2005 Honda Accord Won't Start

I know diagnosing a car problem over the internet may be close to impossible - but I'm wondering if this is a common problem with my type of car, and if so, how can I go about fixing it?

Here's the deal: I have a 2005 Honda Accord EX with about 20k miles on it. I've owned it since aug 08 and it has never given me a problem whatsoever. About a week and a half ago, I parked the car in my driveway b/c I was going on vacation for a week. When I got back home, I found that the car won't start at all. It won't even turn on. I put my key in the ignition and literally nothing happens. There is no clicking from the starter.. No headlights, windshield wipers, etc. NOTHING. The only things that actually work on the car are the brake lights and the horn.

I tried to jump start the battery 3 times with 3 different cars, and to no avail. I don't want to waste money on a new battery if I don't know what the problem really is. I can't even tow the car out of there b/c of the position I have it parked.

I don't know what to do about this -- I know It's going to be very expensive to get a mechanic over to my house. I was wondering if you had ever heard of this problem before?? Please help - I'm desperate.

Try this. jump the car again dont try to start the car right away. let it sit for a few min. when you try starting the car have him give his car some gas. now you car also try shooting some starter fluid to the air in take ( remove the filter ) if the car is try to kick on over.

Honda vehicles may often cause intermittent no-start conditions, especially when the weather gets hot. But the trouble really starts when another component fails, like an ignition coil or an igniter.
Before we diagnose a no-start, let's look at how Honda's main relay works. The relay is a dual relay, that is to say that it is two relays in one. The first relay powers up the computer and supplies power for the second relay. Once the computer is powered up, it will ground the second relay, which supplies power to the fuel pump. There are three conditions that will cause the computer to activate the fuel-pump half of the main relay:
When the key is turned on, the computer will run the fuel pump for two seconds.
When the starter is engaged.
When there is a tach signal to the computer.
Now let's diagnose our no-start. Before I do anything else, I check for a computer reference voltage. This can be done on any input sensor. An easy one to get to is the Throttle Position Sensor. If I have 5 volts there, then I know the computer has power and ground. If the computer isn't powered up, don't even think about trying to trace out fuel or spark problems. There won't be any spark or fuel until the computer has power and ground. Most no-starts are caused by little or no fuel, little or no spark, low compression or spark at the wrong time. These are all easy things to find if a component has failed, but it can be real hard to find a problem that fails intermittently.
Intermittent starting problems are usually spark or fuel. Low compression doesn't come and go. If you had low compression yesterday, you'll have it today. To check for spark and fuel you will need a fuel pressure gauge, a voltmeter and a spark tester. When the engine doesn't start, you want to be able to check the igniter, the coil, the injectors and the fuel pump.
Hook up your fuel pressure gauge. There are two places to hook up a fuel pressure gauge on a Honda. One is on the fuel rail and the other is on one of the bolts on the fuel filter. After you have connected the fuel pressure gauge, start the engine and make sure that there are no leaks. You don't want any leaks while you are testing for spark. Connect the voltmeter positive lead to the ground lead of one of the injectors. Connect the spark tester to one of the spark plug wires.
The most common time to have a no-start condition in a Honda is after a hot soak, like when you pull in for gas or a quick run into a store. The best way to duplicate this condition is to use a piece of wire to hold the throttle linkage and set the engine speed at 2,500 rpm. Let the engine run for about 20 minutes with the hood shut. Then remove the wire and turn the engine off. Let it sit for five to 10 minutes. Then try to restart the engine several times. If the engine doesn't start, turn the key on. The check engine light will come on for two seconds and go out. You should see the fuel pressure go up and hear the fuel pump run during the two seconds. When the light goes out you should hear the main relay click. If it doesn't click, check terminal seven on the main relay (fuel pump) for power and terminal eight (computer) for ground. If you have no power and you have ground, the main relay is bad.
If the main relay is bad on an Accord, you will lose fuel pressure. If it's bad on a Civic, you will lose power to the injectors and the fuel pump but you may not lose fuel pressure because the injectors can't open without power. When the main relay goes bad and there isn't any voltage at the injectors, it will set a code 16 for an injector because the computer doesn't read voltage on the groundside of the injector.
It's also possible that the car has more than one thing that is causing a hard start. You could also have a bad ignition switch, a bad igniter and a bad ignition coil.
If there isn't any spark, move your spark tester to the coil tower to rule out plug wires, cap or rotor. If you still don't have spark, you have a bad ignition coil.
To check the igniter itself, you will need a scope. The igniter terminal of the igniter will have a 10-volt reference voltage. The computer will ground this terminal when it receives a pulse from the permanent magnet sensor in the distributor. The ignition coil produces spark when the igniter releases ground from the negative terminal of the coil. By probing the igniter signal and coil negative you check the input and output of the igniter. If there is a good igniter signal and nothing at the negative side of the coil, the igniter is bad.
The main relay will give you the same symptoms as a bad coil or a bad igniter. A main relay usually only fails when the weather is really hot. You might have a hard start every now and then, but not enough to really cause you any concern, but when an igniter or a coil fails, the car won't start at all until it cools down and that will be a major concern.
NOTE If the car starts and continues to run, the main relay is okay.
Remove the main relay.
Attach the battery positive terminal to the No. 4 terminal and the battery negative terminal to the No. 8 terminal of the main relay. Then check for continuity between the No. 5 terminal and No. 7 terminal of the main relay.
If there is continuity, go on to step 3.
If there is no continuity, replace the relay and retest.
Attach the battery positive terminal to the No. 5 terminal and the battery negative terminal to the No. 2 terminal of the main relay. Then check that there is continuity between the No. 1 terminal and No. 3 terminal of the main relay.
If there is continuity, go on to step 4.
If there is no continuity, replace the relay and retest.
Attach the battery positive terminal to the No. 3 terminal and battery negative terminal to the No. 8 terminal of the main relay. Then check that there is continuity between the No. 5 terminal and No. 7 terminal of the main relay.
If there is continuity, the relay is OK; If the fuel pump still does not work, go to Harness Test.
If there is no continuity, replace the relay and retest.

