#199 of 305 Turn the key.......Silence
Sep 27, 2010 (1:02 pm)
I have a 1993 Buick Lesabre. The body has 114 but has newer engine and transmission. I left for work and turned the key to my surprise.....Silence. The lights were bright, and the radio played. I went the next day and checked the starter, battery, cables, and connections. All were in great condition. Then I went and had another key made thinking it would be the Key Pass bar in the key. Still nothing. It wont crank over, not even the clicking noise you here from the solinoid. You do hear the fuel injectors kick on but they kick back off within a few seconds but that is it. The security light blinks but does not go off. I checked all the fuses and seen one where you can't see the inside. I was thinking the Ignition tumbler or the wires going down the steering shaft. I am at my wits end. If anyone has a clue......please help. I am losing out on work cause of this.

If the security light keeps flashing for 3 minutes after you turn the key 3 times and it doesn't get the right reading from the resistor in the chip, you probably need to clean the key resistor with a pencil eraser on both sides. See if that makes contact with the metal prongs in the key cylinder.
Dip the key in alcohol an dinsert quickly into the cylinder to hope to clean off the contacts IF they are dirty.
But most likely you need to install a bypass resistor set that you build from resistors at Radio Shack. Measure the resistance of your key resistor and see which of the 15 used it matches.
Insert the resistor link in the two fine wires inside the orange conduit that looks like a wire at the connector on the steering column. Use the wires going to the connector to short across with the bypass.
If you had not said the security light flashes for 3 minutes and then is ready for another key try, I would have said have someone tap the solenoid on the starter with a hammer while someone turns the key.
But the flashing light means your wires in the steering column have broken in two from the flexing of the tilt wheel...
Search for other info on the net with VATS, vehicle anti theft system.
And places that install alarm systems get the resistors in packs to use to bypass the GM setup. You might know someone there who is used to doing the cutting and splicing for you --without installing their alarm. Just bypass it and the theft system is gone, but your car will start. No one will know your theft system has been bypassed.

It's been a couple months since I posted about my issues with the car not starting and stalling (starter cranks, but no ignition). It's been working well, and I wanted to wait a good period of time before reporting back, just in case. Your suggestion of the crank sensor brought me to the right area for that particular problem. One day when the car wouldn't start I gave the wires going to the crank sensor a gentle but firm tug and it started right up and ran for two weeks without issue (it used to fail at least once a day). Then it did some sputtering on my way home one night after a couple weeks. I repeated the tug on the wires and again it ran without issue for another month before I had to do it again. So I think there is a connection issue there. The next time it is at my mechanic I will as them to check or replace the sensor and wires. Till then I don't mind having to jiggle them once a month. At least I know where that problem is coming from.
However the other symptom has returned where when I turn the key there is no starter. Similar to the recent posts from others. Turn key, dashboard lights stay on, but no starter. If I play with the shift lever and flip the key repeatedly it will eventually kick to life. Sometimes it takes 5-10 minutes. I haven't taken notice of the security light during these episodes.The next time it happens I'll take better notes on that and other lights. One thing I notice is that the car is usually on an incline (nose up) when it happens. Sometimes just a slight incline. It has never happened when the car is level. I'm wondering if it has something to do with the shift linkage when it's in park. Doesn't the car need to be in park to start? Maybe the contact that tells it it is in park is not making proper contact with the weight of the car rolling back twisting the linkage just a bit. Just a thought. I tried a brand new key from the dealership, but that didn't work. This problem used to happen only once a month last year. Then this week it happened three times (always on an incline). I'll report back with the status of the lights. Maybe it will help somebody else.

The car should crank in P and N. Put your foot on the brake and move the shift lever around and from P to N while the key is turned to Crank. See if you get contact in between.
The safety switch is on top of the transmission where the linkage goes in. You might tug around on it and check the connection there.
But watch the security light. If the VATS system is given wrong resistance readings three times to Crank, it flashes for 3 minutes before allowing another reading.
Remember the wires inside the steering column that connect to the key cylinder at the top may shift when the car is in a different position. The tiny copper threads in the wires may make contact then and not in other positions that shifts their weight slightly.
Also notice if the security light comes on while driving and goes off. That would indicate there is a problem with the resistance readings. Some people have noted that symptom.

Hey there, I need to find the location for the fan relay (radiator cooling fan) albeit it is an Olds LSS they are the same, is it in the maxi fuse center or inside the car at the right side kick panel? You are the most significant and knowlegeable tech here for those cars, as far as I am concerned. (not that the rest aren't) but any time I read here you go through a great deal of effort for free to those in need these days, and I cannot thank you enough Please tell me from left to right if in the maxi center, or from top to bottom inside the car. I know there is an isse I got a permanent code that stated the relay, I cleared it, but didn't drive the car long enough to see if will re-occur. ( the mice love this car, one commited suicide in it by getting himself jamned between the actuator controls, I found him there due to the wonderful fragrance) Must be the leather upholstry??? Thanks Bob 252.

Not sure what year this is for, but it should be close to right. you want the cooling fan relays on the driver's side.
Remember that several of these relays are the same part number. So if another one such as horn or AC compressor are the same part number, you can interchange them to test one that you believe is faulty.

I don't know if my 93 is the same, but it had the same problem, it turned out to be the crank sensor, after it was replaced the problem went away, also my 95 started acting out in a similar way, that one turned out to be the security issue from the 210,000 miles on it, but after some time and using the other key the light would stay on and there would be no problem with it dying out, don't know what else to offer, but both of those guys offering info are Excellent in their knowlege of these vehicles. I only hope that this helps. Bob.

Thank you so very much Imadoza, also if you are still here I did send another querie again today as it did not post for some reason, thanks again this info is not available anywhere including our local Libraries. Oh and about my rodent friends, Dryer Sheets??? the car is used daily. Bob.

Oct 12, 2010 (7:55 am)
Thanks Imadoz, I forgot to includethe year in my second post it's a 97 and only 4 relays are present, but now that I am armed I can change them out with some spares that I do have, I can't thank you enough as I am retired and don't have much cash, stay well..Bob 252.
#208 of 305 Relay Problem-Cooling fan buick/Olds
Oct 13, 2010 (10:19 am)
Hi All, I have a code P1651, which was read from my Inova 3100 reader, the code in the book suggests it to be a relay, the car is a 97 Olds LSS, I also looked at some other sites to find what this code is and found other info that is or is not correct, the statement there was PSP input malfuncton, of course the engine light is on. I have replaced the relays and this did not correct the problem, so where do I go from here? Thanks Bob.
