Fuel Pump Relay Location On 96 00 Hyundia Elantra

Someone will need to check the circuit at the pump to see if it is getting power from the relay. If it is the pump should be running when you first turn the key on.
You can also check for power at the pump relay.

Apparently the relay is not being turned on. I believe that signal would come from the engine computer. Does your check engine light come on when you turn the key to on? If it does, the computer is powered up-if no check engine light, either the bulb has burnt out or the computer has no power-check for a bad fuse.
Put your finger on the fuel pump relay and have someone turn the key to on. Do you feel the relay tick? If you do, check if the relay has one hot wire with key off-use a voltmeter or a testlight. If you do have a hot wire at relay., check fuel pump wiring from relay to the pump. Pull off the connector at the pump and replug it back in.
If you can't find a powered wire at the relay with key off, maybe it is only hot when key is on, so turn key on and check relay again for that power wire going to the relay, one wire should have constant power there. If not, there is a wiring problem between the battery and the relay. If the relay has power to it, but you felt no pulse when turning the key to on, likely the relay is not getting a signal to turn on. A shop would need to investigate that.
Well, good luck, hope you find the problem.

cracked wire or bad pump

Check for burnt fuses or a broken wire. If the relay is accessible check the wires at that point to see if they are carrying power. If so, and the relay is not responding, thne a new relay is in order.

There migh be a loose contact or a wire grounded some where.

there is a relay in the engine compartment relay fuse box should be labeled pull it out look at the relay and jump the same wire the number 30 and 87 on the relay then try and start car. if it don't work check for power there if no power move to the fuse in same compartment.if there is power the installation could be wrong. make sure the ground is properly connected to the frame/body/sending unit.

If there is no power to the fuse block then there has to be a main relay check that to see if it is blown. it is usualy located in the fuse block undr the hood.

check this spot. fuel pump relay is under the bonnet in the fuse box. it should tell you watch one it is
