Starter not working

try a security system reset it may be an intermittent problem either with ignition lock or something else in the system. a mechanic should use his scanner on this to see what the problem is. See picture.

This guide can help fix it

Replaced transmission. Pulled motor and all out. Put new transmission in motor etc. All wires plugged in and grounds checked and triple checked. No crank over. Can cross the starter will turn over no run. All fuses checked and triple checked all are good. Battery is in tip top shape. Starter pulled and tested for extra measure tested good. Turn key to "on" lights come on and stay on, security light goes out (PKIII system), security light does after a few minutes with key left on "on" beeps three times and stays on, Did run a relearn process five times no change. Turn to "start" no crank starter fuse relay clicks no run. Ignition relay is eight volts good the same for starter relay. I am at a loss any help would be great.

Update:
plugged in a scan tool and theres no comm to the PCM Or the BCM, testing the pinouts on the PCM will update later.

Please get back to us we are interested to see what it is.

Cheers, Ken

PCM tested bad but was a false bad, Replaced PCM with a exact match no go. Currently its in a shop now still waiting on a answer.

Please let us know what happens

Cheers, Ken

turns out its so stupid, the main wire connector on driver side fender under the hood was backwards. problem solved

Nice work, we are here to help, please use 2CarPros anytime.

why 2001 lesabre wont start. battery,alternator and starter is good.

**No crank at all/nothing/nada when key is engage to starting position

Could be starter relay, clutch switch/park and neutral switch/transmission position switch and ignition switch assuming the battery condition and connections are good. Note:If it doesn't apply disregard.

Initially the heater would not come on....all the control lights indicates it's on...Heater would not work in auto and could not get the fan to come on or outside vent air even. I checked the fuses and could not find anything amiss....this is when the real trouble started. I went to start the car and Nothing. The dash lights come on but the solenoid/starter doesn't even click. I jumped the battery but nothing. The whole heater story may have nothing to do with it but could could a relay be the problem? I called AAA club and they came out....same thing, jump did not help....dead silence. He checked the battery...it's Ok and he did a simple continuity check and it appeared that power was getting as far as the fuse box. Any ideas before I have the car towed to a Dealership? I swapped out the few 10 amp fuses that I initialy touched but still nothing and again maybe it's coincidental.
Thanks,
Dennis

Hi:
Dennis, are you getting power to the starter when the key is in the start position? If you are, it sounds like a bad starter. If you're mot getting power, go to the relay and check it. If no power there, check the ignition switch itself (not the key). The problems may be tied together.

my 2001 buick la sabre won't start, the radio and a/c come on,what could it be?

Most likely battery can you get a jump?

2001 Buick Lesabre 6 cyl Automatic 160000 miles

Hi, I've been driving a second-hand lesabre for a year and a half now and have not really had engine problems, until now. I've had three window motors go out, but that is something I can live with right now. My engine not starting, on the other hand, is something I can't.
I was driving to work today and when I got out, I heard a sound coming from the front. It sounded like a belt turning or something like that. I popped the front open, but didn't see anything wrong. There was a slight burning smell. I tried to start my car, but I turned the key, and it wouldn't even turn over the start. The brake locked up and nothing happened. It's been a little harder to start it recently, but nothing like this. I let the car sit for a bit and came back to look at it. There were no sounds, but when I put the key in to start it, it wouldn't turn and the belt sound came back on. Help, please?

it sounds as if your battery may be dead. If you can jump start it with aset of jumper cables then that may be the case. If you charge your battery and take it to a auto parts they can test it for you. If you have a digital volt meter put on to the positive and the other to the negative and it should read at least 12.40 if it doesn't then the battery maybe bad. If it does then the battery cables should be cleaned and try it again.

I backed it out of my driveway and, having forgot to get soemthing in the house, turned it off. When I tried to start it again, I could hear a click near the key, but lights do not dim and engine does not turn over. Battery was checked but is fine. One person suggested it has something to do with the key or Theft Deterrent system.Any advice?

check your fuse in teh rear fuse box under seat marked ign sw. also the sufe under hood in undrhood fuse box marked pcm/ign also the circuit breakeer marked start. Then check the relay in same box. if all that is good then hit eh starter on the side of body with hammer and if it starts the starter is bad. Also check your battery with a vom and it should read 12.4 volts with nothing on like lights, etc.

