Car Starting Problems
Some of the common car starting problems stem from a discharged battery, a bad fuel pump (or no fuel), a weakened starter motor, or a broken electrical connection. Checking each part will help troubleshoot why the car won’t start.

Engine will turn over but will not start have replaced fuel pumpon a 1994 Mazda B4000?
The inertia switch (fuel pump cut-off switch) may need to be reset. Not exactly sure where it is on the 1994 Mazda, but three paces to look are (1) under the mat on the passenger side "hump"; (2) directly behind the glove box; or (3) behind the passenger side kick panel, directly below the glove box. The switch has a button on the top that has to be pushed in to reset.
350 TBI uses an in tank pump to provide about 13 - 15 lbs pressure at the TBI unit. Pour some gas down the throat of the TBI and see if it starts - while it runs for a few seconds, check to see if any amount of fuel spray is coming from the 2 injectors inside the top of the TBI. I had this same problem, but it was the alternator wire from battery to alternator had burn thru, had to repair (solder and Tape) until I could replace this wire. It worked for me. If this working, there will be a continuous fine spray in a cone shape. If not, since the fuel filter has been replaced, you likely have an intank pump that has quit or almost quit. Check that the fuses, wiring etc are OK back to the pump. Next step - remove the tank and remove the pump. You can check it on the bench to see if it will turn over but likely it is toast.
What would cause a 2000 Mercedes Benz ML55 AMG to completely shut down while driving?
I have a 2000 Mercedes ML320 that did the same thing.The problem was the crank positioning sensor once replaced it stopped shutting down
What do you check for if your 1992 Chevy Corsica won't start?
Do computer check, some parts stores will loan you the computer to check your car. Check for spark at he plugs, pull a wire off one of the plugs and have someone start the car, hold the wire close to the plug, one eighth inch, look for a spark, if no spark, do the same thing at the coil, if no spark follow wires back to battery or jump directly from battery, if nothing, pull coil and have it tested at auto supply. If not electric, check for fuel coming from tank, disconnect fuel line and start car, if no fuel it's probably a bad fuel pump.
Replacing a battery in a 1996 Honda passport the Positive and Negative posts unlabled?
I'm not familiar with your vehicle, and I've never seen a battery that did not have the terminal polarity marked.
There are 4 ways [to my knowledge] to determine the polarity of an auto battery's terminals:
1. Most batteries will have a plus symbol [+] embossed [molded/raised] on the plastic of the battery case top panel next to the Positive terminal, AND a Negative [minus] symbol [--] embossed next to the Negative terminal.
2. Or there may be the abbreviation for Positive [ POS] embossed next to the Positive Terminal, and the abbreviation for Negative [NEG] next to the Negative Terminal. Some batteries may have both the symbols AND the POS and NEG abbreviations.
3. On all auto batteries I've worked with, the Positive terminal is SLIGHTLY larger in diameter than the Negative terminal. Thus, the Negative [black] cable clamp should only fit easily onto the Negative terminal, and either NOT FIT on the Positive terminal, or be way to tight to install by hand. And, the Positive cable [red] terminal clamp will fit way too loose [sloppy] if installed on the Negative battery terminal. It should fit "just right" on the Positive terminal.
ONLY use this "trial fit" method with ONE CABLE AT A TIMEuntil you are absolutely certain of which cable fits onto which terminal, because IF you touch both cables to the terminals AT THE SAME TIME, and they are reversed, you will get one hell of an arc [sparking] which could cause the battery to explode, and will probably ruin much of the electronics [computers, etc.] in your vehicle.
4. Another method of determining battery terminal polarity is to use a Volt-Ohm Meter [VOM], with the selector switch set to the DC 50 Volt scale. There are two types of meter: An Analog type [has a needle and voltage scales on the face], and there is a Digital type which uses an LED readout display with numerals to indicate readings.
With either meter, touch the red and black test probe tips to the two battery terminals only momentarily while watchingthe needle, or the digital readout.
IF the Analog meter needle moves to the right, and shows about 12 Volts, then the terminal to which the RED test probe is touched IS the Positive terminal. BUT... IF the needle bounces to the left, then the polarity is reversed, and that means that the BLACK test probe is on the Positive terminal, and the red test probe is on the Negative terminal.
With a Digital meter, the polarity is indicated in the display readout as a plus [+] symbol, or a minus symbol [--]. IF the symbol is +, that indicates that the red test probe is on the Positive terminal and the black test probe is on the Negative terminal. This is as it should be.
IF a minus symbol [--] appears next to the voltage indication, then that means the red test probe is on the Negative terminal, and that the black test probe is on the Positive terminal.
It would be an immense help if you could find a friend or neighbor with some knowledge of electrical polarity to help you this time. Once you get the hang of it , this will be an easy determination. Good luck.
Where is the Starter Sellenoid Located in a 1997 Surburban?
It's right on the starter. The large battery cable and small starter solenoid wire connect there. It's part of the starter assy and not a separate part.
What could be wrong if your car will not crank or start up?
