Pontiac - Grandam :: 2004 V6 Won't Start Unless Battery Is First Disconnected

2004 Pontiac Grand Am GT, 3.4L V6...It only starts if the battery has been disconnected for at least an hour and then is immediately reconnected prior to use. Once the block is hot, however, it starts flawlessly and repeatedly every time. When the block cools, it won't start again unless I disconnect the battery and wait an hour. I did a bunch of tests without first disconnecting the battery: The fuel bar is pressurizing properly, the crankshaft position sensor works, the ignition control module has power, the plugs and wires are in good condition and have the right resistance. The coils are fine.

I did an OBD-II scan as well, no codes. However, unless I go through the disconnect-wait-reconnect procedure, there appears to be only a weak spark. I don't think it's the ignition security feature. There's no security light, performing a security reset does not fix anything, and the car starts repeatedly and reliably as long as the block is hot. I was wondering if it might be a failing sensor that has a thermal dependence? Should I look at the powertrain control module? The ignition control module?

Pontiac - Grandam :: 2004 - ABS Light On / Off?

This is on a 2004 Pontiac Grand AM.

The old GM ABS light problem. The lights were on a month ago and the left front hub was replaced, the light went out. They just came back on all of a sudden (coincided with the temperature dropping to 15F). The next day they were out. Then the next day they came back on. I couldn't get a code read with the basic scan tool.

Where should I start? I'm thinking of cleaning the speed sensor connectors and reseating with dialectic grease. Maybe they're dirty or a bit brittle due to age and the cold?

Pontiac - Grandam :: 2004 Tries To Turn Over But Won't Start

Have a 2004 Grand am that was having some problems starting:

1) The last 10 times it would start cold, but it would take about 5-10 seconds of turnover before actually starting.
2) After it started, it would start fine the rest of the day.

Now it will not start at all. Today is the coldest day of the year so far... 43 degrees. It tries to turn over. The security light came on once, but did not come on again (i know that's a common problem). (note: I have not seen it in person, but will later today). Either fuel or spark.

My thought: either fuel pump, fuel pump relay, sensor, wires/plugs, etc.

Pontiac - Grandam :: 2004 - Gas Smell And Shaking

I have a 2004 Pontiac Grand Am with a 3.4L engine. When I start my car after it has been sitting for a while, especially in the morning, the engine shutters making the car shake when it is put into Reverse and Drive. Plus a horrible gas smell come from the hood and into the heating vents. So to alleviate the shaking I let the car run for several minutes which in turn makes the gas smell worse. The smell continues to get worse when the car is stopped at a alight or stop sign. to eventually go away as the car heats up. The check engine light blinks with the shaking then disappears but eventually stayed on with a cylinder misfire code. I took it to a shop who told me that was the head gaskets.

Pontiac - Grandam :: 2004 - All Dashboard Functions Failed

I have a 2004 Grand Am and a month or so ago, I started it up and all the dashboard functions failed. RPM, speedometer, odometer, fuel, temp all stopped working. The dials read zero and the odo did readout but did not advance. Some of the idiot lights also came on. The radio is also dead and is either totally blank or reads "LOC", but the air blows fine. Also the key fob will not lock/unlock and neither will the door controls lock the doors but the windows work. It was fine the next day. Now it has returned and has lasted 2 days so far.

Full disclosure: I did replace the PCM in December because something in the Passlock system was failing and not letting me start the car. The replacement PCM is an exact replacement that has had the Passlock code commented out. There have been zero problems with the PCM since then.

Pontiac - Grandam :: 2004 V6 - Rough Idle And Hesitation

I own a 2004 Pontiac Grand Am V6... recently it has developed a rough idle - kind of like the car is hiccuping - and it hesitates when I accelerate from a stop. Now, it doesn't have issues changing gears so I'm not inclined to believe its a transmission issue...thought it might be the fuel filter, but I changed it and that did nothing.. I'm not getting a check engine light, which is frustrating because if I try to pull the codes it won't throw me any... so it's a guessing game now. I've gotten mixed reviews - anything from a bad catalytic converter to a faulty O2 sensor or idle air controller or a bad head gasket.. but my exhaust is completely clean...others say maybe its bad spark plug wires or other electrical issue (which is a whole other ball game) or possibly bad fuel injectors causing a misfire?

Pontiac - Grandam :: 2004 Won't Start After Radio Install

I have A 2004 Pontiac grand am and am trying to install a non factory stereo.

Well now after I have done this my blinkers don't work nor do my wipers and my car won't start.

Pontiac - Grandam :: 2004 Will Not Restart On Warm Or Hot Humid Days

2004 pontiac grand am, after driving and shutting off the car, it will not restart or stalls out while waiting at traffic lights. When I try to restart the car, all I get is clicking sounds, only does this on warm or hot humid days. The dealer told me to just hold down the gas pedal and crank the engine till it restarts. I have tried the turning on the key for a minute, wait, then turn the key back off, and then to restart, but that doesn't work either. If I wait for a good ten minutes, the car usually starts. When I turn on the key I do hear the fuel pump kick in. I have replaced the fuel regulator, ignition switch, keys, computer chip in the ignition system, battery, and starter- twice. I have heard that it could be a crankshaft sensor? No codes are showing up when this happens.

Pontiac - Grandam :: 2004 - Cranks Fast Starts Slow

I will try my best to describe the problem:When the car sits for quite a few hours it basically will try to fire up , but can take 4,5,6 seconds before it will actually start. It is a fast turn over just as if your car was going to start normally, but it just takes time. This is not a slow turn over as in a battery problem, or a very cold weather thick oil problem.After the car starts the initial time, you can turn it off and start it and it fires right up.