OR some simple method
check battery (load test) & connections at other end of battery cables for clean & tight.
press the accelerator pedal half down and retry
If it now starts, try running some good injector cleaner through the car
for a couple of fill ups; It could be that an injector is leaking and floods
the engine periodically. Injector cleaner will most likely clear it up

chek these sites

hope your prob will b solved,
do let me kno
all the best

first step CHECK ALL FUSES UNDER THE HOOD AND INSIDE THE VECHICLE.{any blown fuses replace them then try to start} next step go over the work preformed you stated you had the battery and plugs changed, check for the correct spark plugs installed and spark plug gap, MAKE SURE THE SPARK PLUG WIRE'S ARE ON TIGHT AND ON THE RIGHT PLUG(you will feel a click when on tight) sometime's use die electric grease in the spark plug boots to ease them on and this prevent's crrosion,.(IF THE SPARK PLUG WIRE'S WERE NOT INSTALLED ON THE CORRECT CYLINDER(SPARK PLUG) IT WILL MISS FIRE AND MAY CAUSE ENGINE DAMAGE) OR IF YOUR VECHICLE HAS DISTRUBUTOR LESS IGNITION SYSTEM YOU MAY HAVE A BAD COIL/PLUG)now after all that check the battey for correct insalation and positive charge around 12.75 volts is a good charge, after you checked all of the things above and there correct, get in the car, turn the radio off, and put the key in the ingtion get a friend to help have them listen under the rear of the vechicle or in the trunk where the fuel tank is turn the ignition switch on like your going to start it but dont actually start the vechicle, your helper should hear the fuel pump priming short high pitched noise, sometimes you can be quite and hear it inside of the vechicle, if no noise bad fuel pump, if noise your fuel pump is good. and if you have not replaced your fuel filter sience you bought the vechicle now would be a good time.{when you locate the fuel filter usally at the rear left or right of the vechicle frame just befor the fuel tank remove it propley and drain the filter into a clear glass jar and see what comes out rust dirt etc.. do not re install it buy a new one even if it comes out clean. then re try to start vechicle also could be a bad starter its hard to say when i can see or hear the symptoms, there is more i can go into detail but try the easy steps first. hope i helped and not confused you. let me know.

1998 Honda Accord replaced ignition wiring 2 weeks ago had no problems. Now I can't start. It cranks but won't start. No green Key light on dash at all now.

Replace the ignition switch that screws onto the back of the lock cylinder, they were a very common problem and actually subject to a recall. You could phone a nearby honda dealership with your VIN number and they may replace it for free.

2005 Honda Accord will not start, just clicks when turn the key. Tried tapping the starter and rocking the car.

Sometimes if your battery is low there is just enough power to start to close the starter relay but not enough to get past the resistance in the switch. I'm guessing what you hear is the starter relay opening and closing because the battery cannot supply enough power to make it to the starter. My guess would be that you need a new battery or at least a good charge. If you or someone you know has a voltmeter you can check the battery. Just sitting in the car it should be very close to 12 volts. If it is at 10 volts or below it needs to be replaced.
