starter not working

Hello,

Since you have the same problem after replacing the starter, you either got a bad starter or your battery is bad.

This guide can tell whats going on

FYI - Just because all your eletrical work fine doesn't mean your battery is good. If you check you battery with a Volt/Ohm meter it could show full charge (12.60 volts). What the meter doesn't show you is what the CCA (Cold Cranking Amps) are and they are what is needed to turn the engine over. And depending how low they are in some cases jump starting from another vehicle may not work.

I suggest you remove the battery and take to your local parts store for proper testing.

.

a new battery was just put in. I t cranked a couple of times but now it will turn over but will not crank.

Have a helper crank it, while you check for spark at the plugs and injector pulse. Use a gage and check fuel pressure. How long since a tune-up? Any applicable mil codes?

Just to add, cranking is starter motor action. So your saying it cranks good but won't start?

It seems that whenever its rainy or snowy outside or really cold, my car doesnt like to start...It seems that I have to start it every couple hours to make sure it starts and even thats not always guarenteed. I have gotten a jump from some people and it seems that sometimes it we try long enought my jumping it, it will start...I dont think its the battery because it only happensat this time and the only reason the battery dies is because we drain it trying to start the car....please help!!!!

test the battery and if that is not the culprit then try to jump it and test the alternator, I will send you some links that will show you just how you can do it

1990 Buick LaSabre 6-Cyl gas engine. Does not start, sudden onset. Turned key in ignition everything went dead, no lights on dash. Tried charging battery and jump starting but no impact. No electrical power to systems. Was running well up to this point. Noted power came back on, light in truck and ceiling lit, but when I tried to start, when key turned, everything went dead again.

Check the battery and connections if okay-possibilities here could be the starter motor, starter relay, park/neutral switch and ignition switch

Please run down this guide and report back.

My Buick did the same thing.....it was the key whichI replaced and it started right up. It cost me $18.00.

I suspect starter or relay, possibly ignition. I am confused by the "key" being the problem. The key I use turns easily in the ignition, just no responce. And there is no power to any system. Maybe the non-battery end of one both cables is not making good contact. Waiting for warm weather.

my 90 buick LaSabre will not crank once it gets hot.
we replaced the mass air volume control, then the computer said it was the coil pack, we replaced that and then the fuel pump...and still doing the same thing...runs fine while its on , but once you turn if off, it has to sit till it cools down, sometime 3 , 4 or maybe even 6 hrs...any suggestions? ive spent 550 to far!

My 90 did the same thing the water test worked and a new crank sensor fixed it. I worked for a buick dealer for over twenty years.

is there a fuel safety valve on 90 Buick LeSabre?
Hose clamp broke on bottom of radiator and lost all fluid, while on expressway. Car lost power, temp gauge went all the way and after car cooled and fluid was added car now won't turn over.

Are you saying the starter won't even crank? Is the engine siezed? Can you turn the crank pulley or flywheel by hand?

1989 Buick Lesabre 6 cyl Automatic 89000 miles

We have a 1989 buick lesabre. When we go to crank it, it tries to turn over but won't crank. It is not getting no spark to crank. We have tried replacing the ignition coil, the ignition module, and replaced the battery. Just was wondering if you can help us decide what to do next or what it might be... (He has also pulled out the some of the fuses to make sure they haven't blown)...HELP!!!

First I recommend purchasing a service manual for your car. This will provide you with the specs, wiring diagrams and illustrations that would take me a very long time to hunt down for you.

Then, the first thing you need to use is a DVOM to see if there's 12-volts present at the ignition coil pack. If there isn't, trace the wires/connectors until you find out why.

If there is, then you need to see if the Ignition control module is telling your coils to fire. You do this with a test light connected to the "Start/run" terminal, removing the fuel pump relay, and turning the engine over while watching the test light. (This is why you should purchase a service manual for diagrams)

Your control module needs to receive a crank and cam signal in order to tell your coils to fire. So if the module isn't sending a signal to the coils, then on/more of these sensors is bad, the wiring/connectors are bad, or the module itself has failed.

You need to "TEST", then "REPLACE" the components in the ignition system. Playing a guessing game will only cost you money that could've been spent on a mechanic.

All new everything almost, starter, plugs, wires, tires etc. Fuel pump, filter, and relay all new. Ignition cylinder new too. Turns over, will not crank just buzzing noise from somewhere maybe the electronics box under dash. Starts sometimes if I mess with it while key is being turned in the start position while buzzing is happening. I have to kind of slightly push the metal ring around the cylinder will turning key over. Ugh, help! Is the buzzer switch in the steering wheel hub bad?

