Chevrolet - Cobalt :: 2009 Will Not Start In Cold But Only Sometimes

My Chevy Cobalt will not start when it is cold (when water freezes)...but only sometimes. When you go to start the engine, it will initially turn over but does not ignite. Then, the second time if you turn the key normally no sound will emit. However, if you put the key in and only turn to get the lights on the dash to come on and THEN turn the key, it will turn over, but no dice. This past time a code "engine pwr reduced" came up, but that doesn't always happen. When you wait four hours or more, it will start like normal accompanied by the check engine light. The check engine light goes off the second time you start it after the non-start.

I have taken it to a mechanic and they have not been able to reproduce the problem, even when it was cold enough to theoretically have happened. He said it might be an issue with the body module which explains why the ignition switch code comes up when you run it through a computer, but since this is such an expensive fix he said he can't recommend I get it done until we know for sure. So there is a pattern, this happens about every 2 months and then the issue clears up for a while.

What is going on??? Will there ever be a way to tell what is wrong (and fix it) without a mechanic reproducing the issue?

Intrigue :: 2001 V6 Not Starting Due To Cold Weather

2001 Intrigue 3.3 L v6

Due to the cold weather, seems the battery could not start the car. I removed the battery to trickle charge it overnight in the house, and hooked it back up in the morning. It seemed to have sufficient charge to power the starter motor, but the engine would not turn over. I could hear a whirring sound whenever the key was turned, and the sound stopped whenever the key was turned off.

I am suspecting that the starter motor somehow is not engaging with the engine flywheel?

Passat (B5) :: 2004 - Delayed Starting In Cold Weather

2004 Passat 1.8t that is intermittently not starting. The problem only happens when the car is cold. When I turn the key, the car cranks just fine but will not start. All of the dash lights light up and I had the battery tested and it is fine. Tonight it took about 5 minutes of repeated cranking and waiting before the car started.

After a 15-minute trip home and it had a chance to warm up, the car starts just fine. I've taken it to my mechanic but they haven't been able to replicate the problem. I'm thinking about leaving it overnight just so they'll be able to replicate it.

Not sure if it could be related, but I just had a coil replaced a few weeks ago (the coil was <1 year old). The plugs are only 3 months old.

Sonata I45 (YF - 2011+) :: Engine Has Inconvenience Starting Only During Cold Weather

So I have a weird situation. My Sonata GS with the 2.4 engine has trouble starting ONLY during cold weather (-2 or colder) if it's been sitting for a few hours. If the weather is warm, then it starts fine most of the time. The car tries to 'fire' for about 45 seconds before it does; and 'fires' with no hesitation at that point. The car runs fine, no hesitation or rough idle. I've cleaned the intake system to make sure it's not clogged or dirty, replaced the air filter, cleaned the MAP and throttle body. My battery died a few weeks ago, so I've even replaced that. What this could be? Everything I've researched or looked into would throw a code, or have symptoms while driving...yet it runs fine once it's started, and no codes/lights are showing. Don't want to just start swapping parts hoping to find the problem...

Ford - Fusion :: 2006 - Hard Starting In Cold Weather

My 2006 Ford Fusion SE V6 has trouble starting in cold weather. Once it starts, it's fine throughout the day, but once it sits a long time, like overnight, it has trouble starting in the morning. If it had a carburetor, I'd say the choke wasn't working. The dealership couldn't figure it out a few years back. I even tried a new battery and that didn't work. Is there a sensor that detects cold weather and increases fuel flow or chokes off air flow for richer starting mixture that could be failing?

Chevy - Cobalt :: Engine Sounds With A Ticking Noise

I have a chevy cobalt and recently just upgraded the pistons and rods. I've driven it about 1k miles since the replacement and it just started making a ticking noise. It sounds like its up in the head. I've changed my timing chain tensioner bolt, also replaced the rod bearings. Everything lines up at TDC but around 2-3k rpm it starts ticking. I'm also getting a P0300 code. When I pop the hood I hear a leak somewhere but can't find it. I've also tried using carb cleaner at the injectors to see if a gas leak was accruing, but nothing changed in the rpms.

Chevy - Cobalt :: 2006 - Clicking Sound Behind Dash?

Recently purchased a used 2006 Chevy cobalt, seems like an alright car so far. But lately when I turn on the car and also sometimes when I switch the heat on there is a clicking sound behind the dash on the passengers side that lasts less then 10 seconds. Is it safe to drive on? Or am I causing some great internal damage by just living with the noise instead of repairing it asap (bc tight on cash rn)?

Ford F-150 (2004-2008) :: 2005 - Hard Starting In Cold Weather

How to diagnose what I think is a failing alternator?

