Elantra HD (2006-10) :: 2009 - Intermittent Start / No Spark
Feb 17, 2015
One morning my 09' Elantra didn't start. It sounded like it was only the starter running. I checked the spark and there wasn't any. I checked the fuel injector pulse and got nothing. Occasionally I could get it to start just by trying a bunch of times but never more then once in a row (or day for that matter).
I decided to replace the Crankshaft Positioning Sensor. The first time it took a bit but started up and ran nicely, till i turned it off. Now I'm back to a no start car and again with no spark or fuel injector pulse. It does feel like it's trying to turn over just a little bit now that i replaced the sensor.

I bought a 2010 Elantra touring last September (it now has 166000 km). I love the car except for the hard shifts. It happens every morning when moving from a cold start. They vary from slight to pretty noticeable. I had the transmission flushed shortly I got the car. I just had the transmission reset about 2 weeks ago. It was smooth as glass for about a day or so after. Then back to square one. Yesterday it hesitated shifting between 4th and 5th going back and fourth a couple of times.

I have a 2009 Entrant, lately I've started experiencing no crank starts, I try a couple of times and then it starts normally. The car has new battery and terminals so am thinking it might the starter. I've looked online on a how to change starter for a 2009 starter video but no dice. I've found every other Hyundai but not the 2007 to 2010.

So the situation is my battery died on my car and whenever I go to jump it the alarm goes off as soon as the cables connect. I let it sit for a minute and the alarm goes off for a period then turns off, then it starts going off again then turns off repeating this. The car wont turn over and I can't figure out how to turn off the alarm. How to get it to jump/turn off the alarm while it charges? I wont take it to the dealer to get it fixed unless its 100% something I can't do at home.

Love the car, but in the last 2-3 three weeks it just randomly refuses to start. Turns over fine but seems like its not getting fuel. It is most likely a relay that needs replacing. This relay apparently controls the computer and the fuel pump. Maybe I'm just looking in the wrong place. I hardly dare drive my car anywhere now for fear It will not start when time to go home.
In the meantime, I seem to be able to get the faulty relay to function (if that really is the problem here), by making sure lights and radio are turned off, and by turning ignition key just one click (listening to be sure fuel pump has loaded the lines) before actually starting the car. No point in running battery low cranking engine over and over, waiting for that magic moment when the car suddenly starts like there was never any problem at all.

I have a '97 Hyundai Elantra (That has been turned in to a Dirt Race Car) anyway the car will idol for an hour fine. When we take it on the track it will run 4 or 5 laps fine then we take it in the pits shut it off for an hour and then go back on the track and on the 2nd lap it will quit and will not start it will crank but their in no spark also the dash lights no longer work. After the cars sits for a couple hours it will start back up and idol fine. We have replaced the ECU/ECM relay as we thought that was the problem but the symptoms remain the same. We have checked fuses and don't seem to find a problem our next step is to replace the ECM....

2009 Toyota corolla Automatic, 1.8L NON 1ZZFE
Died while Friend was driving .
No MIL, no history or pending codes.
Verified spark with a test plug and a ignition wire tester. Has spark while cranking.
Verified engine has fuel at injectors, removed rail and attempted to start while monitoring injectors, visually fuel is being sprayed out.
Verified compression by removing #2 spark plug, inserted finger into hole, compression forces my finger out of the cylinder head.
Security light comes one initially for 2 second when key is turned on, but goes away during cranking.
Cranks nicely, wont fire or start.
Not sure what's wrong, looking for an EFI or Ignition wiring diagram.

My son has a 09 Vibe 1.8L automatic and it won't start. Among other things, I also I want to check to see if it has spark and fuel pressure.
First of all, can I check for spark by looking at the signals into the coil packs? I realize that this won't actually tell me if there is spark at the plugs, but I'd like to know if the ECU is commanding spark or not. One of the coil packs was replaced a couple of months ago, so I'm fairly confident that it is OK. And it's hard to believe that all of the rest of them would suddenly have a problem.
As far as the fuel pressure is concerned, I don't see a valve on the fuel rail to connect a standard fuel pressure gauge. I'm assuming that I need to some how tap a gauge into the rubber supply line, prior to the metal line going to the fuel rail, but I'm not sure this is the recommended way.

I have a 2007 Lexus GS350 rear wheel drive. My battery died to this guy try to give me a jump and he connected the jumper box the wrong way, we had a little spark and then we try to connect the jumper the rite way but car will not start. I replaced the battery with a new battery, no start. the horn works but the rest is dead.
I was trying to locate a main fuse but was not able to. Do these cars have a main fuse? What should i look for.

I've got an intermittent issue with a 2009 Tiguan. Sometimes when starting (engine either warm or cold) almost as soon as letting go of the key, the engine will shut off. Multiple attempts to get it started result in the same issue, then for some reason it will start and run. There does not seem to be a pattern as to when it doesn't start.
The first time the dealer replaced the fuel pump control module, then when it happened again they said it was the fuel filter. It has now happened a third time.

