Buick - Century :: 1989 - Engine Crank But Will Not Start
Sep 27, 2013
I have the GM shop manual and I have gone through the flow chart for an engine which cranks but does not start. I have confirmed that there is fuel pressure and spark, but the injectors do not fire when cranking. I have gotten to the final troubleshooting step of disconnecting the crank angle sensor connector, jumping A and B terminals on the connector, and momentarily grounding the jumper with a test light. The injectors fire as confirmed using the GM injector test light (in place of an injector). The flow chart conclusion is that the crank angle sensor is bad or misadjusted or the connector is making a bad connection. I have replaced the sensor twice and adjusted it using the GM adjustment tool. The connector terminals appear clean and undamaged. 1989 Buick Century 3.3 liter ...

My 2004 Buick Century is parked outside, it starts up fine and runs fine every morning and anytime it sits for a period over an hour in any kind of weather including minus 25 degrees. Sometimes when I shut it off for say 15 minutes or half hour and then go to start it again it will crank over fine but not start up. I can try several times, same thing.. But then if I leave it alone for maybe another half hour and try it again it starts and runs fine. also no warning lights etc. It's like something needs to reset itself. What is causing this ?

I bought a well-used 1991 Buick Century for my son in December '12. At that point I put in a battery that was bought brand new just the month before. The car ran fine until a couple weeks ago. He tried to start it but only got a slow crank, like a low battery. I tried to jump start it, with no difference. Since the car was at his school, I asked his auto shop teacher to take a look at it. The teacher tested the battery on two different machines and determined the battery was bad. I returned it to the store I bought it at, where it was tested as working fine. I then swapped the battery from my car for his, and his battery (the one that was tested bad) started my car with no problems while my battery would not start his car. It produced the same slow crank. I talked to the shop teacher again, who pulled the starter and took both the starter and the battery to various auto parts stores. The starter tested good, but the battery was tested bad at 3 shops, and weak at a fourth. So the car is still sitting at the school, and we're at a loss. What might be causing this problem and how can we get his car running again, short of just buying another car?

The car died on me the other day at a stoplight but started up again (It resisted for a sec but then caught). Now it's taking a bit to start and sounds very faint when it finally catches and the turn over is slow. I'm no mechanic but I can replace parts. I'm just wondering if it's the fuel pump or injectors, maybe low fuel pressure. I haven't had a chance to do anything to it. Where to start?

I have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.

I am going to reflush and bleed the coolant even though it seems to be full . i dont think it is disappearing. Is it Possible i have a blown headgasket or intake manifold leak?

2002 Buick century will sometimes not start. Seems to correlate with warmer weather and happens after long drives. I try to restart within 10 minutes of turning off and it will start and then in a few seconds the car shakes and the engine dies. I can restart multiple times, but it will always die in a couple of seconds. If I wait an hour and retry, no problem. Once someone banged on the gas tank and that solved it. Mechanic cannot diagnose problem unless it dies while he is there. Should I replace the fuel pump or could it be something else?

Most of the time it has no problem what-so-ever, but once in a while it just doesn't start. It will turn over and over but that's it. Most of the time if I just let it sit for a few minutes (5-20) it will start right up no problem, but I've noticed when it does it often revs up as if I had my foot on the gas. (that took me a while to realize since I often touch the gas anyway.) Once it's running it runs great. The idle settles down to normal after a few seconds and the car runs as if there was no issue. It does this randomly.
I can drive it for days or hours with no problem, and then suddenly it just decides to leave me stranded. Usually i wait and it gets me home, but a couple times it didn't. I've drained the battery twice on two different occasions months apart trying it, and waiting and trying it. Both times with barely enough juice the following day to turn it over, it fired right up, rev'd the engine, then ran fine. I don't think it's an issue with fuel because on one occasion while trying to start it I laid into the peddle until I could smell gas under the hood- and it never has issue while running, only on start-up.
So far the only thing I've done is replace the spark plugs- it runs better now, but doesn't start any differently.

