My car has 80000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. Check the throttle position sensor for if its plugged in from when the timing chains were replaced. Also look at the harness and make sure that all of the sensors are plugged in. The idle air control valve (IAC) could be on the fritz. Check the valve and make sure that its functioning. If the valve is not working then I suggest replacing it. If you need further assistance with a no start situation and having to throttle the engine to start it, then seek out a professional, such as one from Your Mechanic, to help you.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won`t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
The 3.6L engine in the applicable model years is subject to timing chain stretch and crankshaft Reluctor ring movement causing trouble codes, engine surging and possibly an engine no start condition. A wide variety of trouble codes may set to include P0008, P009, P016, P017, P018, or P019.
Just like any other misfunctioning component of the engine, a faulty timing chain will illuminate the check engine light. It is a warning to get your vehicle assessed for underlying engine problems, which might include a bad timing chain.
Bad Sensors
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
A malfunctioning timing chain can cause the engine to misfire, run poorly, or even seize up, leading to catastrophic engine failure. As such, it is crucial to ensure that the timing chain is regularly inspected and that any issues are addressed promptly to prevent costly repairs and potential damage to the engine.
The timing chain is a component of the car engine that synchronises the rotation of the crankshaft and camshaft in the engine`s lower and higher portions.
There is a rattling sound. A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
Going too long between oil changes and using the wrong type or viscosity rated motor oil causes the timing chain pins and plates to wear, resulting in timing chain stretch. Timing chain pin and plate wear is accelerated by contaminates in the oil, that is the reason frequent oil changes are required.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
A manifold vacuum and/or barometric pressure, throttle position, engine RPM, coolant temperature, and vehicle speed sensor all modify the timing program.
The MAF can become clogged with excessive carbon build-up from the combustion cycle, or sometimes by road grime. If it is too dirty, it will be unable to correctly measure the air fuel ratio, and cause your car to not start or exhibit other unusual symptoms.
The 3.6 L FCA Pentastar V6 Engine is an overwhelmingly durable and reliable engine. That`s why it`s been used in in more than ten million Chrysler, Dodge, and Jeep vehicles since 2010. With proper maintenance the 3.6L Pentastar engine can provide years of reliable service.
For example, the 2021 Dodge Charger base SXT trim with 3.6L V6 engine (292 horsepower) can reach a top speed of 196 mph and can accelerate from 0 to 60 mph in 6.4 seconds.
Despite its rather lengthy list of problems, the GM 3.6 V6 is known to be quite bulletproof. The v6 power plant is powerful and tech-laden. Its Achilles heel though has to do with its engine oil changes.
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you`ll advance the timing by rotating the distributor counterclockwise, and vice versa.
If the timing belt is broken, it can cause damage to the engine because it will be flailing around and hitting parts close to it such as the valves and the pistons. Replacing the timing chain is a fairly extensive and costly repair because the mechanic will need to talk apart the engine in order to replace the part.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
When your engine cranks but won`t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).

Timing chain positioning
ANSWER : This system is a bit complex. I can give you some instructions, but I highly recommend getting a hold of a repair manual or purchasing a yearly subscription for just your vehicle from AllData. It is only $25 for a years subscription from AllData.
There are two separate sets of marks on this system. One set is for aligning the timing chain to the camshaft gears and the intermediate shaft gear. There will be marks on the chain that raps around the crankshaft gear as well. These marks will not line up after you turn the motor over.The other marks are on the inside of the camshaft gears and align with the cylinder head parting line. If you were to draw a ling through the center of both camshaft gears, they should line up with that imaginary line.
The crankshaft key way should be aligned with the mating face of the main bearing cap. You can confirm it is in the correct position by verifying the number one piston is at top dead center. If you have removed the balance shaft timing chain, these marks really need a visual diagram to understand where they should be aligned. Without a diagram I am not very confident it can be explained very clearly.
This may be difficult to to follow, so again I highly recommend purchasing a repair manual in digital form or a book. If you feel this is over your head, I recommend the following inspection to help you out. Timing chain replacement
Good luck! I hope I was able to help you.

Change my timing chain. Got it on time from upper to lower chain tensioners and now I have no spark.
ANSWER : Hey there. I would recommend checking the camshaft position sensor as this sensor is located near the timing components, to be sure that it is plugged in correctly and working properly. I would also suggest checking the crankshaft position sensor just to be sure it is also plugged in correctly.
As you know, both of these sensors will impact whether or not the motor will produce spark. If either of these are not the problem, you may want to then begin testing the ignition coils for power to be sure they are providing current to the spark plug wires. If you would like to have a professional scope this out for you, a certified technician from YourMechanic can come to your car’s location to inspect the issue getting spark.

Replacing timing chain 2004 Mazda 6
ANSWER : Hello – if the mechanic waited until the car was re-assembled after the water pump job to suggest timing chain repair, then "yes", s/he was not doing you any favor. Doing the timing chain repair separately is essentially repeating the labor. There are a number of related parts involved in a timing chain service: the timing chain itself, one or more timing chain guides, a tensioner, an idler puller(sometimes), and various o-rings and seals. Many parts manufacturers package these as a "kit", and the technician simply orders the correct kit for your engine in order to be sure they get all the right bits. I recommend a timing chain service performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

My mechanic is saying the timing chain is bad (causing oil leaks). Does a timing chain cause oil leaks? What are your thoughts?
ANSWER : Hi, thanks for writing in. Timing change themselves cannot cause an oil leak but the timing chain cover can cause an oil leak. In order to replace the timing cover gasket, you will have to remove the serpentine belt and anything that has belt driven. This includes the alternator power steering pump air conditioning compressor and crankshaft pulley as well as the water pump. Once all of this is remove the timing cover can be removed and the gasket can be replaced. I would strongly recommend having this job performed by a professional as many parts are required to be removed in order to even access the timing cover. Here at YourMechanic, we can have a technician come to your home or office to perform this replacement for you.

My 2010 Chevrolet Equinox has a timing chain replaced and I was wondering if the timing gear was part of this.
ANSWER : Hello. If they replaced the timing chain to begin with then they should have also replace the timing chain gears and the tensioners at the same time. If they did not replace all of these parts when then installed the timing chain then they did not do a good job of repairing the vehicle. If the tensioners continue to fail due to a lack of oil pressure then there are other issues with the engine. It may have a failing oil pump. If you need some help with this engine, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the tensioners keep failing] https://www.yourmechanic.com/services/timing-chain-replacement

if an engine is rebuilt, does that include the timing chain also?
ANSWER : Hi there. Why was the engine rebuild performed? That model year Camry does not have adjustable lifters; they are hydraulic and depend on proper oil pressure to operate properly. These lifters also have to be primed with oil prior to installing during an engine rebuild. There is also the camshaft carrier that has small oil ports to feed the camshafts and lifters with oil. If the technician that performed the rebuild applied too much sealant, one or more of the oil passages could be blocked or restricted resulting in the noise you’re hearing. Then there is also the possibility that the noise could be in the lower part of the engine or an accessory. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts and determine where and what is causing the noise. Your Mechanic has several available technicians that can assist you with an engine is making a noise inspection.

Is the 2009 Sentra 2.0L a timing chain or timing belt? Also when would that need changing?
ANSWER : Hi there. One of the cool things about Nissan four cylinder engines is that they have a timing chain as opposed to a belt. This helps to extend parts life and reduce internal engine failure. The key is to stay on top of routine oil changes and service; including flushing radiator frequently to avoid overheating problems.
