My '99 Escort is getting no power

Better to test the pump relay with a meter or a test light. The relay could have failed.
The relay and the fuse should be in the fuse box near the battery.
Check your owners manual for details.

if you have battery power on the large terminal at the starter and the same on the smaller wire when someone Is turning the key to start and the starter has a good ground then the starter is bad drawing too much amperage causing the clicking sound.

The clicking is probably the clue . What ever that relay powers up is draining the battery . This is called a parasitic draw on the electrical system .An there is a way to find the problem . The BEST Way TO Perform Parasitic Draw Test



There should be a tool in the fuse box to pull fuse's with !

I would say there is a short somewhere. You can get a resetable fuse.

Have you checked the fuse or relay? If it gets power and the pump is good, this may be the problem. Thanks for choosing FixYa.

first check the fuse if it is good then check for power at the relay

The headlight relay is located in the engine compartement fuse box.

is there fuel at the fuel rail it may be your fuel pump but that is just a maybe

i can help you with your electrical draw problem though; with the batter charged remove the negative cable at the battery, place a test light between the battery and the negative cable if there is an electical draw the test light should be lit, then go to your fuse box and start removing fuse by fuse until the test light goes off then you know what is drawing electricity most of the times its a stuck door switch that no longer switches the dome lights off or small lights under the dash and stuff like that good luck

Do you have a good 12v source of power when cranking at the starter solenoid wire and is that wire intact and on the right terminal?

Sounds like the auto shut down relay. Located somewhere in the front grille/bumper area. Relay triggers on impact to shut down all power in order to prevent fires etc. Great idea but can cause exactly the frustration you are having if you don't know it's there!!
