Was this a pump module that you had to install a provided connector, to allow connection to the new pump module? Open circuit would indicate an empty tank. Referencing the schematic, you could measure the resistance or the sender and circuit from C200, or C405. C200 is at the right of the instrument panel, looks like it may be behind the kickplate, or under the dash. It is a 56 pin connector, with a bolt making the connection secure. C405 is in the rear compartment, forward of the spare tire well. If you get an open circuit reading, you will have to trace it toward the sender. Is this the same function of the gauge, as before you made a repair, or did the malfunction occur after you replaced the pump? Another check that will check the function of the gauge, short pins A and D at the sender connector with a jumper. Like open circuit being empty, short circuit should be full. Turn the key on, and see what the gauge does.
