I have a Buick regal 1996 v6 3.8l . SO my car tends to over heat really fast with the reservoir still nearly full of coolant also my fans also turn on really late.. Ive came down to the conclusion that it might be the temperature sensor idk whatelse to do. Ive changed the thermostat about a month ago.
View 14 RepliesHow long does it take to change a crankshaft sensor on a 96 Buick regal custom 3.8L anything else I should change while changing that?
View 1 RepliesMy 96 Buick Regal acts like it is out of gas after driving for about 10 min. Takes awhile to start, then runs rough if at all. After it sits, it runs fine again for about 10 min. I changed fuel filter, fuel pressure sensor and fuel pressure regulator.
View 4 RepliesI can't get my passenger door open. The car has electric door locks, they are working, the door does have a key, it works, both handles seem ok, but the door does not unlatch. I can't get the inside panel off since it is closed. I'm considering trying pop a lock???
View 1 RepliesI own a 1996 Buick Regal with 132k miles on it, 3.1L six cylinder. The other day I was doing some general maintenance and noticed that the exhaust smelled like sulfur (rotten eggs). Now, I am loosely familiar with the causes of such a thing but not well enough to diagnose it properly the first time. The car has been idling rough since I got it (almost a year ago now), I have a feeling that it could be the O2 sensor causing the rough idle and the sulfur smell but I am not completely sure. I should have one of those fancy three-part injector cleaners done?
View 6 RepliesI have a 96 buick regal thats been giving me problems for over a year now. it from time to time acted like it was out of gas even though it might have a half a tank. Turns over fine but won't start after it sits for a couple of days then it starts fine. Last summer my son replaced the fuel pump after doing a pressure test and getting a low reading. No more problems until jan then it started doing it again. Well about 3 months ago it wouldn't start so I had my wife turn the key on and I stuck my ear in the fuel fill tube and I could not hear the fuel pump.
I checked the fuel pump relay by putting my finger on top of it and I can feel it click when the key is turned on. Also the air relay next to it is the same so I switched them no change so I replaced the fuel pump again and also the sending unit so every thing in the tank is new. Car still won't start can't hear the pump running and i checked for spark no spark now. My other son has been saying he thinks its the ecm so I just put a reflashed used ecm in. Did the security relearn procedure still nothing. whats next? Somebody told me check the cam and crank sensors and wiring. I also replaced all the ignition coils last summer.
I have a 96 buick regal custom. I tried to program a keyless fob through the trunk it dint work and now my lock buttons on the inside of my car don't work but yet they automatically lock and unlock when I turn on the car when I go into and out of park gear.
View 3 RepliesI have a 97 Buick Regal with turn signal issues. The left side will not flash but stays lit and the right side flashes fast. I have the problem isolated to the Daytime Running Light Module. (replaced turn signal stalk, flasher and bulbs). I ran a jumper wire bypassing the module and everything works as it should. Do I need to replace this module, or can I simply bypass it without it messing anything else up. I don't want my horn going off when I change the station on the radio.
View 1 RepliesOk, my 1996 Buick Regal is acting up. I got a CEL, which was a P0306 (Cylinder #6 misfire), took the car to my shop, and they diagnosed as a faulty Ignition Control Module. Fast Forward, a day later, the car now has a hard start problem and throwing the same code, plus a P0102 Mass Airflow Sensor.
So my questions are:
1) Could a faulty ICM cause a single cylinder misfire, did they just replaced a random part? I would think a bad ICM would a multiple misfire considering on this car each coil controls 2 cylinders.
2) Are the two codes related? ie fix one, and the other would go away? or are they separate issues?
3) What could be wrong with my car?
This mechanic has been in my family for years, however, I'm not very pleased that a day later, my car seems to have more problems than before. Am I being too harsh?
About the Car: It has 101,00 miles on it. I haven't own this car for long (less than a month). I bought it pretty cheap to do some grocery shopping with. I have no plans to drive it more than 10 miles in a trip. I have a bicycle with a trailer, but there are days in the winter when the weather says, "No" to bicycling. I had the fuel pump and filter replaced at a shop when it wouldn't start a couple weeks ago. They said the fuel pressure was low, and it needed to be replaced. It was fine for a little while, but then it wouldn't start for the past three days now. No cranking at all. I can turn on the radio and roll windows up and down, though. I do remember seeing a Check Engine, Battery symbol sign, and a couple other lights off-hand. I'm at work right now.. so I'll have to go home to see if the Security light also was there, too.
