work, dash indicator turns on instead) and put a volt meter across it, it reads 12V. But the motor isn't running.
Any ideas? Is this because I don't have the relays in yet?
Thanks
