Could a faulty ignition coil lead to increased emissions?
If it's weak you might have incomplete combustion or possibly an irratic misfire, but most likely the problem that causes increased emissions is elsewhere. An increase in hydrocarbons is often caused by the O2 sensor or possibly the EGR valve. You could also have a problem with plugs, distributor, rotor or plug wires.
Perhaps it's not hooked up correctly? Perhaps there's a bad ground wire? Perhaps your starter relay is out? Perhaps the starter itself is out? Perhaps there's no power to the power distribution center? Perhaps there's a bad wire in the key switch circuit? Without substantially more information, your guess is as good as ours.
I have a cbr 125r have just had a new battery relaced but has already gone flat. Could this be affected by a faulty ignition coil?
What is wrong with my 1994 geo prism Li 6 Cy that has problems starting but after a few tries turning the key and grinding key into ignition it will start?
You could have a faulty fuel pressure regulator or defective ignition switch. You could have a faulty fuel pressure regulator or defective ignition switch. You're not real clear on the starting problem as to whether it won't crank or just takes several tries before it starts. Maybe you just need a tune-up.
you can not adjust emissions there may be a fault if your exhaust is leaking or your oxygen sensor (lambda sensor) is faulty maybe a injector leaking fuel into the cylinder may even be a coil pack or as simple as spark plugs i wouldn't know with out knowing which emissions it is high on i could give you a almost definite answer and explain why i think that if you reply with which emissions…
No fire on 1969 350 engine with hei and accel super coil just replaced with new coil still no fire possible faulty distributer?
On a high energy ignition, possible problems include: Faulty keyswitch, faulty wiring or connectors, faulty pickup inside the distributor, faulty electrical condenser, if it has points (depends on the type of HEI) the points could be bad, faulty coil or faulty HEI control module. You will need to identify which component has failed.
You can crank your 89 crownvictoria from your solenoid but not from your ignition What is the problem?
Assuming that by 'turning over' you mean that it is turning over fast enough to start, this sounds like it could be one of two overall problems; One being a lack of fuel (or possibly too much fuel) getting to the combustion chambers, the other being a fault in the ignition system. With a fuel system problem, possible culprits might be: empty fuel tank (don't just trust your gauge, physically check and make sure by…
Why would a '94 Sunbird randomly have trouble starting after driving over 500 miles without any problems There is no sound or clicking of the starter when ignition key is turned?
My 1988 BMW 735i won't start it doesn't make any noise but all the lights work and the radio and horn works but its not turning over can you help me?
i assume there is no clicking sound??? possible causes could be a faulty igntion switch, try hitting under the steering column where your ignition key goes in, give it some real good hard hits, and try, if it cranks/starts, you have a faulty ignition switch, if not, you may have a blown fuse, a bad battery, or a bad starter, generally speaking, alot of clicking, means a faulty battery, one click, or few clicks means…
Could be a few problems, check the following items. fuel filter cap & rotor (faulty) spark plugs spark plug wires (faulty) ignition module bad (they go on these vehicles moisture problems (get ignition dry and spray inside cap and plug wires (problem with geo's) replace above items and car will run fine, believe me I have been through it.
What makes a 2000 ram with a 360 missfire on certain cylinders very eradicly and it also acts like there is a rev limiter about 4300 rpm?
It could be a lot of things... 1 fuel filter clogged and/or impurities in the fuel system. 2. Faulty or incorrectly gapped spark plugs. 3. Fault in fuel or electrical systems. 4. Bad spark plug wires. 5. Fualty emissions system components. 6. Low compression in cylinders. 7. Weak or faulty ignition system. 8. Vacuum leaks at the throttle body, intake manifold, or vacuum hoses.
Your 1992 Chevy Caprice 5.0 has no spark and will not start what could cause this where should you look?
Why doesnt your 1996 Saturn pick up speed as you merge onto the highway It hesitates even if you floor it It feels like its going to backfire or something but it doesnt actually backfire?
there are alot of components that can cause this action. my first question to you would be, Is the check engine light on? Does it ever come on while accelerating? for diagnostic purposes only, if there is no check engine light, try and get the vehicle scanned anyways. sometimes there are pending codes that will not trigger the check engine light to come on. if you get a code you can diagnose further, and more…
IAC valve faulty or needs cleaning. ( Idle air control valve ). fuel filter could be clogged, wet or damaged ignition wires, emissions or engine control system components are faulty.faulty or incorrectly gapped spark plugs also check the plug wires. vacuum leak at intake manifold or plenum or vacuum hoses. good-day !
