Stalling - Gasoline - Pump - Chevrolet - Noises - Lumina :: 1997 - Loud Humming Noise?
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????
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.

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.

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.

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.

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.
View 10 RepliesLumina :: 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.
Chevrolet - Trailblazerext :: 2003 Chevy Misfiring / Spitting And Sputtering
My trailblazer started with the spitting and sputtering (misfiring) last week. Over 100,000 miles on it, ya, in need of a tune up. So for obvious reasons new spark plugs seemed to be the logical choice. If it wasn't the problem, it can't hurt to change them. Truck's SES light did not come on, but truck was running pretty crappy, more when it was cold than hot, but definetely a loss of power. There is also a slight exhaust leak starting, where abouts right now I haven't pinpointed, deaf in one ear so it's hard to tell where it is coming from.
So I had my brother in law install the new spark plugs. We took the old ones out and 4 and 5 cylinder plugs had oil on them. Ah great, valve cover gasket and the gaskets the spark plugs sit on (don't ask me, not a mechanic lol) need to be changed. Started with just the plugs for now. Started truck up, still had a bit of vibration on idle, like it would from an exhaust leak, but still didn't seem right . But an even more noticable loss of power when driving, truck doesn't seem to want to get above forty.
Now my SES light is flashing almost consistently unless I'm stopped (idled). It almost feels like the cat is clogged. Did smell a heavier than normal gas smell when changing out the plugs. I know that the flashing SES almost certainly means a misfire. But why would it all of a sudden come on after changing the plugs? Tomorrow I am going to my friends garage who has the scanner tool (not just the one that reads codes) to see if it is a bad coil pack and to see if there is a specific cylinder that is misfiring.
But there is something about that exhaust leak that is leading me to believe it is the culprit of my problems. Leak came first, then the misfiring. Could the cat be clogged, which blew a hole in the exhaust and cause a misfire? And the new plugs just made the misfiring worse to cause the SES light to come on? Is there anything else I should check besides a faulty coil pack and compression check (even though I should have done that when I changed the plugs, but live and learn).

View 1 RepliesGolf IV / Jetta IV :: CEL On / Misfire And Smell Of Gasoline
I just recently picked up a 2000 Jetta VR6. its 173k miles on it and has few issues with it.
The Background. The car had a check engine light on and when i bought it I was told it was just an o2 sensor and i trusted him cuz i knew the guy (sorta). Bad move on my part, but not terrible. After I bought the car, i took it to autozone to just get the codes and be sure. It came up with a P1116 - o2 sensor heater circuit open on bank 1 (expected), and I also got a P0302 - misfire cylinder 2 (dafuq?). The misfire surprised me cuz it did not feel like it was misfiring whatsoever and it did not have flashing CEL.
After driving the car for a few days, I have noticed a few things that make me believe that it is either a faulty injector or seal.
1. The misfire, but not significant misfire. The only time I can tell any difference on how the car performs is when its at idle, it tends to not idle completely steady and vibrates a little more than what an engine should. Other than that, the car pulls great and not any issues.
2. The smell of gasoline is prevalent. It takes about 30 seconds before it just plain out reeks. And if you pop the hood and stick your nose right next to cylinder 2, you probably get high off the fumes (if that's possible). I am sure its coming from somewhere under the plenum because it was leaking some type of liquid that I had initially thought was just oil but I really think its gasoline.

I have a 2006 Chevy Cobalt... I can smell gasoline ONLY when I turn the heater or a/c on. I have taken the car to TWO different auto shops and no one knows WHAT is causing this. The check engine light came on recently after a radiator flush and the first auto shop said it was a thermostat switch and bring it back the next day. I was leery of this and went to the second auto shop who told me they never heard of a thermostat switch and to bring it back whenever the check engine light comes on again. Meantime, I will not turn on the heat or air because the gas smell gives me a headache. What this could be?
