Grand Prix :: PO441 - Would A Leaking Canister Set This Code Off
Aug 5, 2014
1997 Grand Prix GT N/A. 175,000. I keep getting this code about once every two weeks. I'll clear it and doesn't come back until then. I've had passengers in the back seat smell gas so I'm suspecting the vapor canister. Would a leaking canister set this code off? I checked all the vacuum lines to the purge solenoid and seem fine. Is the canister in the drivers side rear wheel well? I need to get in there and check if it's leaking. I'm having no driving issues however my gas consumption seems to be a bit more than usual. I checked the FPR and no fuel contamination.

I am a proud owner of '97 Grand Prix GTP, it has always been a great car with really low maintenance for me. A few days ago I noticed a mild fuel smell and I checked the gas cap, the external fuel filter, etc... Then I lifted the hood and I saw that one of the two fuel lines that run between the firewall and the brake fluid reservoir had a seepage leak in front of the factory loom that secures both lines before going over the supercharger and on to the fuel rail. A fuel leak needs to be repaired immediately, so this is where I am so far.
I noticed that the leaking fuel line is actual a rubber/plastic fuel hose that is covered by a plastic heat proof cover that protects the hose. It runs from the firewall to the fuel rail along side another fuel line of the same size (a supply & return line I believe). Just before going over the supercharger they both have quick connect metal ends that meet two metal fuel lines that end up at the fuel rail. My current issue is that this plastic/rubber hose section of fuel line is discontinued and no longer available to order according to my local GM parts dealer. The way I see it, hunting down this part can be Plan A and Plan B can be duplicating this hose by making it with high pressure fuel injection hoses and the appropriate quick connect fittings.

2000 Grand Prix GTP has code P1629, car will run for 3 sec with black master key and then die. Security light in dash is flashing when this happens. Tried the 30 minute relearn for PK3 with no luck. It will start and stay running with the grey Valet key which is perplexing to me. As of right now I am siding with replacing cylinder and ignition switch after everything I've read on the subject.

I bought my 2001 Grand Prix with a 3.8 liter (non supercharged) earlier this year. Within the first month, the check engine light came on with a P0410 code. Took it to the shop here at the auction that I work at to get repaired. He ran the diagnostics on it and found that the air pump wasn't working. He pulled it out and it was full of water, due to the air inlet being so low. So, he replaced the air pump and re routed the air inlet so that it was higher up into the engine compartment. That same night, the light came back on, so I brought it back in the next day. The relay failed and popped the fuse. Replaced both, and the light was off for a full day.
Got ready to take it in for its emissions test today, and the light came back on again. The air pump is not working, again. Turns out that the previous owner had replaced the air pump twice (once with aftermarket, and once with an OEM unit) because of the water build up and freezing the first time. I am not aware of any GM service bulletins, but there has to be something that is taking out these pumps. The only things not replaced on the secondary air system is the lower check valve and solenoid. So, what could be causing the pumps to fail prematurely?

About a month ago I had my SES light go on and I took it to the auto parts store and they said it was a small emissions leak. I am not sure of the code though. I took my car to the shop and they said that a sensor that had something to do with the exhaust was bad or unplugged.
My SES light came back on about about a week ago and I had it tested and it said the same thing. "Small emissions leak" This time I got the code and its P0442. The shop is closed today and tomarrow so what and where the sensor is located? Or if its the same thing?

1997 Grand Prix 3.8 N/A 181,000 ... I have been getting a misfire only on cylinder 4 which has become more frequent. It "only" happens after the car has warmed up and I turn it off for a few minutes, for instance going in to pay for gas. When I start, it immediately starts to miss but as soon as I hit the accelerator it evens out and runs great, every time. I replaced plugs and wires two years ago with stock.
Upper and lower intake manifold gaskets were replaced around 110,000. All three coil packs have been replaced with original GM packs. I replaced my EGR valve last year due to the original was sticking. My throttle body was cleaned about four years ago. I've seafoamed through brake booster and the rest in gas tank.
I'm stumped that it corrects itself right away by giving it gas. The SES light always come on but goes off on it's own after a few cycles.

I just bought a new 2001 Grand Prix. I am not completely car savvy, but I know a few things for a lady.
The battery won't hold a charge.
and the computer diagnostic tester thing says the Headlamp Relay is malfunctioning.

My wife's car has 83000 miles on it. We bought it as a factory certified pre-owned vehicle with about 1800 miles on it and it came with the warranty. For the last two years the check engine light comes on with code 441 I don't worry about it till time to get inspection sticker here in Texas. I have been about to reset the computer and drive it till the computer is ready to be inspected and it has passed for two years. Now it won't reset and I have tried to test the vacuum switch and it seems to click when I apply voltage but light won't go off. This code can cost up to about 2000.00 to try and detect. I am not interested in having the dealership keep guessing on my dime.

I have a 95 Grand Prix 3.1L and I can't turn my key. You can put it in and take it out, but it won't turn whatsoever. It's stuck in my driveway and I've tried just about everything to get it to turn.

