So ive been working on my instrument cluster and I had the door (light on too) open for 4+ hours and I tried to start it today but I only get a clicking noise. Ive researched a little bit and it seems to be the starter or the starter solenoid, but since I was down in the wires under the steering wheel could I have of maybe disconnected something on accident. Battery is fully charged, I tried to jump the car but nothing either. The car always had a rough time starting so I suspect its the starter or starter solenoid and if it is what brand should I buy or you recommend?

 

test battery

 

make sure the battery terminals are clean.

 

You killed the battery. Charge it up or take it out and have it tested to verify. The "clicking but no start" is a dead giveaway. If that doesn't fix it, as mentioned, make sure all your connections car tight as a poor connection can cause the same issue.

 

If the battery is good it could be a bad ground.
