Ants are unlikely to be the source of your issue. Your battery is filled with sulfuric acid, and that is sufficiently strong enough to completely dissolve any ants that made their way into your battery. Above that, your battery should be completely sealed. Also, even if the ants did manage to get into your engine: metal > ant. This issue is more than likely ...

I recently had a similar problem where I got intermittent "Immobilizer" messages. According to my mechanic (20+ years of Volvo experience) the connector between the antenna ring and the wiring harness sometimes causes problems - taking it off, spraying it with contact cleaner, and re-seating it fixes these. It could be that the vibrations from hitting the ...

Mostly replacement is preventative maintenance. Eventually they'll get cracks that moisture can get into, etc. If they test good, they're probably fine for the moment, however, at their age they could develop problems any time. On my '91 Toyota, I've been through several sets now, and have to say that in my case, OEM is the best. I've tried other brands ...

From personal experience, I'd replaced ALOT of these working at the dealership. It wasn't just the accords either, it was quite a few Honda and Acuras that used the same design and power delivery system. The most common issues I saw out of probably close to 100+ failures of these was: Ground strap on the starter becoming corroded. Bad ground to engine ...

First, think of the possible failure modes: Spark plug is clogged with carbon or has an isolation error - it conducts current, but doesn't generate sparks, because the current flows through the carbon from electrode to electrode. Break inside the plug, e.g. broken / worn electrodes - plug doesn't conduct (and of course doesn't generate sparks) Cable has a ...

Check the other end of the wires to make sure you did not loosen them. Your wires could be going bad and moving them around made the problem worse. Would not hurt to replace them as well. Also it could just be a coincident with the spark plugs, it could be a fuel issue or a problem with your distributor. Although, this is less likely than the first two ...

Most likely cause is a worn or misadjusted clutch. The clutch disc is slipping meaning that all the engines power is not being transmitted to the transmission. Cost of a clutch replacement is to varied to give an accurate estimate. Clarification Note Energy will always take the path of least resistance. From a clutch's perspective, it is much more ...

I'm sorry if this ends up being a lengthy answer. The answer to this question is more historical than anything else but first a little background. In a waste spark system an ignition coil has two spark plug outputs unlike every other system only having one. Each ignition coil is hooked up to two spark plugs. These spark plugs reside in two opposing ...

This is usually the symptom of a dead battery. Has the car been sitting for a long time without being driven? Or did you leave the headlights or interior lights on? Try jump starting it (see owner's manual for instructions) and drive it for a while to charge the battery. (I usually find that 30 minutes or so of driving is sufficient; make sure not to switch ...

Repeated clicking is a result of not enough power making it to the starter. Your battery either has a bad connection, or is too weak to turn the starter motor. Battery Connection Your problem may be entirely due to a bad connection. Starters draw a lot of amps, and batteries are weaker in cold temperatures. I'd start by fully exposing the terminals. You ...

It sounds like your shifter may not be seating into park correctly. You may want to try moving it back and forth from gear into park (occasionally, with a slight amount of force; you don't want to break anything). Verify that the key is not in the accessory position, and each time you switch to park, try to remove the key. I've also seen the key release ...

You have a qualitative description of what happens, but let's break it down to a smaller scale. When we talk about "temperature" of something, we are really talking about how fast the molecules are moving around and bouncing off each other. "Temperature" is really "kinetic energy". And it turns out that there are other types of energy besides moving around ...

Nothing. It could work exactly the same as a keyed ignition, in which case your starter motor would engage, but manufacturers (and I think this is true for all) have added a simple piece of logic which only engages the starter if the engine is not already running. This would be the ideal solution for keyed ignition as well, but it has only been in ...

You need Spark, Fuel, and Compression for an engine to run. Since this engine was just reassembled, there is a lot to question. Spark - rotor position - beware of caps where the points are not "straight through" plug wires in the correct position timing - may need play with it a bit coil - ensure it is firing spark plug firing - use a jumper to connect ...

This could be caused by multiple things, the most likely case would be a bad battery in need of replacement. However before coming to that conclusion there are a few things which can be checked. Make sure your battery terminals are in good working order and are not grounding out any where make sure they are insulated and not cracked and touching metal. ...