I have a 1987 Buick custom 3.8L that will not run or start with the EGR valve connected to the evr selenoid. How can I verify if it is the EGR valve or the vacuum solenoid? When I connect the egr to the vacuum solenoid the valve opens all the way up and the engine stalls.

When damp or foggy, my 1990 Buick Century 3.3 will either not start or start and idle rough. Spraying WD-40 on coil packs and wires work. I tried click and clack's method of misting water on the 3 coil packs and wires when idling, and got arching on middle coil, # 2 wire to top of coil pack. Do I need to replace that coil, or just the spark plug wires? The slight mist of water on that middle coil stalled the engine, and it would restart after WD- 40 was sprayed on the coils/ wires.

I have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?

[URL] I even pulled the same P0170 code. And what I need to do before I spend a boatload of money and wind up sleeping in my car instead of driving it to work or lack therof is to start a troubleshooting list starting from where Sabot's update left off, i dont even know where the vacuum line is that he mentions and if i sprayed carb cleaner on it would i get a jump in engine RPM or a stall as a test?
What I have done: Cleaned MAF sensor, changed fuel filter.
What I have not done: Checked all vacuum lines, Tested fuel pressure, Tested for compression issues due to blown head gasket.
there is also a puffing noise coming from the exhaust side of the engine, im gonna grab a bottle of baby powder this afternoon and test for air leaks, i dont believe it is a misfire...

I have a 2000 Buick Century and i just recently had the fuel pump replaced because it was totally shot. Everything was fine except i realized when i started it sometimes it would crank really slowly, i thought it was the battery because the one i had in there was like 4 years old. One day it just straight up wouldn't start in a Public parking lot so i bought a new battery and it still wouldn't start. Every time i try to start it, it makes one click then a weird electric swirling sound, but wont crank at all. My buddy who has a lot of experience with cars thinks its the starter. We tried banging on it but no luck. How to confirm if this is the starter?

Last month I changed the oil and filter in my 1992 Buick Century with 264000 miles. I used a name brand (Citco) of the correct oil, 10W-30, API Service SN. I bought the oil on sale at a local supermarket. Now, I hear a loud tapping sound from the engine, especially when it's cold. It dosen't sound as loud after warm-up. The tapping increases in frequency when I rev up the engine. I don't intend to keep this old car much longer, but is this problem an immediate concern? Could it be a valve problem? Could it Could I have bought some bad oil with a conterfeit label? Other than this noise, the car runs okay.

F-250, 1989, 460. Until the truck set through 2 weeks of 90+ weather it started just fine. This morning it would not start. Plenty of cranking power, seems to fire then nothing. I can keep on cranking. I am not a mechanic and will have to get a tow to a shop.

Buick Century 1987 - 2.8L
Sending unit measures: Empty 9 ohm - Full 88 ohm
Fuel pump working while engine is running or key switch in ON position (working properly).
Issue: Fuel needle fluctuates while car is in movement and the engine stops when the car is going downhill and suddenly is braked (half tank), Is normal this behaviour in this car? Is this car equipped with a 'anti-slosh module'? if yes, where it is located?

I had this problem a few times in the past. Sometimes my 1992 Buick Century will shut off for no apparent reason while idling. When I restart it, the engine will race for a few seconds before slowing down to normal idle speed. Could this be caused by a glitch in the car's computer?

I have a 1989 Buick LaSabre that is having some problems and no mechanic seems to be able to figure it out. After 4 computer items totally $1,800.00 since March, the same problem started again yesterday. I am driving through the hills to town and the dashboard lights all come on and my engine cuts out. I stop, put in park and restart and take off again. As soon as I am on the highway, car runs fine. It has something to do with the fuel system I believe because once it cuts out the car smells like lots of gas but after it starts back up (and it does every time) the smell goes away.
