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.

1986 thunder bird turbo coupe starts and runs while key is in start position but as soon as its released to on car dies already replaced ignition switch and cylinder its self what could it be?

There is a toothed gear and a rack just behind the keyed switch. Perhaps the gear has jumped a tooth or two. If this has happened take it to someone that can replace both gear and rack. You may be able to "time" the rack and gear that's in there but if it has skipped once, it could happen again. The safe bet is to replace them.

You ran out of gas in 2004 impala now car wont start?

your issue could probabally be a fuel pump. when u run a car out of fuel it runs the fuel pump dry and the only thing lubricating a "in the tank fuel pump" is FUEL

What is wrong when the alternator is charging and the car still looses power and shutoff i then jump start the car it runs but only for a short while then shutdown?

Engine Dies, but Runs for a while After Jump StartingIf you're sure the alternator is working properly, I suspect that you have a loose, or disconnected, connection of the conductor [wire] that is supposed to carry the alternator charging current to the battery, OR a battery that has become defective.

Car wont start just clicks but starts first time when jumped?

Check to make sure the battery cable connections are clean and tight. Have the battery load tested. Test the charging system output. It takes at least 13.5 volts to charge a 12 volt battery.

How do you reset the alarm on a 1996 Nissan infinity Q45?

if you remove the positive over night then put it on in the morning the computer will recalculate over a hundred miles then you can have it checked to see whats wrong

Why wont my 94 Dodge colt 1.5L wont start got spark fuel to all the injectors sucking air timings bang on?

My colt would fire then die often. Run occasionally for a few minutes, then die. Ater replacing or cleaning everything. I found the MAP sensor was bad. Napa is the only parts store that has it. If you do a search for it on their web site you will see a picture of it.

Why Wont my Dakota start if wet or muggy outside?

the coil or the distributor cap has a crack in it, try spraying wd40 on them

When you turned the key in your car to start it you heard a clicking sound What could that be?

There are a few possibilities: Low battery, either because the alternator isn't keeping the battery charged or the battery is old and has failed. Corroded battery terminals, usually an indicator that the battery is blowing acid fumes. Batteries usually don't last long after the terminals start to corrode. Faulty starter solenoid. IT SOUNDS LIKE IT COULD BE YOUR STARTED CYLINOID

Why wont your 1997 Kia Sportage start if it turns over have spark have fuel?

replace both the main relay and fuel relay , they interact with each other. So if one is acting up it affects the other one. They cost $ 16.00 each from Kia. More than likely that is your problem. If your timing belt is good.

Why is there no power to the ignition switch?

normally a fuse but the switch needs to be connected to something i.e car, bike, monster truck etc

Where is the fuel pump located on a 2000 Saturn LS?

INSIDE the fuel tank. You have to drop the tank to get to the pump.

What causes orange spark In a car?

That depends;

on an older car I'd suggest that it's probably the condenser, but if it has an electronic ignition I'd also check the ECM and coil.

Infinite Starter location infinite starter placement Where is the starter on my infinite G20?

The starter should be located behind the engine on the driver side next to the Bell Housing for the transmission. The starter should be located behind the engine on the driver side next to the Bell Housing for the transmission.

1990 300zx The car will not start unless you run a wire from the ignition to the starter. Could the security alarm be affecting it.There isn't a relay in the alarm system?

There is a relay between your ignition switch and the starter though. Check in the driver's side fender well above the fender skirting. You will find an inline relay.

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.

You Have a 1989 Suburban with 5.7l TBI you are unable to start When attempting to start you hold gas peddle down and it trys to roll over with smoke emitting you have replaced the inline filter?

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?

Automotive Battery Terminal Polarity Identification
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.