Funny you should ask this Max :) First lets make sure of our definition. Running an engine lean means changing the air / fuel ratio to have more air than is ideal (14.7:1 air to fuel). In my reading there are two effects. First, the fuel is an atomized liquid which has a cooling effect on the combustion chamber. So less fuel, less cooling effect. Second, ...

If you are hearing the starter turn (typical starter whir), the most probable problem would be the one way clutch has gone out. It's the part of the starter with the teeth on it which engages the starter ring gear. If the solenoid has gone out, the starter motor will not spin, because the solenoid is the part which forces a large copper washer into the posts ...

A car needs 3 things to start: Fuel, Air, & Spark. You can do try the following to either rule in or rule out the missing piece: To make sure you're getting air and spark, try taking off the mass air flow cover from your manifold, and spray a little starter fluid directly into the intake, while attempting to start the car. If the car is getting a spark, ...

A Good Ground All the coils on that bike want are a good ground. If you can find a good spot on the frame to mount them that isn't in the way you are good. Feel free to weld a couple of tabs onto a random convenient spot anywhere on the good iron from that you can. Best of luck.

Referring to this website: If all is well and there is no slack in the timing chain then you will see about three to five degrees of "reverse motion" before the distributor begins to turn. To measure this, do the following: Get a socket which fits the front balancer crank shaft bolt. Get a breaker bar which is long enough to turn the crank using it. ...

In the dawn of fuel injection most cars used a simultaneous double fire system. During every crank shaft revolution the injectors spray half the fuel needed. This way half the fuel waits on top of the intake valve. When the intake valve opens the first half is dumped in and the injector sprays in the other half the fuel. Similar thing happens with the ...

Pin 16 on the ODB-II connector is specified as "Battery Power" or "Battery Positive". There will always be 12v power between pin 4 and 16. Note that pin 5 has "ground" in the description, but that is just for the communication signalling and not for power. The connector will always have power on these two pins regardless of the key position, and when ...

In the circuit that contains your starter relay there is a fuse, typically it is a 30amp fuse. Here is an image a Yamaha R1 starter relay fuse Depending on your model of motorcycle you will need to: Discover the location of your relay fuse Remove a plastic cover for the relay Possibly, remove a plastic cover for the fuse. Remove and Replace old fuse ...

If you have ever seen an oxy-acetylene torch being used, you will have noticed that before the oxygen is turned on, the torch has a bright yellow flame. This is the fuel burning in a less than ideal amount of oxygen. The flame is relatively cool and it produces a lot of soot. When the oxygen is turned on, tthe flame turns blue and becomes hot enough to ...

If the picture you have attached is similar to the starter on you car, then the power to the starter motor is only delivered if the solenoid operates, so the solenoid must be working. However, the shift lever labelled in the picture, that pushes the pinion forward to engage with the flywheel may be broken, that would explain your problem. Your problem ...

That is probably knocking, or premature detonation. It's a little hard on the motor. It's likely that you should be in a lower gear or ease off the throttle whenever you hear it. It is probably normal for that car. Higher octane gas might help, but it's not good for the car to drive in too high a gear.

Found the culprit the jets were fine, however the float bowl was full of residue and water, as well as the jet carrier bolt being snapped in half so the jets were moving along to where they were not able to fuel the cylinder. After a full strip down, rebuild and calibration its now firing on both cylinders correctly.

Whenever you have a cranks won't run condition the first step is to see what's missing, fuel or fire. First pull a spark plug wire off, stick a thin screwdriver in the end of the wire where the spark plug goes. Hold the side of the screwdriver about 1/4 inch away from a metal part of the engine, while holding onto the handle (insulating yourself from the ...

The words you want to remember while setting the timing is top dead center ready to fire.You want both valves closed.They make a tool that inserts in the spark plug hole that whistles as you rotate the crank to alert you that both valves are closed.Or put your thumb on it and feel the pressure.You want to be TDC on the compression stroke which is 180 degrees ...

If the bike has a carburetor, try cleaning the idle jet (well, just spray the whole intake throat with carburetor cleaner, it's in there somewhere). If it's injected, then run a bottle of fuel system cleaner through it. You might also have a problem with a dirty air filter, but if the bike was just serviced I assume they would have checked that. You could ...
