Hummer :: H3 Turns Over But Doesn't Start
Aug 18, 2016
My '07 H3 will turn over, but not start, but it only happens about once a week (4 times total as of now). When this happens, if I let it sit and try again in about 15 minutes it will start. I've spoken to 2 mechanics who state that they need to experience it happening to diagnose it. This means I would have to leave my H3 with them for potentially a full week which I can't do. How to handle this? I'd hate to be stranded somewhere in 115 degree heat with my 6-year old.

I have a 120k miles manual 2000 jetta vr6 12v. I was having check engine issues so i put in a reader and showed me problems at catalytic converter. I don't remember the code, and no longer have a reader...
I was told to replace the oxygen sensors in both banks as well which i did.
I opened up catalytic converter to inspect and now the car will get no spark, the engine turns, and the display shows engine stop.
I was also told to put the oxygen sensor further away with an extension cord but not sure if that plays a part.
Does the catalytic converter is causing it to not spark?
Could there be an issue with maybe a sensor at the crankshaft that checks for motion?
What the starting sequence and dependencies are or what failures I could have that prevent the spark?

My Dad's 2011 Raptor has been having starting issues for about a month now. He turns the key, it turns over, but doesn't actually start; the same thing happens if he tries to start using remote start. It will start once in awhile on a 2nd or 3rd try, after throwing the shifter back and forth from Drive through Reverse several times and trying again, but not most of the time.
It doesn't happen all the time, but every once in awhile, and always at random times.
The first time was accelerating at an intersection a month ago. A second or so after hitting the gas, the engine died in the middle of the intersection. He took the key out, threw the shifter back and forth, tried again, and it started right up without issues.
Later that night, he tried starting it after sitting for over an hour (and had started it several times before without problems), and it failed to start, even after 7 or 8 tries. He had it towed to the dealer the next morning. He even tried starting it that morning in the dealer parking lot, without success. Several technicians apparently started it several times later that day without any issues! They didn't fix or replace anything, because they didn't find any problems. When he got it back, it worked perfectly.
A couple weeks later, it had the same problem at the gas station, after getting a full tank. My Mom told him that her truck (a nearly identical '11 Raptor) had the exact same issues several times in the past, and her trick was to let all the lights in the truck turn off, then try starting. He did that, and it worked!
Tonight, the same issue emerged. He did everything that had 'worked' in the past, and it still failed to start after about 10 tries. It's headed to the dealer on Monday, but what it might be?!? I also want to add that when it starts, it starts flawlessly, without hesitation; as if there wasn't a problem.

Just replaced the fuel pump in my 99 Suburban. Replacement is an AC Delco unit. When I tried to start it, nothing. Engine turns over but doesn't start. Checked all connections and getting voltage down to new harness. replaced relay from GM dealership and also fuel filter. I used to hear the old pump prime when turning on the ignition but don't hear anything with the new pump. Could it be a bad pump out of the box?

Mazda B2300 2.3L 1995 model... About a week ago I ran my B2300 out of gas (or so I was convinced I was out of gas) because the engine quit running. After adding gas was unable to start it back up. It turns over but doesn't start.
Here's what we did to try and fix it:
1.) Replaced Fuel Filter
2.) Check the fuel pressure, and it was at 35 psi when the key was on
3.) Replaced all 8 spark plugs (4 cylinder truck btw)
4.) Checked spark of all 8 coil pack slots and 1st and 3rd slots (exhaust side) were not sparking. After replacing coil pack we received spark but truck still didn't start.
We're speculating on the possibility of it being the PCM (ECC).

So I just finished redoing my head gasket. Everything is hooked back up the way it was prior to the tear down. I'm getting spark, fuel, compression, timing was set correctly according to Haynes, turns over but just doesn't want to fully start up.

So a truck that was running fine Sat for 2 weeks. Battery died so i sent some coworkers to jump it. They tried using a welder which they didn't get turned down enough. Now the wiper motor stays on even without the key. Radio doesn't work but the dash light still comes on. With a new battery installed it turns over but doesn't start. I know something had to get fried but where to start. Thinking about replacing all fuses and relays...