I'm pulling the engine to overhaul. I've borrowed a hoist and think I'm ready to lift the engine out, but I don't know how to strap the engine to the hoist. I first thought of using the brackets with the eyelets bolted to each head and bought chain and hooks. But I had to remove the rear bracket so I could remove the rear exhaust manifold so I could remove that darn rear engine-transaxle bolt. (That really bites because I want to have the exhaust manifolds on when dropping it back in.)
Are those brackets intended for lifting the engine? If so, I could reinstall the back bracket and give it a go.
Searched the internet for info but didn't find much. Did find a 3800 being lifted with two straps completely under the engine.
Also, the engine-transaxle joint hasn't cracked open yet. I'm guessing it's because they're stuck after 198k miles and will eventually separate. But I did not find one of the engine-transaxle bolts mentioned in the 98 FSM: front lower (#1). I don't see how I could have missed it ; maybe the 99 doesn't have it?

I have a 2000 Grand Prix with a 3.8L engine that will not start. When I turn the key to the run position, the headlights and the dash lights come on, but when I turn the key to the start position, the lights go dim and nothing happens. No sound from the starter. I checked the battery and the starter and they are good. I installed a new positive battery cable. Still works the same. Not sure what else to check.

When you are accelerating anywhere from half to full throttle it may cut out at any given time. The RPM will drop down, it may bounce up and down for a bit and recover, or it will drop all the way down and stall. If you let off the gas it may or may not recover. If it stalls so far from the tests I have done if you never shut the key off it will never restart again. If you shut the key off and wait from 5 to 10 minutes it will all of a sudden restart normally like nothing ever happened. If you try to restart it immediately even if you shut the key off and back on it will not start.
When it does not start when I am attempting to start: Fuel pressure according to my gauge is between 55 and 60 psi. Inline spark tester shows that it is getting a spark. Engine sounds normal while cranking so in other words compression sounds normal. I have an LED test light rigged up showing when an injector fires, and it does show electrical activity going to the injector when it opens (flashes). Only clue is that it SEEMS dimmer when it wont start, but I have no clue if thats how it normally is on start up. Its only a slight difference from the brightness of a normal idle brightness. I have a snap on scanner hooked up, nothing that I know of looks abnormal in the data and it will not throw codes when this happens.
Parts I have changed or cleaned so far: Changed the fuel filter, crank sensor, cam sensor, ignition module, and MAF sensor. Cleaned the throttle body. When the car is working normally it runs strong, good power, smooth. Starts great normally.

What may be causing my car to harshly shift fron 1st to 2nd and then from 2nd the 3rd. One solution some one had was to replace the:
"TPS (throttle position sensor). The other reason for hard shift is a worn Boost valve and will need to be replaced, or a faulty transmission fluid EPC (electronic pressures control valve). Both Boost valve and EPC are located in the Valve Body and can be replaced with out dropping the valve body, but have to drop the transmission pan".
I did just recently top off the tranny fluid because it was running a bit low but there is no leak....

Last year my a/c worked off and on. so far now its not working at all. Compressor isn't kicking on. i bought a bottle of the EZchill refrigerant to recharge the system. I took the relay out and added 12+ to the pin to kick on the compressor. Even with the compressor running the gauges are in the blue range which is the normal operating range. With the compressor running, the air is cold but when i stick the relay back in the compressor wont kick back on. I tested the relay and its fine. Also the compressor is rattling.

Last weekend, I saw fluid under the right side of the car when in a parking lot and found a rather large puddle of almost clear, oily fluid on the garage floor when I got home. I figured it was power steering fluid. I just finished a rebuild a couple months ago but the old power steering pump wasn't changed, so I was guessing a leaky hose or seal.
I quit driving the vehicle. A much smaller puddle, barely more than a spot, appeared. But it was much nearer the front of the vehicle than the PS pump. And the PS pump fluid level is still full.
Not much evidence of dripping fluid in the engine compartment. Is it possible that the new motor mount installed just a few months ago cracked and leaked its fluid already? Don't know how I could verify that without removing the mount. I'm at a loss for the source of the fluid.

Driving last night and my 08 died after searching I found the ICM fuse was blown. I replaced the fuse and now it has a misfire on cylinder 6. I have changed the coil with no luck. I replaced the plugs and wires about 2 weeks ago and I don't find any problem with the plug or wire. I checked at the coil and there is no spark at all on cylinder 6. I was thinking the ICM is bad but was wanting some opinions.

I have an 2002 GT with a 3.8 in it. Two wires broke on my harness that plugs into the shift solenoid so it will not shift out of park.
I got a new harness and wired it how it was wired before but it is not working when I plug it back in. Is there a way to test the new harness to make sure it works?

I have a 2000 GP GTP. I went over a speed bump to fast one day, and parked my car. When I got back into the car the next morning, I tried to put my car into drive and it wouldn't accelerate or move. So I put it into lower gear, 1st to be specific, and the car moved normally. I drove like that for a few days with no problem. Then days later I did the same thing, went over a speed bump to fast and now the vehicle wont move at all unless I put it in reverse.
