driver side under dash area makes a constant clicking noise when i push the clutch in, would that be a bad ground or clutch switch faulty, or bad battery. Took the starter to autozone and is passed with good numbers. it used to start before hand, but now i don't now what is causing it exactly.

 

The "click" under the dash will be the starter relay closing when you step on the clutch and opening when you take your foot off the clutch or release key from start position.

The relay may be bad, [contacts] even though you hear it "clicking", if it is a constant clicking when trying to start the car the coil in the relay is bad.

To test, do a bypass jump, using a jumper wire, [12ga min.] from either the batt. pos.(+) post or the batt. cable connection to the starter motor and touch the other end to the starter solenoid control terminal, [the thinner lead terminal you can unplug on the starter motor] BE CAREFULL, make sure car is not in gear, set hand brake, engine will crank even if ign. key is off, clutch is not stepped on and/or car is in gear.

If engine cranks, replace the starter relay. 94

 

alright i tried testing it but the starter solenoid just made a click sound, it didn't turned. So does that mean i have a bad starter? Which is weird because autozone tested it and it passed. So am I missing something.

 

If you do the "bypass jump" and all you get is the click of the solenoid there could be a few things wrong.

It could be a power or grounding issue, to test use a set of jumper cables connected to the batt. posts, clamp the ground to the engine and the pos.(+) to the batt. terminal on the starter motor, then try and start the engine, either with the key or with a bypass jump, if engine cranks/starts it is a connection issue, to see which it is, disconnect the pos.(+) jumper, if engine still cranks you have a grounding problem, check the main grounds, batt. clamp, batt. to chassis ground and chassis to engine ground.
If engine does not crank the problem is a power connection, check the batt. clamp and batt. connection to the starter.

Another possible problem is the batt. terminal, [stud and nut] on the starter motor, the stud itself can be turned when tightening the nut that holds the batt. cable if too much torque is used to tighten the nut, this will misaligne the high current contacts in the solenoid to starter motor connection, you will have to pull the starter to bench test it.
sometimes the contacts can be re-aligned by carefully turning the stud back, [undo] a little, [very little].94

 

It can also be faulty wire as in the terminal that connect from the battery to the whole replay port my father caravan did the same noise but i fixed it due to dirty terminal wire also check relay on starter.

p.s. make sure all wire are has vault going through with circuit tester

 

just making sure there is only two groundings in the engine bay (neg batt terminal to firewall and trans to engine fire wall)right? I also cleaned off the corrosion of the contacts of the wires. so far the car starts now. hopefully it stays like that

 

Sometimes all it is is a bad connection. 94