My apologies for mistyping, but lights do NOT dim. I will give your suggestions a try.

Any word on this frequentflyer?

Lol-Yea! I fly the redeye

Me too!

When i put the key in the ignition and crank it, the car will turn over but stays on for just a second. its like it is gettin just a little bit of gas. does that sound like a plug problem? It has plenty of gas

Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

After 3 attempts to get the problem fixed w/our personel mechanic, the problem is still happening. He says it is the ignition, and has put in a dummy switch under the dash to start the car with when turning the key don't work. But even the dummy switch has failed to work the last time it refuse to turn over. The battery has been tested-fully charged. Fuses have been checked and a complete overhaul done. If it is the wiring in the console for the switch, is that something I can do myself, or required by by a mechanic. What would the cost be? Or would there be another reason tthat would be cause the problems I have decrided? HELP!!!!

Hi:
My guess is he switch needs replaced with a new one. I'm not sure what he did to give you the button, but I hope he hasn't damaged the wiring. Because of the involvement, I would recommend having it done by a qualified mechanic. My biggest concern is the air bag.

Do you have a flashing security lamp on the cluster when the vehicle doe not start?

engine sound like it wants to turn over but doesn't
Thus far I'v checked for fuel at the rail and there is good fuel flow from the schraider valve and I 've checked for spark on the front 3 plug wires and have good spark. So.... whats next?

You need to check the actual fuel pressure not just the fuel squirts when you press the schreader.Also is the security light on solid or flashing?

What should the correct fuel pressure be? And as far as the security light goes, it's blinking prior to actually turning the key

The fuel pressure should be 48-55psi.So with the key off and the key in the run position the security light is flashing?If so the security system is keeping it from starting by disabling the fuel injectors.

Your going to have to get a code reader and see what the exact code numbers are and let me know the exact code numbers.

will do! may take a day or two but I'll get"m

When I try to start my car when it is hot outside it will not crank. I have to keep trying until the ignition engages. Sometimes I have to shake the car, close the door several times or pound on the steering wheel and then it will crank over. Had this issue last summer then it stopped happening all fall and winter. Now the problem is happening again.

When this condition happens, the windows will not work, radio quits. Brake Pedal makes a clicking sound. Heater controls still work. Power lock will not work.

Once started the condition will continue off and on at random. The car will remain running but some indicator lights on the dash will turn off some will turn on radio will turn off and on with the condition but the car continues to run.

They have a basic code reader on amazon for under 20 and one that even reads live engine data for like 54 Keep me posred on what you find.

It sounds like what is known as "heat soaking." Have the electrical system tested. Battery. Alternator. Starter. Cables.

Ok we were able to get it started this weekend using Gumout carb cleaner. Trying to find a fuel pressure gauge today. So should the pressure be a steady 50-60psi? Seams as though if I leave it on each time the ign is put to the on position the pressure will always meet the requirements. Is this a correct statement.

The fuel pressure should 48-55psi you crank it for 5 seconds then see what the fuel pressure reads and it should be a steady reading.

as far as codes go, out of 15, 10 were abs codes ( he's got a lot of dummy light on ever since the mech in WV by-passed somthing so we get back home), 3 were evaporator type codes and the last 2, 1 was loss of communication and somthing about MOD bus communication fault.
Now the fuel pressure test was also done with the following results. Fuel pressure stayed at 54psi until the fuel stopped (timed out)at around the 5-6 seconds time frame and then dropped down to 48psi.

Thats not a bad fuel pressure reading sounds like you dont have injector pluse from what you have found so far.So what are the besides the abs and emission codes you have?I need exact code numbers not code descriptions.Also your security light is on solid or flashing?If so then thats why it doesnt start the computer has disabled your fuel injectors.Does your keyless entry door locks fuel gauge etc work?