Here are the symptoms:

- Hard starting in cold weather
- Battery not at full voltage when truck is parked (usually around 11.5-12 volts. I have been putting a charger on it some nights)
- Lights seem to dim when I've got accessories running, like heater fan, heated seats etc. Lights get brighter with engine RPM, like when pulling away from an intersection.

What's my next step to diagnose this? I did a search, and didn't see anything. My battery is probably still under warranty, so if that's the issue, it should be a free fix. How hard is it to install an alternator in a 2005 with 5.4L engine?

Chevy - Cobalt :: 2005 - Sound Like Trying To Lock And Unlock When Car Is Running

The locks on my 2005 Chevy cobalt sound like they are trying to lock and unlock when the car is running. The locks themselves don't move while this is happening. It has been to the dealer twice and no luck. The first time it went in, they said the left and right lock switches were shorted so they replaced them. The second time it went in they said that the ground wires were corroded and they fixed that problem. The car drove fine for a few days, now the same problem is occurring.

Volvo :: 960 Wagon Intermittent Starting In Both Warm And Cold Weather / Turns Over Fine

Vehicle: 1995 960 wagon

Background: Exhibits intermittent no-start behavior in both warm and cold weather, wet and dry weather, having sat overnight, or only sitting a few minutes. Turns over fine, but won't start. Sunday, it started fine several times, went to Home Depot, wouldn't start. Called a friend to pick me up. When he was almost there, I tried it again and it started back fine. Been in shop a few times, they played around with a few electrical connections, battery cables and grounds to injectors. Also replaced fuel pump. I have not verified if it is a fuel or spark problem, I just bought a FI fuel pressure gauge last night.

Once started, it does fine. It never stalls or cuts out. That is why I am leaning toward a CPS (that's what jeep people call it.) Sometimes, under the slow cranking speed (relative to idle) the signal is too weak to be useful. However, during idle and normal operation, the flywheel is moving fast enough that the signal is much stronger (being a magnetic pickup). Thus, the reason it only happens during starting, not during running.

Here's my current working theory: Bad crank position sensor (is that Volvo people call it?)

This is the only part I can think of that would cause this. A fuel pump problem would probably show up during running. I think the pump also receives a signal from the cam sensor, so if that sensor were the problem, it would happen during running too, not just starting. It the cam sensor an optical sensor? Shouldn't cause it to not start, although it might cause a difficult start.

I have a 95 Chevy S10 pickup with the TBI motor, Z engine code, that has begun to not start on occasion. The engine cranks but does not fire at all everything else seems normal. This only seems to happen in the morning so might be cold related. If the truck starts I can drive it all day without any starting issues.

Starting - Saturn - Weather - Ion :: Won't Start When Temperature Drop To Single Digits And Below

When the temperatures drop to the single digits and below, my car won't start. It won't even turn over! I turn the key and there's nothing. So, I sit in the car and then turn the key again. I wait. Then turn the key again. Within about 5-10 minutes, the car starts and its good to go! I've had a new battery installed. And even with the new battery, it does the same thing. At the shop, they check the battery and say it's fine.

Chevrolet - 1500 :: 1996 Chevy Engine Hard To Start When Cold

I have a 1996 Chevy Cheyenne pickup with a fuel injected small block that has 50k miles. Earlier this summer the truck developed a problem where it is very hard to start when cold (after sitting overnight or after sitting for many hours on my flat driveway). When the engine is cold (say the first start of the day) I can only get it to start by giving small bursts of cranking power to the starter. That is, it won’t start if I hold the key in the cranking position but is more likely to start if I give it a short burst of cranking power (when I hold the key in “start” position) for a second or two.After the first start of the day, the engine runs fine and subsequent starts are quick and normal. The “Check Engine” light is not on and there are no trouble codes…. Other than hard starting there are no issues with engine performance.

Chevrolet - Cobalt :: 2006 Not Starting Up Right After Getting Gas

I currently own a 2006 Chevy Cobalt. For the past few months it had a problem that every time I get gas when I go to start the car up I have to pump the gas pedal and crank it at the same time to get it to start running. Once its running I have to either get driving pronto or sit and it park and accelerate it a little for a bit to keep the car running. If I let go of the gas pedal the car will clunk and shut off. If I drive off after a few blocks it’ll work fine and I won’t have the problem again until I put more gas in it. Occasionally when at a light or stop sign while in drive the car will clunk a little but normally stop after few seconds.

I went to AutoZone and they told me I had a pressure thing (can’t remember fully) but to replace the gas cap. Which the car tells every so often to check my gas cap. Well 4-5 gas caps later problem still there. What it could be or how to fix it, last resort is to take it to the mechanic and pay a nice bill for a fix.
