Chevrolet - Lumina :: 1997 - Vacuum In Gas Tank
Jan 11, 2014
I have 30k on my 97 Chevy Lumina. there is so much vacuum in the gas tank that it crushed the tank. I have replaced the tank but don't know what the problem is. Have taken it to three different shops and got three different opinions. One shop replaced the purge solenoid, no luck. Another said there is no fuel tank pressure data and want to drop the tank and check the sensor. the error code they read is p0440. The other replaced the evap canister. Am driving without the gas cap to protect new tank.I don't want to pay for another unnecessary repair and am sure I can repair it myself but want to be cartain I have it right. Also I didn't realize there was a pressure sensor in the tank. They also said I could have a restricted vent valve or canister.

For the last couple of weeks I've had a clunking sound coming from the right rear end of my 1997 Lumina when I drive over bumps. Took it to a garage the other day and discovered that the area around the right rear shock (strut?) mount is severely rusted. I assume that other probably causes were checked, but the mechanic was suggesting that this was the reason for the noises I've been hearing. From what I saw, and what the mechanic said, the shock mount is integrated into the wheel well of the vehicle. There's little good metal left in order to support the shock and coil spring, so obviously this situation needs to be addressed, but can this really be the source of the noise? His idea of a fix was that I would have to find a donor car with good metal and use that to replace the rusted wheel well on mine. Not something that his shop can do, but I'm sure there are others in my area that can.

I'm hearing a muffled thump in the center rear of my '97 Lumina about 2 minutes after I turn off the engine. It comes in a series of 2 thumps. This started about a week ago and now the thumping is occurring when I'm in a slow idle--just a series of two thumps. Maybe it's releasing pressure? What this could be?

My check engine light keeps coming on. I've had a couple of mechanics look at this and they say the code indicates the transmission is going out. the transmissions does not slip or have any signs of going out.

Driver's side strut makes noise, been told by a mechanic it is nothing to worry about just the rubber mount on the strut. Makes noise when accelerating from a dead stop or sometimes turning. It is not a metallic sound. Can i get buy with changing the rubber mount on top of the strut or is it down in the strut itself so the strut needs to be replaced? 1997 Chevrolet Lumina car 4 door....

I bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????

How can I find a vacuum leak? I hear hissing from driver side. I used 2 cans of starter spray and on throttle cleaner. No change in rpm.
I'm on the of my Latin. If I pull the throttle short and raise the rpm I hear a loud air soak. But I can't locate it. Can be the egr, lower intake upper intake or fuel interceptor. I begin to hate the car.

Ok, so my 1994 chevy lumina euro coupe 3.1L has started stalling now that it is getting colder outside. This morning on my way to school. I started my car and put it in reverse and backed out a little bit and it stalled out. So I started it back up and it was ok. It acted like it was going to stall out again but it didn't. This has happened a total of 3 times now in the past week.
Also I do have a fuel problem as well. My car smells of VERY STRONG gas when sitting. And I am getting 11.9 mpg in the city and 14.7 mpg on the highway. Oh, and one more thing. I slowly lose coolant in my reservoir tank. It is a very slow leak and only leaks while the car runs.

1995 Chevy Lumina 3.1L Sedan with ~182K mi
Over the past 6 months, I have noticed fuel odor just about any time I turn off the vehicle, and I am also experiencing progressively higher levels of fuel tank pressure each time I remove the fuel cap. The fuel tank pressure seems to be greater the lower the level of fuel in the tank whenever I remove the cap. 6 months ago (~Sept) it was only a slight "hissing" periodically when removing the cap to fuel up, but now it occurs at every fill up and seems to have enough pressure to push the cap entirely off had I not been careful to slowly loosen the cap to relieve the pressure.
The entire fuel pump and sending unit assembly in addition to the tank and filter were all replaced about 4 years ago in May 2010 or about 28K mi ago. The issue has just come up progressively over the last 6 months.
Today, I inspected the evap. emission components and lines from the tank to the canister to the purge solenoid mounted on the rear of the engine. All lines are connected and seem to be in operable condition. The line from the canister to the purge valve mounted on the engine is completely free with no obstructions. I blew out the line with compressed air and absolutely no exiting particulates were observed. The lines on the bottom of the canister did not show any signs of wet fuel and there were no carbon particles present in the lines from what I could tell from disconnecting and inspecting. The vapor line from the tank to the carbon canister is not kinked or pinched in any manner.
I believe there is a fuel vapor check valve that resides inside the tank connected to the fuel pump assembly/sending unit. This was all replaced as a single unit as mentioned above. I am thinking this check valve may not be functioning properly and not allowing the vapor to escape into the carbon canister. I tried to apply slight pressure and vacuum on the vapor line connected to the check valve on the tank but no air was able to move in or out even with the gas cap off. However, I do have a full tank of gas right now, so I imagine the check valve will be closed.
The check engine light is not on but since this is an OBDI vehicle I am not sure there are any evap. emission codes anyway.
How can I test the gas tank vapor check valve? How can I test the vapor purge solenoid located on the rear of the engine? What malfunctioning component could be causing the excessive fuel tank pressure.