I got a 2008 accent hatch basic model. Its got the 1.6 motor with 23k miles. It will not start at the moment. Battery is good, I am getting fuel. It is not getting spark, and my scanner wont link up to it. I don't know what else to trouble shoot. I am out of warranty car is a salvage title,car ran fine until today. I am thinking the ecu fried but I don't know? All fuses good. What can i check or how do I troubleshoot?

I have 06 F150 5.4L with a no start condition. The truck comes from another shop with no improvement. This is whats done so far, replaced plugs, checked the fuel control module 100% ok, we have fuel pressure at the rail, we have injector pulse ( niod light ), we have spark and we have a good battery. We tore down the timing cover because of the sound of the engine turning over like it was out of time when cranking.
We did find a tensioner totally destroyed so we replaced the timing as put it back together and replaced the oil pressure switch because we get this "low oil pressure" in the info center every time, we also get gray/black puffs of smoke out the tailpipe when turning over. So to sum it up we have spark, fuel, and battery and still nothing! We even flashed the ECU and still no fire/no start.

My 2009 Silverado 1500 with only 12,000 miles has begun intermittent display of all warning lights that are normally seen at start up. They stay on for 2-3 seconds and all gauges drop to -0-. When the warning lights go off, the gauges return to normal. It is not as prevalent after engine reaches normal operating temperature.

I've got a 2007 3.8 tg with about 46000mi on it and it will intermittently not start and only lights on the dash are the abs and esc lights on start up. Also will reset the clock and trip. the dealer has put in a new battery and immobilizer antenna, but the problem is still there, it was about 1k miles apart the last time it died after the battery replacement.

I have a 2009 Accent. Last year I started to have a hard start issue, very intermittent. It eventually got worse this year.
During the cold, it was never an issue, but during the summer damp or rainy days it occurred quite frequently.
It would turn over, but never start. If I pressed the gas peddle while starting it up, it usually would start the 2nd or 3rd time.
I changed the usual start up components; plugs, ignition coils, cam shaft position sensor, crankshaft sensor, and cleaned the throttle body.
None of those changes worked for the startup. When I removed my throttle body to fully clean it again, I noticed there was an extra air channel into the engine from the TB. Following this, I found the ISCA.
Removing, taking apart, and cleaning the idle speed control actuator seemed to have fixed the issue. It was so caked up with carbon deposit/build up, it couldn't fully rotate.
I used the throttle body cleaner to clean it out and then it began to spin freely (I removed it from the black sensor part first).
Since putting it back altogether, I haven't had a start up issue since.
Here are the notes from the service manual .....

It had no spark when I put a spark tester on, a few minutes later it started and runs fine. This has happened several months ago. Is their a way to test the spark control module.

I have absolutely loved my 2011 F-150 8 cyl since I bought it in 2013. I'm just now having my first issue...
For the past two weeks or so, I've had an issue with intermittently hard starting. It cranks like normal but doesn't turn over instantly. The longest its gone before starting has been about six seconds. Although originally happening only 10% of the time, its happening about 40% of the time over the past couple days. I had my mechanic take a look and the battery and starter all checked out fine.
Biggest problem was that it never did it for them making it hard for them to trouble-shoot. Thus far its always started, just takes an indescript amount of time in which to do it. The time of day doesn't seem to matter although afternoons in which I'm heading to lunch after being in the office for 3-4 hours seems the most common time.

I have a 2006 chevy impala LT 3.9 v6. Intermittently it wont start, crank it and it does nothing. All accessories work fine. Had a new starter installed, switched the relay it works on, had the ignition switch changed (twice), had the passlock system replaced, new keys for the ignition. Had the car to the dealer four, times. It doesn't happen all the time so it cant be reproduced at will. I just keep trying to start it and it will eventually start, it can be turning the key from 4 to 40 times. there's no rhyme or reason, some times it doesn't happen for 5 days, then it happens everyday for a week.. according to the dealer when they reproduced it it was the ignition switch. I doubt i got 2 bad ignition switches so i don't believe the error is being reported correctly. According to chevy they have no other reports of this..

Gremlin that causes the car to take a few tries to start when it is cold or damp? I've read that the crank sensor and fuel pump/fuel injection relays are possible culprits, but since the crank sensor is almost $100 I'm hesitant to throw money at an intermittent problem without a 100% diagnosis
-No codes in computer
-Brand new battery
-Mint NGK Platinum spark plugs
-Runs like a top once it starts
-5W20 synthetic oil
Usually it starts first flick of the key. Sometimes first flick fails no matter how long i hold it, then second flick it starts fine. If its really cold it sometimes takes up to 5 attempts. It cranks but doesn't "catch". The actual cranking itself is very strong with no hesitation which tells me it isn't starter, battery or thick oil.
