I sounds like either a dead battery, maybe dirty battery terminal(s) or possible a worn or defective starter motor. If you have AAA or a friend with jumper cables, try jump starting it. USUALLY, if it clicks and dials start jumping around, The battery is either low on charge, damaged internally, has dirty terminal(s) or the car has a bad starter. When you turn the key, the battery may try to supply 9, 10 or 11 volts initially. This is when your gauges start to go up. As soon as a huge power load like your starter tries to kick in, it draws all of the power away from your gauges and they drop. The battery, for whatever reason, doesn't have the power to run the starter motor, the voltage drops, the starter relay drops out disconnecting the starter. The battery voltage tries to recover and your gauges go back up momentarily until the voltage rises enough to start the cycle all over again. Then your gauges drop and on and on. I have seen this with cars where the battery was run down due to headlights being left on, the battery has died of old age, the starter has an internal short or seized bearing or a defective cell connector has broken internally or something as simple as a dirty or corroded battery terminal clamp or cable where it leads into the clamp..The bottom line is that the starter requires an enormous amount of power from the battery for the few seconds that it takes to start the engine. If the battery isn't up to the task for whatever reason, the starter will demand ALL of it's power. A fully charged 12 volt battery's voltage shouldn't drop below 10 volts during cranking. As the battery ages, the terminals get dirty or if the alternator doesn't charge properly, the voltage begins to drop below 10 volts. If you notice the engine cranks slower and get it repaired soon, no harm done. If you drag every last start out of that dying horse, you can damage the coils inside the starter. A horse will run itself to ***** to please it's master. Electric motors are the same way. If all is well, a starter may draw 150 to 200 amps from the battery depending on several different factors like engine size, cylinder compression and number of accessories belted to it. As the battery ages, it's cranking voltage begins to wain. As the cranking voltage drops below 10 volts, that starter will still try to accomplish the same amount of work to start the engine. You don't get something for nothing. So if you have a high compression V8 with a supercharger, air conditioner, alternator and water pump belted to it, normally it may draw 200 amps to start. At 9 volts, it may draw 250 amps to do the job. At 8 1/2 volts, it may go to 275 amps. These windings in the motor in this example were only designed to draw 200 amps. At 275 amps, it's drawing about 40% more power than they're rated at. If you fix this condition in a day or 2, that small abuse can be overlooked. In a busy delivery vehicle driven until it won't start anymore, it is devastating.
I mentioned the starter being bad as a possibility. If it is the original and well used or if it contains a defective bearing or windings, every time you try to start it, even with a new battery, if the motor doesn't turn, it will act like a wrench dropped across the battery terminals and draw the initial battery voltage way down. When you energize any motor, it converts the energy that you put into it into rotational motion and it runs cool. If you lock that motor so it won't turn like with seized bearings or if the windings inside are shorted, all of that energy has to go somewhere. If the motor is locked, the windings will heat excessively drawing way more power than normal. If the windings are shorted, it will draw even more power due to the fact that it won't have any resistance contained in the windings to dissipate all that energy, again, dragging the battery down. I hope your problem is something as simple as dirty terminals. This would only cost a couple of bucks at most or nothing at all if they can be cleaned. Good luck.

check the linkage arms. most likely fell off the ball socket at the motor

pull relay or switch if goes off test that component if still on test circuit for short

have scanned for location of miss or if multi miss if have been tested good then check injectors /valves and compression test

If you have power to the bulbs then the earth/reversing switch is probably faulty or there is a bad connection in the loom.

If all the lights (hi and lo beams on both sides) are not working) ... then it is probably a relay/fuse issue ... or in some instances it could be the switch on the steering column. If the rear lights go on when you turn the switch on then it is not the switch...so hunt down the fuse/relay box. As I recall on the Type S there is a relay/fuse box inside the hood on the passenger side firewall which has the headlights. Usually there is a map grid printed on the top which tells you which fuse/relay is which. Also take a look at your owners manual...that could help also on location.
Good luck on your troubleshooting

The vehicle speed sensor is located on top of the differential portion of your transmission.

Acura Cars &... | Answered on Nov 15, 2018


this is a easy one three things to check first is oil level ok check wire to oil switch is not broken if all ok it possible could be the oil switch they break down making the oil light to come on good luck but check all I said before you start paying out

Acura Cars &... | Answered on Nov 15, 2018


I their first check the bulb if ok clean the connection if this is ok then it could be the reverse light this is normal found on the gear box but with out checking it could also be on the gear stick good luck any way but check these first

Acura Cars &... | Answered on Nov 15, 2018


Well the first thing you want to do is rule out fuel problems by trying a little bit of starting fluid just a spray and see if it wants to kick off then and if it does then I would say go after the fuel filter first and then the fuel pump second also you should hear a humming when you turn the key into the Run position fuel pump should make some noise you should hear it let me know if you need more help