My check engine lite stays on. I was told it MIGHT be the vacuum seal on the gas tank. How much should I expect to pay to get this fixed? and how long should this repair take?

I have a 96 chevy lumina. My brake lights will not come on. My 3rd will not either. I have changed the bulbs, checked the fuses, checked and replaced my brake light switch in my brake pedal with no success. I have half of my dash lights so I am thinking maybe a short?? I have my tail lights, but no brake lights.

Got no heat in my 1995 Chevy Lumina passenger car with 3100 engine. Have replaced thermostat, water pump and replaced freeze plug that had a pinhole in it. Heater still blowing cold air and temp gage only moves slightly - stays in low range never reaches normal operating temp. what's causing the problem and how to fix it?

Yesterday my 1996 Mercedes C220 would not start. It cranked like crazy but would not fire. Some things I suspect contributed: The gas tank was below 1/4 full. It was cold ... about 25F. The night before I had put 140 lb. of sand in the trunk just before driving it about 15 miles home and parking it. My theory was that because of the weight of the sand and the low gas level, gas was not able to get to the fuel pump.
So this morning I was going to put in a couple gallons of gas from my garage gas can. When I opened the gas cap there was a serious whoosh of air into the tank; there had been a substantial vacuum inside the tank. I put the cap back on, without adding any gas (the sand was still in the trunk), and the car started right up. Here's my question(s):
1) Did the sand contribute in any way to the problem?;
2) Did the low gas level contribute?;
3) Did the cold weather contribute?;
4) Do I have a mechanical problem I need to take care of?

My car has started to on occasion not have any power when I turn key. I can try it several times and then poof, the power is there and it stars with no trouble. When I say no power, there is nothing, no dash lights no sound, Absolutely nothing!

My wife's '93 Chevy Lumina has a strange habit of not starting unless I charge the battery overnight. The lights don't dim when I turn the key which would normally tell me that the battery and connections are fine, but the solenoid won't energize. If I trickle charge the battery overnight it will start fine. Now this generally happens after the car has been sitting for an extended period of time. Computer maybe?

I drive a 2000 Chevrolet Lumina. The car frequently goes out of alignment. Best case scenario, I have to get an alignment done once a month. The last time I had an alignment done on it, the mechanic said one of the machine settings was not listed & they could only align two of the settings. I guess he meant two out of camber/toe/caster. Also, I was rear ended in June 2012. The car seems to have lost capability to stay in alignment. Why is this? Do I need a new suspension? Do I need to have certain parts looked at to see why the car can not stay in alignment?

My 1999 VW Passat has a check engine P0411, P0422, so I looked for any damaged vacuum lines and found one that was all melted coming out of the blue vacuum reservoir tank in the front left lower bumper area. The line was broken off and I cannot figure out where this line is supposed to go.

Recently my '92 Chevy Lumina (115,600 miles) has taken to not "firing" after I turn it on. It has a brand-new battery and altenator so there's plenty of current. I usually try to get it running 3 or 4 times and if it won't go, I leave it so as to not wear down the battery. It's as if it's not getting any fuel and yes, I do have gas in the tank. I've had the pressure in the fuel pump checked and it was within normal range although on the low end. I can wait 30 seconds or 6 hours and eventually it will "fire" and run.

I'm very ignorant about car repair, so I attached a couple pictures showing a "clip" (the gray headed wire at the bottom of the picture that is not attached to anything). My car recently died, I suspect due to a drained battery, and I hadn't noticed this before.
Further info: it's a 92 Chevy Lumina and the battery is underneath the area pictured. I've tried to jump it, but can only get it to crank a couple times before failing.
