Buick - Regal :: 1991 - At Start Up Stall While Cold?

1991 Buick Regal, 3800 V6

As the title says, when I start the engine cold I get a slight puttering and drop in RPMs followed by the engine revving itself to about 1100 for a few seconds and then normalizing at 600. It has only actually stalled out a few times. This does not happen once the engine is near operating temperature.

Now, I did not notice this issue prior to doing some maintenance on the vehicle (radiator replacement and transmission service) and I've read that this can be caused by a faulty coolant sensor. Possible?

Battery is new.

Also, when I say cold start I mean summer temps here in Michigan. So it's happening anywhere from 50 to 90 degrees F.

Buick - Regal :: 1991 - All Four Tires Losing Air

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?

Buick - Regal :: 1995 V6 Won't Start When Hot After 3rd Or 4th Stop

1995 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.

Regal :: 96 Buick V6 3.8L Refused To Start / Radiator Gap Is Very Hard

I have a 96 Buick regal v6 3.8L. It ran good. Started from last winter, it started to act up. In the morning, 98% OF the first attempt to start the car failed: it started but died in a few seconds, but the 2nd attempt always got it start. One month ago, I drove it for 1.5 hours, and parked there for 15 minutes, could not get it started, opened up the hood, waited for 15 minutes, it started. Then I drove it to a auto shop, they replaced the starter. One five days later, I could not started it again after 1.3 hour driving and parked for 20 minutes. Wait for 15 minutes, it started again. The odd is that when it refused to start, the radiator gap is very hard (but not over heated yet), after started it and drove for 30 minutes or so, I feel the gap is cooler than when it would not start.

I drove it back to the shop, they could not any problem. Drove it back. three day later, it stalled when driving. I didn't realize the stall until I need to turn: lost steering and brake power, then notice that the whole dash board doesn't have any light on. Since the car shut it off only after half mile driving, it doesn't looks like heat related (It was on the mountain, it was about 70 F). Then I sent the car to a different shop.

At the shop, they took off the ignition model and tested it good, and put it back. Since then, they started the car several times per day. Finally, on one day, the car shut itself off after running for 2 hours, and they could not start it. However, they checked and didn't find any code was set (they said because service engine light was not on). The shop have been trying to start the car several times per day for 10 days they didn't have another failure. I am not sure what to do with the car. I read posts here, and have the shop checked short circuit, ground fault, fuel wiring harness, catalytic converter, they didn't find anything, and they said that fuel pump seems ok.

I plan to replace crank sensor, fuel filter, and fuel regulator sensor and use the car for work commute (2 miles). what should be done on the car (since it is old car with 120K on it, I don't want to spend more than $500 dollar on it unless I am sure the problem can be fixed).

Regal :: 94 Buick Turns Off While Driving And May Or May Not Start / Voltage Fluctuates

Cars turns off while driving and may or may not start. The voltage fluctuates and dims the lights and such. Now it wont start.

The battery is good. The alternator is good. I put a new computer in it. I don't know what else to do.

On top of this awesomeness, I found this relay/sensor that seems to go nowhere (picture below). There is also a second something or another that you can see in the bottom right quarter (red wire grey attachment underneath cruise control module next to that bundle of wires) that seems to go nowhere. I didn't unplug these.

Buick - Regal :: 1996 3.8 Won't Start / Can't Hear The Pump Running - No Spark

I 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.

Buick - Regal :: 1993 - Intermittent Hard Start / Idles Roughly

1993 Buick Regal 3.1l V6 Multiport injection

Problem: The care currently has a hard start, and a fluctuating idle. I bought the car a year and a half ago it still has low miles about 94,000. The care used to start fine but had a fluctuating idle in the range of 750 to 2500 rpm. My brother who is a mechanic and doesn’t live near, do all the gaskets when he visited. Then the idle fluctuation dropped to 750 to 1000rpm, when the car rpms fluctuate there is a whirring sound I can hear from the cab, like a pump or pull system. On occasion there is a vibration as well but it is inconstant and irregular. Fuel pressure seems to fluctuate as well. If the car will not start I give it a little gas and it will run fine after a minute or two, but then the idle starts to fluctuate.