First off, won't start AND won't crank is usually electrical, dead battery, poor connections at the battery or starter, bad starter ( Do you have lights and gauges? ) then that is very much the issue. Do the lights dim when you crank, do they go out altogether, does it start to crank and slowly stop, or does it crank ever so slowly? these are all battery or battery terminal issues, check your battery and clean those terminals to clean metal, check the thick red wire going to the starter, it needs to be mounted well on the starter and not grounding out on metal along the way. Batteries can go bad and still show 12 volts, this happens a lot in winter and summer, extremes in temperature will just kill a battery in a matter of hours so have it load tested.
Where is the starter motor on a Chevrolet Tacuma?
Toyota makes the Tacuma. Chevrolet makes the Tahoe. Which is it?
There is a known issue with Honda Odyssey ignition 1998-99. I think there is an open recall on them. I have a '98 and the ignition started shutting off while I was driving (which is worse than your problem, trust me) and the dealer replaced it for no charge. I would ask a local Honda dealer if the recall applies to your Odyssey. Jeff
You will have to take the ignition key lock out of the steering column, then get a dremel with a small grinder bit. looking at the lock with the key still in you will see two small tabs which come together when the key is in the start position. Take the dremel and grind half off from both tabs as so the key will turn a bit further. sometimes the key doesn't turn far enough to make a complete connection but will still light up. I had the same problem when I replaced the key lock in my 74 Super Beetle and this worked very well. Be careful not to grind off too much or you will have to buy another one. Good Luck
Why is diesel fuel more expensive than regular gasoline?
because of taxes...diesel makes more polution=========
Not true....new low-sulfur and new diesel engines are cleaner and more efficient than gasoline engines.
Factors are higher demand in Europe (more than half the new cars sold in Europe are diesel), distribution (shipping refined diesel from Europe costs more, not to mention the taxes charged by the EU on that refined diesel fuel), less refineries, higher cost of refining (investing in new equipment to produce low-sulfur diesel, although less refining is technically needed), and taxes. Its safe to say 4 out of the 5 are attributed to environmentalists/Liberals.
Check for spark
Check for fuel
While driving what would make the engine cut off and and not restart?
Fuel... either you ran out or the pump stoped working, it could also me that the alternater failed and the battery died.
What could cause starting problems in a Dodge Caravan?
The most common cause of automobile starting problems; is the battery needs to be charged. When the battery will not take a charge. It needs to be replaced.
Car won't start could that be the crank sensor?
It could, but then, it could be a lot of other things as well. Don't replace parts just hoping that you'll solve the problem.
First, run a diagnostic scan. See if the computer knows anything. If that doesn't give you anything valuable, try using a little starting fluid to see if the engine will start briefly that way.
If it has a crank sensor then it must be computer controlled, and the computer knows more about what's going on than you could, just by guessing.
Seriously, don't just throw parts at the problem, since everything you touch introduces the potential that something didn't get put back just right.
If it was running before and now it's not, you typically only have one major problem that caused the failure. Find out what that is before you throw parts at it.
Maybe try the starter or the clyinide. Hope I could help.
When you turn the key the car starts but when you let go of the key it turns off?
It depends on the type of car, but usually it's the keyswitch. Older vehicles sometimes have an ignition resistor that burns out, some have a switch that's part of the starter that can fail.
That really sounds like it is your O2 Sensor. I know for my 94 they are about 22.00 at Advanced Auto Parts. They are on your manifold behind the motor, by the firewall. Have a wire running from them! Hope this helps!

Where is your starter motor in your car?
It depends on the car as it can be located on either side of the engines in different makes. The starter motor can be found lower on the back side of the engine where the engine and transmission meet. The starter needs to engage the flywheel which is where the transmission mounts.
What would be the problem if the starter would keep turning over even when the key is off?
There are a couple possibilities:
If the starter has been replaced and the problem has just begun, check the wiring. It could be that you have crossed the wires to the starter.
If THAT'S not the case, verify that the keyswitch is releasing the starter after you let go. and last, make sure there are no damaged or crossed wires between the keyswitch and the starter.
Why does the Engine turns over slow and wont start when warm?
soundes like your started may be going out or you have a fuel vapor lock problem.
When a car going over 70 mph starts making a humming noise what can it be?
The problem is in the tire balance.Go to your local tire shop and have the tires rebalanced.
answer more that likely is not tire balance tire balance will feel ruff at certain sppeds humming is either tire tread noise on pavement or wind noise but most likely to be tire tread only way to fix is to buy different tires or dont drive at 70 mph,lol
AnswerI don't think it's the tire balance. Humming at higher speeds sounds like a wheel bearing to me. If the sound is less when you're turning one direction, then the opposite wheel bearing is the problem. It's a cheap part and a quick fix; more painless than new tires, which always need to be replaced in pairs at least. Tire problems are way more commonly felt in the steering and suspension, and not really heard.Car will not start on 1990 corolla?
You need to provide more information in order to get an answer to your question. For instance, do the dash lights (check engine, oil, etc.) go on when you turn the key? If not, it could be a battery problem. Do you hear a click when you turn the key? If not, it could be a bad ignition switch or starter. Does the car not start at all, or does it start sometimes? Does it not start on cold starts or hot starts, or both? I've had major starting problems with my 1991 Corolla, so I can sympathize with you. Edit your question by including the specific symptoms and maybe someone will be able to help. Good luck!