When I turn the key to the on position, I can hear the Fuel Pump. I have tried doing this a few times in a row, but it doesn't work for the initial start.

This has been going on for about 8 months, and I have basically ignored the problem. The last few starts the same issue persisted except instead of firing up after 4,5,6 seconds it just shuts off. After this I turn the key over and it still fires right up.

Pontiac - Grandam :: 2004 - Compressor Is Working But AC Stopped Blowing Air

Bought an 04' Pontiac Grand. AC worked fine on the test drive then after a few weeks the AC stopped blowing air. I can feel the compressor is working and the air is being conditioned but the blower motor does not turn on. I've tried using all the speeds and none of them work. I do not believe the controls are to blame but rather either

A.) resister or
B.) connector(s) or
C.) blown blower motor.

Pontiac - Grandam :: 2004 - Low Coolant Light Coming On / Smoke Blowing Out From Under The Hood

My car has had issues with the "low coolant" light coming on for over a year. No one could ever find a leak, the coolant level was always pretty good, and I never had a puddle.

Recently, my mechanic suspected it was the heater core. Since I earn early childhood teacher wages, I couldn't afford to have it fixed. As a temporary solution, he bypassed the heater core in order to buy me some time. Now, I have no heat or defrost. But also, the leak has gone out of control! I have to put coolant in daily, and I always have a puddle under my car when I am leaving work at the end of the day.

My car's newest trick is smoke, coming from under the hood, and the fresh smell of burning coolant. However, temperature is fine, at least that's what the gauge says.

Prius (2004-09) :: 2005 - Battery Not Working - Dying Repeatedly At 120,000 Miles

Trying to figure out whether to fix or scrap our 2005 Prius with 193,000 miles and a mysterious 12V battery problem. What would you do in my situation?

We've had a recurring problem with the 12V accessory battery: I have replaced it myself three times. The last failure was the most mysterious, because after replacing the 12V battery for the third time, I conducted nearly daily voltage tests using the Prius' "secret" vehicle signal check. Voltage coming off of the 12V was normal, if not high the entire time in all of the Prius's various starting and ready modes. I wired up a solar panel to trickle-charge the 12V battery when we weren't around, and we plugged the 12V in at night to a trickle charger to keep the battery topped up.

Nonetheless the day came a few months after the latest replacement when we had our usual 12V failure symptoms: the time on the clock started resetting, the car didn't turn on on the first press, the Prius computer rebooted, and eventually the car wouldn't start without a jump start. This has been super-frustrating, and googling around, I haven't been impressed by people's reported experiences trying to have the dealer try to resolve such problems. My worry is that a dealer repair person will change the accessory 12V battery without fixing the underlying problem. I would suspect a parasitic draw somewhere, but voltage tests when the car was overnighted without any kind of charging did not suggest a serious voltage draw on the 12V battery.

Other details about the car: our keyless entry hasn't worked for several years (dead batteries in the key fob?) and we open the car manually using the key each time. We stick the fob in the slot each time we want to start it. MPG is comparatively low vs. other Priuses, perhaps 44-45 MPG, and lower when the 12V battery starts to die (37-40). I have had the car serviced (oil, etc.) like clockwork every three months; recently, I've noticed the engine is starting to burn oil a bit (level is reported low on each change).

Most of the driving has been done in the flats and the heat of California's Central Valley, and we've put something like 120,000 miles on it just in the last five years. Besides the fact that the 12V battery keeps dying, the car has been very reliable.

We just inherited a free Prius with just 60,000 miles on it, and I have a 1993 Camry with 150k miles on the chassis and maybe 60k miles on the replacement engine I had dropped into it a few years ago. The Camry just passed California's smog test and seems to be running well. We don't want or need three cars.

Our choice is to try to fix the Prius with 193k miles on it and donate the Camry (which gets about 20 miles to the gallon, the horror...), or keep the Camry and donate the Prius. My instinct is to not drop thousands of dollars into the high-mileage Prius, especially if these issues might be pointing to a dying main battery.

Pontiac - Grandam :: All Of Night Light Went Off

Last night when I was driving home, I noticed that all of my "night lights" were off. The lights on the speedometer, gas gauge, gear shift, etc. did not seem to be working, but all of my system warning lights (Traction, Brake, etc) seemed to be fine. I tried to turn the car on and off a few times and also tried fiddling with the lights manually. Nothing seemed to be working.

Pontiac - Grandam :: 2000 - Won't Turn Over?

I have a 2000 grand am Gt with 3400 motor it started up just fine went to turn around in the drive way the dash lights came on where the ABS sensor is bad, but if u shut it off and started it back up they would go out so i shut it down and went to start it back up and all it does is click, so i thought it was the starter and replaced it, still only clicks. I called GM dealership they said more then likely it is the plastic piece the ignition switch goes in to so i just replaced it and does the same thing.

Prius (2004-09) :: 2002 Toyota Keeps Dying With 3191 Code After 12V Battery Charge

My 2002 Toyota Prius keeps dying (triangle of death and OBD Code 3191) after running smoothly for a few seconds each time I start the engine. Clearing the DTC code allows restart. But the check engine light and triangle of death keep returning after a few seconds.

It has been doing all this since I recharged the 12V battery (which had been drained completely by a dome light left on for 3 days). Initial attempts to recharge the 12V battery were causing current spikes at charger, and (relay?) clicking sound under the hood. So I disconnected positive battery cable and charged the battery in isolation, then reconnected it to the vehicle after charging was complete.

When I reconnected the recharged 12V battery the vehicle (honking horn) alarm went off. But that stopped when I unlocked door with key. It may not be related, but I'm also hearing a fan-like sound (under driver seat) when ignition key is in run position. I don't recall hearing that sound in the past.
