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.

Lumina :: 1999 Chevy Misfiring - Gasoline Smell

I have a 1999 chevy lumina 3.1 with only 317,000 mi. and running strong. I had put new plugs,and wires about 6 weeks ago. The other day it started misfiring and I could smell the gasoline. I checked the tail pipe and it showed black smoke. In addition I put a piece of paper on the tail pipe and I could feel the misfiring with a consistent rhythm. I notice that it is running flooded(like if a fuel injector is not working correctly.) I cleaned the throttle body, checked all the coils and the spark plugs and they are good. It does not show any check engine light on. What could it be?

Lumina :: 92 Chevy Euro Has Spark But No Injector Pulse

Was called today to look at a car that wont start its a 92 Chevy lumina euro with the 3.1 v6 automatic 4 door. The car has a new crank sensor recently installed ran well for a while and now has no injector pulse. Checked for spark its good. sprayed starting fluid in the intake and it fired for a second acted like it wanted to run and then died. Checked for fuel at Schroeder valve it has fuel there I don't have a fuel pressure gauge but it sprayed pretty good. I'm not real good with electrical but thought maybe the ICM under the coil packs could be bad I have one off a running engine on my shelf but wanted to see what other people had to say first.

Lumina :: 1990 Chevy Just Stopped Running While Driving At About 55 Mph

So about 3 weeks ago, I was driving down the road at about 55 mph, on cruise control, when my car just started slowing down. I looked to see all of my dashboards lights on and I realized my car was not running. I shifted into neutral and the car started right up again, but when I pushed on the gas it just kind of stuttered and shuttered before dying again. When I came to a stop, again the car started right up, but repeated the shuttering and hesitating when I pushed on the gas and tried to get going again.

So, I repeated, but this time i just pushed very gently on the gas, getting up to between 5-10 mph before the car died again. At this point, it just stopped running completely. The engine would turn over, but would not keep running. When I got it into the shop, the mechanic said they put a fuel pressure gauge on there and the readings indicated that there was plenty of pressure, no problems the fuel pump or lines.

After further research, the mechanic said he thought it was an electrical problem, that it could be the crankshaft sensor or the ignition switch module, but he just did not really know for sure. I had him replace the crankshaft sensor, since it was the cheaper part, and it didn't fix the problem. So now I am just kind of stuck on what to do here.

Lumina :: 1994 Chevy 3.1 Stalls When Put In Gear While Engine Warm

A week ago, driving home, the tech started to drop quickly to zero then recover, like the ignition was turned off and then back on. I was able to make it home. The car was due a tune up. I replaced the crank position sensor (OEM), replaced sparkplugs (Autolite Iridium), air filter, fuel filter, no luck. I ohmed the coil packs, secondary resistance showed good, replaced the ignition control module (aftermarket). After this, engine would stall after it was at temp, could restart, once put in gear it would stall, but I could go in reverse and drive home backwards.

Reinstalled original OEM ignition control module. Towed to GM Dealership, mechanic said fuel pump was bad, ignition wires needed replaced, one injector ohmed bad. I took car home, replaced fuel pump (OEM), ignition wires (OEM), no luck. Removed plenum, found pcv valve clogged, and hose kinked, replaced both, ohmed all 6 injectors, 5 injectors read 12.3 ohms, 1 injector was 11.6. Replaced all 6 injectors, (Napa), plenum gasket, still same problem.

GM dealership said computer said no data, they though perhaps ignition control module was bad, but I don't think so. I hooked up my Actron shorting plug, reads code 12 which means no faults, no other codes. I noticed EGR valve has a lot of carbon in the hole, thought about changing it, but I'm really not sure where to go now. The car is a 1994 Chevy Lumina with 230,000 miles, spent about $500 the last week doing brakes, and trying to fix this engine. Where to go from here.

Lumina :: 92 Chevy 3.1 Crank But No Start - Car Started To Stall Sputter

This car started to stall sputter. I replaced the ignition module and it worked for while then nothing at all but still cranks. I checked all of the fuses and every thing was working. What I have found and i think this was the whole problem. The wiring harness that goes from the ignition module to the crank sensor, the wires were twisted and frayed and most likely grounding out on the frame and making the computer to shut down. So far after replacing the wires it started right up. Have not had a chance to take it for a test run to re learn the computer because my brake line busted.