The buzzing sounds like the starter solenoid reacting to low voltage. I would follow this guide to see if the battery passes the test.

Please let us know what happens.

Cheers, Ken

Jump started my lawn tractor yesterday with the Buick, no problems . Got back into car a few hours later, engaged key absolutley nothing. No clicking no sound at all. Battery is fully charged, can jumper solenoid on starter , starter engages. Checked fuses in car and under hood all appear ok. Disconnected battery to see if that would help, nothing. while under car noticed starter was dirty and oily, worth taking connections apart ? This is driving me crazy, please help.

So you jumped the the starter solenoid to the battery cable on the starter and the starter kicked over?Do you have a multimeter or test light?

i believe this is the model with 2 positive cables on the battery stacked together. it is common for that connection to corrode and cause this. it is the only thing i can think of that relates to what you did.

Roy, THe year on my Lesabre should be 1992 not 1989 sorry for typo.I can get a tester yes. What should I test for. Please get back to me asap driving me nuts. Another thing is when I turn the key to the start position the security light constantly blinks. The security light has been on always for the past six months with no ill effects.Just don't understand why everyhing was fine now nothing.

locksmith told me it is a broken wire on security system, need to replace lock cylinder an wiring.

1988 Buick Lesabre 6 cyl

I thought I had a bad battery. They checked it out and said it had 12 volts but the cranking amps were really low. so i got a brand new one with 1000 cranking amps, put it in, and absolutely nothing! I checked all the fuses in the panel, and all appear fine. I have a problem that I thought may have partially caused the no start one. The shift rod that has a little round end that fits over a nipple would come off on occasion. The shift in the car would just be really loose when this happened, and all I needed to do was open the hood and pop in back on. I tried a tie wire to hold in down, and that worked for a year or so, but then it started popping off the nipple again. Would this have anything to do with it not even making a sound when I turn the ignition key? I mean, the new battery can't be it, and it's installed properly. Of course the lights and everything else are strong. Is there an emergency swith in the trunk or somewhere that I need to reset? Please help! Thank you very much, Ray

Hello, does your vehicle have a theft system? That can cause problems.

If you have an automatic, the neutral switch, gear select switch, whatever they call it, can also cause problems.

The small purple wire at the starter solenoid should be hot with the key in the crank position??

yep, there are 2 very thin wires in the lock cylinder that break and disable the starting system. it requires disassembly of the column to replace the lock cylinder assembly.
you will need a shop for this unless you have steering column expierence.

Roy

I don't know! You're the mechanic not me. I was hoping you would say, yep, just open the trunk and you'll see a switch and yada yada, or, let me know if the shifting rod can casue a misconnection somewhere in the starting system.

Could jump staring my lawn tractor drawing down the battery have caused the security sytem to lockout the ignition ?

Sorry, I can't see your car from here. All I can do is suggest what to test. You have to do the testing.

nope, i think it was have happened even if you did not jump it.

Electrical problem
1983 Buick Lesabre V8 Two Wheel Drive Automatic

my battery is reading around 12v. i had my altenator tested at autozone. they told me it was good? when i try to start the car, i hear the starter engage and if i hold it in start the starter tires down. no crank. could this be an ignition switch. a few days ago the isturment cluster was blowing fuses then popped now wont come on. the battery lights been on also. could all these problems be realated?

welcome to the forum. I'd have to make sure he battery has a full charge and the connections are good. With everything turned off, use digital voltmeter across posts. The generic spec for a full charge is 12.6 volts. Take a second reading across battery posts, engine running, if you can get it started, the second reading should be higher than the first, if the charging system is working. The charging system needs to be checked on the vehicle. The alternator my test fine at the store,but, if there is a problem with wiring circuits to or from the alternator, it won't charge on the vehicle.

MY CAR WANT CRANK IT WANT TURN OVER ITS LEAKING OIL TIME U PUT SOME OIL IN IT SOME DAYS LATER ALL THE OIL IS OUT OF THE CAR AND ITS ALSO 26 YRS OLD WHAT COULD BE THE PROBLEM AND THE MOTOR THATS IN IT DOESNT BE LONG TO THE CAR THE MOTOR THATS IN IT IS A 350 MOTOR FROM A 85 OR 86 BUICK I DONT HAVE A PICTURE OF MY CAR DO U MIND IF I SEND IT IN LATER.

There's several ways the oil can leak out of the engine.

There could be a leak in the oil pan, crankshaft rear manin seal, timing chain cover, valve covers, or even the oil drain plug could be loose.

If your engine is smoking a lot, then it could be leaking into the cylinders of the motor and out of the tail pipe. Though that would use up your oil a lot slower than in a couple days.
