Testing for 12volts to fuel pump must be done while cranking. If no voltage is present then next step is to check all fuses.. Fuses OK? The next tests will require some basic auto electrical knowledge and if you are not sure I suggest taking your car to a shop. Ready? Fuel pump relay is in relay box near battery once located remove and with a known good 12volt test lamp check 12volts at terminal 1 with key on . OK? Check for 12volts at terminal 4 while cranking . OK? Now with test lamp clip attached to positive terminal probe pin 2 while cranking , test lamp should remain on. If all inputs are OK at relay then relay is bad. Apply 12volts to terminal 3 using a fused jumper wire .vehicle should start. Good luck

too old, to post ...? seems not.
check pump voltage at the pump cranking.
then if that fails to be 11v.
then at the fuel pump relay, cranking, (the big pink wire is it)
FI fuses
and ig-coil fuse must be good.
and the CEL lamp glow key on, or ECU may be dead.(ask)
always test with a $10 volt meter,
voltages matter, test lamps were great back in 1950/60.
these cars love to have, like 6 or 8v on the way to the pump, due to rust on the connectors.
the meter shows this truth, and never a lamp.

DITTO ON AUTO ZONE...Don't buy a book, have Auto Zone people copy instructions from their data base for free.

have a budy turn the key on but do not try to start you take the gass cap off and lission to see if you hear a whine or buzz for bout 2 sec try turing the key on and a few times if you hear a buzz then the fuel pump is probabley workinf if not then check fuse and relay first also check timing belt