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.

Chevy - Lumina :: 1997 Sporadically Stopped While Driving Slowly Or Standing Still

Last winter, my car sporadically stopped while I was driving slowly or while I was standing still. I usually turned the engine off and restarted it right away without a problem. It happened a few times and then it stopped. This winter, it began again - frequently. I realize now that it only happens during the cold months.

Camry 2012+ :: Clicking Noise While Reversing And Braking Randomly

The other day I reversed into a parking spot, and noticed as I was braking and reversing a loud clicking sound is coming from what seems the front driver side engine area. Every time I would brake it would click. I read of this problem on the Gen 6 and apparently there is a TSB for the front Rotors needing to me re-machined? The funny thing is this only happens when I reverse and brake, but it only happens randomly.

Elantra XD (2001-06) :: Clicking / Popping Noise When Reversing, Turning The Wheel And Braking

Okay I have a 2006 Hyundai Elantra with 56,000 miles. Whenever I have been driving for a while in town and and the car is heated up, I get a clicking/popping noise coming from the front end whenever I reverse, turn the wheel, and then brake.

I've been testing it more but it won't always click or pop when i turn the wheel, but when I push the pedal down to stop it clicks and pops a lot. And then as I turn the wheel back without being on the brake pedal it'll click a little bit more.

Normally this would sound like a suspension problem but the fact that I have to push the pedal down to "activate" the sound has me baffled. And the weird thing is, is sometimes when I'm turning into a parking spot at low speeds it will click just a little bit..

It almost feels like the brake lines are getting tangled up and making sounds. I know that's not the case but I'm trying to describe the sound. It's not the normal pop you would get when a tie rod is going out. It doesn't really sound like its metal on metal. And it doesn't constantly click while reversing or turning like it would if it were the CV axle.

The car stops just fine though.. I'd even say the brakes are pretty touchy. The other issue I have with brake sounds is coming from the back. When I'm slowing down ... at around 15 mph it will click in the back every rotation. It has to be coming from the drum brakes. That doesn't concern me so much as it probably is time for new pads or something in the hardware needs tweaking.

Lumina :: 1990 - Accelerates Slowly Dies In Reverse

I have a 1990 chevy lumina 2.5 L 4 cyl. 100,000 miles....The car recently started chugging while in drive and will not accelerate correctly, when I do get it to 55 mph there's still chugging, Ive replaced the fuel filter, spark plug and wires, fuel system clean, new battery, there is a inch crack in the exhaust manifold on the front of the engine, not sure if that would make me lose power to accelerate, the car idles fine, but chugs when put in drive, and will occasionally die when put in reverse....

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.

Lumina :: 1995 LS 3.1L - Amber ABS And Red Brake Light Periodically Illuminate

1995 Lumina LS 3.1L w/ ~185K mi

A few weeks back, the amber ABS light would periodically illuminate and then became more frequent until it was On every time I used the car. The light only comes on after driving the car forward ~10-20ft. Recently in the past few days, the red brake light also started coming on at the exact same time as the amber ABS light. I can start up the car and idle, backup, and then as soon as I drive forward 10-20ft., both lights simultaneously illuminate, along with the sound of something that is engaging/closing/switching etc. coming from the front driver's side, maybe where the brake module is located. The sound coincides with the illumination of the lights. There is also absolutely no noticeable difference in braking.

I just changed the oil a couple days ago and the fluid level was good and appears to have not moved at all since I flushed the lines ~2.5yrs. ago. I cannot recall if I returned the pistons to the home position back then, but either way I was able to bleed all 4 lines.

What may be causing both lights to illuminate together when the car moves forward in addition to coinciding with a sort of clunking/engaging noise coming from the front driver's side?

If I have to replace the EBCM, then do I need a scan tool?

I already called Module Master and they do not rebuild any GM EBCMs built before 1999. Looks like Rock Auto has some though.

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...

Cavalier :: Vibration When Braking On 1999 Chevy

I have a 99 Chevy Cavalier with the 2.2L OHV engine, and I've been dealing with vibration when braking, especially at highway speeds. I just had it in for service and my mechanic replaced a warped front rotor and said that was the problem. It's better now than it was, but I'm still getting some vibration.
