The ticking noise is the metal cooling.
It sounds like your ignition timing timing is too far advanced. It will need resetting.
most likely your battery is bad if it wont hold a charge unless there is a significant parasitic drain i have no clue on what causes the ticking noise
If your vehicle has a timing belt and not a chain, you need to replace it immediately. My distributor made the same ticking noise and it turned out to be the timing belt had a frayed piece on it and this piece was the source of the noise. Before I could figure it out, the belt broke and left me stranded on the roadside.
Do the light keep ticking or is it just the ticking noise? If it is the noise you can find the ticker behind your stereo. You can buy a new one at any auto parts store. For mine there are alot of different ones, so I pulled the bad one out and took it in with me to match it up. Hope this helps.
Without the year, make or model of your vehicle it could be a bad compressor and or a bad compressor clutch.............
Alternator straining to maintain battery charge?
The question is somewhat vague, not knowing the make, model or year of the vehicle. That said, the most common ticking noise from the bottom of a vehicle is the fuel pump.. It is electric and usually located inside the gas tank.. It does in fact make a constant "ticking" noise when fuel pressure and volume is needed to run the engine. The pump is activated instantly when the ignition key is turned to the on position to build fuel pressure at the injectors for initial start.
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
Take it to a mechanic
if ticking noise is in engine, u most likely have a worn hydraulic lifter. check oil for correct volume and viscocity
yes, my 2000 grand prix gtp is losing power and makes ticking noise.
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