No fuse issues I can tell and relays seem to be fine.Checked for lose wiring connections found, none. I have replaced:

- Hoses and gaskets
- Starter motor
- Battery
- Fuel Pressure regulator
- Fuel Filter
- Spark plugs and wires
- TPS
- Idle Air control Valve
- Crank shaft sensor
- PCV.

Right now I’m thinking it could be the fuel pump (a nightmare to change on this car), a fuel injector failing, and the ignition switch.

Buick - Regal :: Rough Idle / Misfire On Cold Start - Leaking Fuel Injector(s)

1991 Buick Regal, 3800 V6

Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.

So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?

I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.

And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.

Volvo :: What Causes 1991 Turbo 740 To Run / Not Start / Run Again

I recently purchased a 1991 Volvo Turbo 740 with 186,000 miles on it. It runs perfect for a few days and then when parked will not start. Attempt to start 1/2 hour later it starts and runs perfect again. It has done that for several days now. I have driven it to locations approximately 40 miles round trip with frequent stops for a period of time and then start up again. This AM it started up perfect as I moved it from a driveway to part in front of my house on the street. Several hours later I went to start it but it would not start. 1/2 hour later I decided to try one more time before calling the tow truck to take to a mechanics and it started up perfect again. I drove it to the library and bank later and ran perfect after the two stops. This is driving me nuts since I had taken it to a mechanic when it did this Monday and it ran great at the mechanics and he could not determine what was wrong. He told me WHEN it stops again to have it towed in and he could determine at that time when it was not running.

Celica :: 1991 Will Only Push Start

I have a 1991 celica that I can not get to start. The car has the 3sfe 2.0 in it that I think came out of an 89 celica. We have put a new starter on this car, alternator, plugs, wires and distributor cap, battery and more onto this car. The car however will push start. When you turn the key everything comes on and it clicks. Nothing else happens.

Ford - Taurus :: 1991 V6 Keeps Trying To Start

I have a 1991 Ford Taurus 3.0 V6 and when we go to start it, the thing tries to keep starting(turning over). Even after the key is turned off and removed. The starter just keeps going. Have to remove positive battery cable to stop it. While it was doing that the neg wire started to smoke. If I just touch the battery cable back on it tries to start. If it sits for a bit we can hook it back up and it works ok. I just had the starter and the starter solenoid replaced.

Ford - Explorer :: 1991 XLT Won't Start - CEL Is On

1991 Ford Explorer XLT, 4X4, 4.0L push-rod motor, 315,000K

Problem Part 1: Excessive fuel consumption

Codes for O2 sensor, system lean, some black smoke, unburnt fuel smell, some slight hesitation when accelerating from a stop

I replaced the 02 sensor, replaced the IAC, cleaned the MAF, replaced the coil pack, replaced the plugs, replaced the plug wires, replaced fuel filter, replaced air cleaner, replaced the PVC valve changed brand of fuel, checked tires and "brake binding" - NOTHING. Truck ran "fine" other than excessive fuel consumption. I decided to replace the fuel pressure regulator and before I could get to the parts store we have...

Problem Part 2:

Truck begins to lope along like there is one bad cylinder. It sometimes "fixes" then comes back (all this over a period of 3 days).

Day 4 it's dead - no start.

The motor cranks, the fuel pump "pumps" 3-5 secs KOEO fuel line is clear, return line is clear, filter is clear. There is fuel at the Schrader valve (do not know pressures) and the electrical system seems OK (sparks to all 6cyl). I believe the crank position indicator is OK because the CEL is on KOEO but goes out when cranking. I have no codes because I needed to remove the battery to re-charge. Fuel pump fuse is OK.

Only other information that may (or may not) be relevant is that lately it is slow to heat up. It does not come off "cold" (for the last 4 days). Maybe it's the thermostat or temperature sending unit? Maybe it's because its -30C here. It heats up fine if I block the airflow across the radiator (the old carboard solution).

I have not checked the relay. Where this unit is on the 1991? Don't say fuel pump.