Also! I did find an electrical line that did not go anywhere... not sure if that has anything to do with the fact that there is no window washer fluid tank (wipers do work).
After reading a little about other Buicks in the forum not cranking, I will definitely try the Security Light issue after I get home from work.
I have a 1999 Buick Regal GS with a supercharged 3.8 liter engine and 161,000 miles. I bought the car off of my uncle and he said he would have to change plug wires every month to month and a half because it would start missing so bad. When I first drove the car it would quit on me at red lights and in parking lots, it only seemed to do it at low idle speeds. I live on a hill with a blacktop road and I had to give it a lot of gas just to pull the hill it was missing so bad. The plug wire had a lifetime warranty on them so I replaced them and it stopped quitting on me but I still had a bad miss at random but not as bad it would just be like hard jerks. I added sea foam fuel injection cleaner and had the fuel filter replaced. The mechanic checked the spark plugs and he said they were like new AC Delco. I also cleaned the MAF Sensor (the mechanic told me to and how) because the engine did not run steady at idle and it seemed to work that, but not the miss. Could my problem be the plug wires? They are carquest brand 7mm wires.
View 6 RepliesMy 1995 Buick Regal seems to loose gas pressure. Have had several repairs done, fuel pump, fuel pressure regulator, fuel filter and nothing seems to work. It seems that the repair shops are guessing at the problem. Sometimes it even stalls out completely but usually starts back up.
View 2 RepliesHere over the last week or so I've noticed my car start to have a bumpy ride around 35-42 ish mph, and around 65-70 ish mph. It feels worse probably around that 40 range, and seems to be even more pronounced during acceleration. It's not a super high frequency or anything, maybe just a couple hundred HZ. I have been driving it considerably more over the last month with my new job (around 140 miles a day, mostly highway/interstate driving). I've got an oil change/ fluids checked about 3 weeks ago or so.
2000 buick regal ls ......
I just picked up a 1991 Buick Regal for a good deal, but already the repair costs to get this thing up to speed are mounting :
Right now I'm dealing with all four tires losing pressure. The 24 year old car still has its original wheels (15 inch aluminum) and I'm assuming that they are losing pressure at the seal. The tires are only about a year old and the stems look okay, so do you think I'm on the right track?
There is one strange part to all of this: The vehicle with its equipped tires is rated at 30 PSI and if I fill them to 30 they are all down about five pounds within a few hours or after a drive. However, they do not lose more than or much more than 5 PSI. The front tires lose more air and lose it faster, but the lowest I've seen them is 23. Is only losing a few pounds of air and not going flat evidence of a seal leak or am I in the twilight zone?
I have a 2001 buick regal with the odometer lights out. How do I fix this? Do I have to take the dash off to get to the light?
View 3 RepliesI have a 2000 Regal LS that has no heat. The cooling system is full of water. The heater hoses are warm. The fan blow lots of air and the speeds can be changed by the heater controls. The heater controls light up and you can change the fan speeds. My guess is the control doors are not working. What should I check to figure out what is wrong.
View 4 Repliesmy 1995 buick regal does not have a spark, and I have had 2 mechanics look at it. The sereptine belt broke while I was driving, I believe it was because the water pump was bad and locked up. the belt got wrapped up in the crank pulley and I removed it. The AC has not worked in a really long time so I do not think that it is that pulley. It is not getting a spark. I have replaced the water pump, and the car sounds like it wants to start but it is getting no spark to it. I have had the crank sensor tested and the coil something. none of those seems to be the problem. some one suggested that it is the computer brain. I suggested that it was the timing. Though I do not really know. the battery is good so i know it is not that. and it has fuel. and i know that the engine is getting fuel. I know that the spark plugs are not getting spark (tested with a screwdriver in the socket on metal) So what is wrong with it.