I own a 2003 Hummer H2 with a 6.0 liter vortec engine with only 62,000 miles. At 50 to 55 mph 1500 to 2000 rpm the engine surges 300 to 400rpm with foot steady on the throttle. There is no engine light on and I,ve checked for codes with a code reader from the auto parts store. No error codes. I've cleaned the mass flow air sensor and throttle body with no change. My next thought was to replace the throttle actuator control sensor or accelerator pedal position sensor. I do enjoy working on my own vehicles so have been reluctant to take it into the shop.

Just had our '04 Odyssey with 162K miles to the Honda dealer to have some maintenance work done. Had cabin filter replaced for first time. Out of the service area, I started the engine fine, turned on heat/a-c, adjusting fan speed to high. There's a pronounced hummer noise coming from under the dash near the blower. It's a constant hum, not something associated with some debris that may have been dislodged or floated down into the blower area. The "pitch" of the hum increases/decreases with the blower fan speed. Service personnel came out, to include the manager, and they exposed the area where the filter was replaced; nothing out of place or loose.
Told me I could schedule another appointment to have them clean out the area inside where the filter and blower are located. Told them that service should be provided as a part of the filter replacement if it could be a concern. Although I'm not a car-savvy person, I'm thinking the problem is due to replacing the cabin filter: new filter, increased air flow (and there is a substantial increase of airflow out of the dash ducts) to the fan blower -- which as been operated with a dirty filter for probably a lot of miles and it has "worn" just right, that the increase in airflow is causing the hum. Fan blower spinning faster causing the hum?

I have a Droid X and when I turn the car off, the phone call goes into limbo. What I've been having to do is transfer the call from bluetooth to "handset" before I shut the car off so I can remain on the call.

Just recently bought a 07 Nissan Maxima SE. Has a few issues.
The car sun roof does not work at all. It worked the day I bought it though.
Has issues turning on. Cranks slowly then after a few seconds of struggle it turns. Didn't have this issue when I bought it.
Goes idle when first starting to drive. From park, I put the car in drive, or reverse, and let go of the brake, it basically does nothing. Engine is on as if it were in park or neutral, but the car doesnt move. When I press the gas it takes a few seconds before it decides to actually move.

I've been watching my mother's 1976 Fiat convertible this summer. It had been taken to the shop about 6 weeks ago and it's been running fine without any problems. I had to leave for about three weeks and now the car will not start.
When I turn the key in the ignition with the clutch engaged, the engine turns, but pressing down on the gas pedal has no effect. The engine doesn't rev nor does it catch. There is gas in the tank and clean oil. I checked all the connections I didn't find anything loose.

Last year I had an issue with starting my 1.8t Jetta Gli. Every couple of weeks, the car wouldn't start unless I keep trying or come back after a couple of hours. I then thought it was the cranks sensor and had it replaced. Unfortunately, the problem is back! The idle seems a little jumpy, car isn't as smooth as I'd like it to be. It also doesn't seem to have a strong start. I can't figure out what it exactly is, and I don't want to start changing random parts. I was debating on perhaps getting a new fuel pump, coilpacks...

It was running fine. tried to start and it just turns over. Also the fuel gauge doesn't move from an 1/8th of a tank. I took the filter line off, turned the key, and gas shoots out but the injectors don't spray at all. I poured some gas in the tbi and still just turns over without even trying to start.

Drove it last night, started fine. This morning she wouldn't start. Almost turns over but quits right before it would. Then a bunch of rapid clicks. Crank up the sound on the video to see what I mean. Got 46,800 miles.

My 07 Camry, 2.4 decided one morning not to start. Was fine when parked. I have changed the fuel pump and replaced the spark plugs and still nothing. Where to look next. It does turn over so I assumed it was either fuel or spark.

Recently replaced alternator and battery (was told by Brakes Plus that was the issue). The car (with no warning) sometimes just won't start. Whether after driving it or if it's been sitting for a day or two, sometimes it will only turn over once, but never start. Not sure if it's a timing issue or an issue with spark/fuel. There's also a loud click in time with engine rotation when it does start, may be an injector, also not sure with that.

It turns over but won't start. also makes a metallic sound it didn't do before while cranking.I changed battery a week ago and replaced air filter right before this started.Is it related or could it still be the starter even thou it's turning?
