Start youtubing all of the fuel system testing procedures and get your learn on. Also, as u/avin_2020 suggested, don't forget about the crank angle sensor. A bad one of those prevents the fuel pump relay from activating. So if you turn the key to on and see the fuel pressure gauge read correctly, then start the car and see the pressure fall out

Vehicles that feature a start-stop system are equipped with an electric motor that drives the coolant pump, oil pump, air conditioner, hydraulic pump (if present), and vacuum pump (if present), when the engine is stopped. Changes to the fuel and ignition system are also common on start-stop systems, but that's beyond the scope of this post.

When you come to a stop with a conventional gas engine, it will continue to idle, use up fuel, and produce emissions while you're stationary. Even with a stop-start system, when you take off again

A clicking or tapping sound coming from your engine that gets louder as you crank the engine is most likely “tappet” or upper valvetrain noise, which can be caused by a number of issues including low oil pressure, excessive valve lash, or worn or damaged parts. It could mean a number of things that will not always be easy to diagnose.
The justifications that I have heard are that systems that include start/stop have improved starting efficiency with less energy and gasoline waste, so in comparison the savings over the life of the car mean it is a net positive. Is it true? I have no idea. I still hold to the “the worst part of a drive is the engine start!” thing as well.
2. Excessive Vibrations. Another sign of a failing or bad engine mount is excessive vibrations in the cabin, steering wheel, or floorboard when you come to a stop. This means that the rubber part of the mount isn’t doing its job to absorb the vibrations that are coming from the engine. 3. The stop start functions in cars these days relies on a number of variables. Dependant on engine temp and such. The engines are higher compression for one. The starter motors are high torque and ring gears are wider in some cases. The engine also stops in a specific position to fire up immediately with almost no cranking. So the wear is minimal.

Service Start Stop light on. The light became on and drained the main battery. I had the auxiliary battery replaced and recharged the main battery now I can drive the van. Just the Service Start Stop light is still on. My car is 4 years old and with 32K miles on it.
No, I loathe the damn thing. Especially on an automatic, it doesn't know if I'm stopped for a light or waiting to cross a road. At least on a manual it only shuts off when you release the clutch in neutral. I'll sometimes turn it back on temporarily when waiting at a railroad crossing or something. 38.
Subarus start stop isnt perfect and only turns off the engine in short bursts any extended time or extra strain (ac) will turn it back on. I know on other makes start stop will turn engine off longer than Subarus but theirs did the bare minimum to pass standards. So this car probably still ran a lot. It’s not bad per say but I wish it wasn’t so instant. Like if you stop at a light it immediately turns off but if as soon as you stop the light goes green now you get a delay. Same with a stop sign. If you have to make a quick turn you have that delay of power steering fluid also. Not for everyone but those are things I noticed when driving. Exactly. When I am waiting on stop sign/red light to enter into a bigger crowded road, idle stop is like "hold my beer, you are not entering the road now before that vehicle which is at far distant" and by the time you have released the brake to start the engine, that far distant vehicle is already close enough that you don't want to enter. If you have a good battery and it still refuses to start, then there is a bigger problem down in the crankcase, this is when you should check the fuel pump. A fuel pump is responsible for getting the fuel from the fuel tank to the carburetor or a fuel injector. when the pump fails it makes it hard for the engine to start. 5. Bad Ignition Switch:
To start, tap the side of the carburetor to help the flow of gas. If that doesn’t work, you might have a clogged filter. Not all lawn mowers have a fuel filter, but for the ones that do, it’s usually located in the fuel line or the fuel tank. To find out where the fuel filter is at, check your lawn mower’s owners manual, which will also

If you read the other posters here they did find a solution. I believe it is a bad wiper motor causing a short in the start/stop system. It appears to only happen when there is bad weather (when the wipers are in use). Let me know if you have any more questions we are all here to help! Be strong and firm!! 4. It's louder for a variety of reasons. One is the fact your idle is higher to get the vehicle to warm up, including components, oxygen sensors, and catalyst. Obviously higher idle = more airflow = more noise. The other is that cold components have a looser tolerance until they're up to operating temperature. There's lots more valve and piston Best Loans for Bad Credit; Best Student Loans; but Wefunder's minimums start at $100 while SeedInvest's range from $500 to $10,000 per startup. Keep reading to see how Start Engine works. For more common hills and times, the brake or bite point can be used. I personally will use the latter. For a few second stop, the bite point should be used. This is especially true when the wait is a couple of seconds. This prevents a bunch of shuffle that increases the chance of a stall or bad start-off.

thanks for your input, insightful stuff. I'm not so much of a petrol-head (yet) so I'm getting there. What you say makes sense. With regards to the starter motor, however, from what I read and heard on the MiTo, when it auto-stops the car, the pistons are left in firing order so that when it starts up again the starter motor itself is never involved.
