Why does my dl hi relay makes nois when the key is on

Hi Tanner,it's the adjustment screw.

Not enough information.
Is the car completely dead electrically, or does it do things like:
-interior lights operate when door is open
-dash lights operate when key is turned to 'run'
-starter turns when key is turned to 'start'
If you have no electrical power to anything, I would definitely start checking under the hood first. A voltmeter is the tool that will help you the most here.
-Battery terminals tight, battery not dead, cables (both power and ground) carry current where it belongs (zero ohms). Tight electrical connections everywhere.
- The underhood fuse panel contains nearly all the fuses, fusible links, and relays needed for your engine to run. Checking with a voltmeter is quicker than pulling and visually inspecting components.

Low fluid level or loose, worn belt or internal pump parts, bearings worn.

This is usually a sign that the contact points in the Relay are bad and the Relay needs replacement. Another problem can be the wiring to the Relay no longer connects a terminal to the Relay. The Relay would not lock or stay engaged and the Coil inside the Relay would buzz because it can not connect and engage the magnets inside the Relay coil.

need to replace your brakes

Take off the fuse cover and note the location of the in-tank fuel pump & the main pump. If memory serves they are fuses 5 & 7. connect the fuses with a jumper to bypass the pump relay. The fuel pump will come on with the key off! Listen for the sound. No Sound No Pump.
If the pump works, try starting the engine with the jumper attached. If it starts you have a bad relay behind the glove box.

have the transmission mount checked or the cross member bolts to make sur they are tight

a:test the bulbs first
b:test is power to the wire plus to the bulb
c:check the fuse
d:listen where is the low beam relay,usually high beam next of it,change the low relay to high relay see it work.

Sticky relay perhaps, but regardless, have it checked, you really don't want that going off for no reason, and you do want it working properly in case of accident. At least have it properly diagnosed & decide from there.

replace your battery
