Lumina :: 1995 Chevy - Excessive Fuel Tank Pressure / Slight Hissing Periodically

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.

Chevy - Lumina :: 1997 - Low Coolant Light Periodically Flashing

I have a 99 Chevy Lumina. The car periodically flashes the low coolant light. I check it and its fine. I don't know if its related to my recent problem. A couple of days ago, my car wouldn't start. All the lights and stuff come on, but there is no clicking or even trying to start. I kept trying. It wouldn't work. I left it alone to make some phone calls. I messed with it again after a little while and it started. It has been running until today. It started, I got my son to daycare. Then when I tried to start the car to leave, it did the same thing again. I let it sit for a couple of minutes and it started again.

Touareg :: No Light Illuminate After Connecting Trailer Brake

I just installed a Tekonsha Envoy trailer brake. I bought the VW wiring pieces and connected it to the factory under-dash plug. The problem is that when this is connected and the trailer is hooked up the green light should illuminate on the Envoy controller. When I have the trailer hooked up, there are no lights lit and the trailer brake unit just seems dead. This is a brand new Envoy.

Lumina :: Brake Light Will Not Go Off In Dash

I recently replaced a broken brake line on a 99 lumina .I have good brakes and pedal, the fluid level is good, But the BRAKE light (Not abs light) will not go off in the dash.I bled the brakes using the pedal,I dont have any other method.The master cylinder was empty for 8-10 hrs.I'd hate to have to replace the master cylinder instead of something simple and cheaper to get the light to go off.I made sure the parking brake was released also. Not sure if ABS has something to do with it.

Chevrolet - Lumina :: 1995 - Steering Wheel Won't Turn?

Two days ago, I brought my 1995 Chevy Lumina to my repair shop I've been doing business with for years...they replaced an A/C compressor, oil change and flushed the sludge. Now today, this morning, I crank it up and the steering wheel is almost impossible to turn...making it almost impossible to drive and unsafe to attempt. My plan is to call them tomorrow and have them tow it and inspect...another expense. This car has been a fabulous 2nd vehicle with 155K miles on it...I'd like to keep it, but might have to exercise other options if the cost/benefit ratio is out of whack.

Chevrolet - Lumina :: 1995 - Speedometer Pulses With The Turn Signal - Cause?

I have a 1995 Chevrolet Lumina with about 175,000 miles on it. I've noticed in the past few months that the lights seem a bit dimmer, and the turn signal doesn't always work for the rear blinkers. It blinks rapidly in the front, but after a nudge to the turn signal, it slows down and begins to work in the back. Within the past couple of weeks, when the turn signal is on, it causes the speedometer indicator to pulse with the signal.

I took it in for the low lights and the signalling issue, and they said it might be the battery since it wasn't giving at a full charge. That was replaced, and the issues were still there. After that they said it would be an issue of getting into the steering column which would be a couple hundred dollars just to try and find the problem, but they couldn't guarantee that would actually find the problem.

Chevrolet - Lumina :: 1995 - Transmission Malfunction - High RPMS But Barely Moving?

I woke up and drove to a stop sign. When I tried to pull away the transmission raced like crazy, HIGH RPMS! But was barely moving. After about 8-15 mph it would finally catch 2nd gear. I check fluids frequently, and topped it off a few weeks ago, and when I finally got where I was able to stop, I looked and there was no fluid registering. So I put 2 quarts in to fill.... Then started the car and it would not go into any gear completely. I'd just feel a small thump, when I shifted. It will actually drop into gear after a while going straight, but it's stil revving HIGH and it won't completely go into reverse. Weirdest thing, the "Anti-Lock" light came on while all this was happening...

Camry :: 2009 - Brake Lights Don't Illuminate When Press Pedal

I have a 2009 Camry and both brake lights don't illuminate when I press the brake pedal but during night time driving, the red tailights are on indicating the bulbs aren't burnt. The third brake light on the top behind the rear seats does illuminate. By the way my tailights aren't the fancy LED ones just the normal stock bulbs. So what's the problem here? Is it a electrical issue?
