you should be able to tell by the schematic on the oem relay [if there is
one] - most all aftermarket relays have a diagram. i would just get a
junkyard one - call walt at german auto salvage in berkeley. he'll mail ya
one for 10$. you can clean the contacts and you shoudl be good to go. unless
whoever took it out F'd up the wiring...
i think the fuel pump relay just switches the pump on when the ignition
comes on, i would guess its a spdt 30/40 amp if thats all it does. if the
car runs w/out the relay that likely means that the FP is just 'hardwired'
which may not be so good in an accident. i *think* the FP relay was more of
a safety check than anything.