View 12 Replies1995 Buick Regal, 128k miles, 3.8L V-6.Problem: When running errands around town, car will temporarily not start after 3rd or 4th stop. Vehicle cranks, has spark, has fuel pressure at fuel manifold. No codes on computer (Wish it was a '96). Car will start normally after cooling off (generally takes at least 45 minutes). No problem driving to work, parking all day, driving home. Have not tried long distance driving since problem arose, due to concern about being stuck for awhile far from home. Have determined at EGR valve is NOT a part of problem.
Sample situation: Drove 5 miles to town. Shopped for 15 minutes. Drove 2 miles further with 5 minute stop. Drove another 2 miles with 5 minute stop. Drove 1 more mile and stopped for 30-40 minutes. Car would not start. Cranks strongly, has spark and fuel pressure (don't know if fuel getting to injectors). Still would not start 30 minutes later. Left car for several hours. Started promptly and ran normally on return. Weather conditions - 90 F, low humidity. Problem has been occurring for several months. No computer codes to dive guidance.
My Regal has no dash lights, I checked the 7.5 amp fuse inside car and it is good.
View 11 RepliesI have a 1995 Buick Regal, with a 3.8L engine. When I start the car sometimes it rough idles and I have to give it a lot of gas and then it runs fine. This is completely random. Sometimes it runs just a little rough, other times really rough. The rough idling when starting the car happens about 1 out of 25 times. Sometimes when this happens I get a check engine light, most of the time not. When I am driving around I also will randomly get a check engine light, but I can't tell anything common to it. It has come on while braking, while coasting with foot off the gas and brake, normal city driving, highway driving. Also my CEL always turns off when I turn off the car and doesn't come back when I restart the car. Always.
I haven't been able to figure out what is wrong and since my car is transition OBD1 to OBD2 I can't use a OBD2 code scanner (it is an OBD1 port), nor will shorting the pins in my OBD1 type port give me codes. Being this the case I took it to a local mechanic and they scanned the computer and said they got 16 error codes. They reset the codes but couldn't get the CEL to come back on. I took it drove it for a couple of days the light came back on so I took it back to the shop and they got 18 codes out of it, but they were mostly different, with some of them giving the opposite readings of before (O2 sensor high one time, then low the next check). They said they didn't know what was going on but wanted 3-4 hours to diagnose the PCM (Powertrain control module) and would probably replace the PCM (~500 on top of the diagnostic fee). That was a bit much for me, so I took the car back.
The things I have checked are fuel pressure (seems fine at idle and revving the car in park)Vacuum is 19 and when I rev quick it drops to zero or so then up to 25 and slowly goes back to 19 (I think that means vacuum is ok). I put the gauge in the O2 sensor before the CAT and I didn't read any pressure, so I think the CAT is ok.I put on a new fuel pressure regulator, and a new fuel filter. I got the same PCM at a Pick-n-pull place and put it is my car 3 days ago. Yesterday I got a check engine light while driving again. The mechanic will charge me to check the codes, but I think it is just doing the same thing as always. I am sort of at a loss as what to do. I though it I was to dive around with a scanner hooked up and the light went on then I could see what the sensors were doing when all the trouble codes fire. I was looking at the Actron CP9190, but it doesn't log the data stream for OBD1 cars, only for OBD2.
1995 Buick Regal 3.8L Series 1
This is my first car and I got it at 100k and I am up to 162k. She has been good to me. A week ago I noticed that my car was shuddering and having real issues getting up to 55 (misfire). These were intermittent and seemed to go away when I put new sparks in it.
Tonight I started it and heard a good sounding pop. The car would not idle right at all. Press the gas, up to 3k rpm, and let go ... stall. I got under the hood, heard a strange sucking noise, with some cell phone light found out the vacuum hose fell off??? Put that sucker back on. Idled way better. Driveable (the brakes worked again).
Took a look around the car and noticed that some smoke was coming out of the exhaust. Not a lot, but I havent really seen exhaust from it before. My buddy followed me home and said he could smell me the entire way.
It is was dark and I lifted the hood and noticed moisture all over. I mean everywhere. Spark wires, airbox, frame, and etc... I have been looking through my books and then online. I cant find anything. What I can be looking at for a root cause? What is messed up with this car?
