Question about Buick Regal

Does a 1991 buick regal have a stater relay

Car will not start with key. I wired a 30 amp switch under the dash to bypass the neutral safety switch, which I replaced with no luck of starting with the key. The Car starts using this switch. If I take the wiring connector off of the NS switch, and jumper the two heaviest wires together, then the Car will start with the key. I'd like to figure out what exactly is the problem, and correct it. Does this '91 Regal have a starter relay? Any help would be greatly appreciated! Thanks! Ron

There's only 2 more things that I can think of, check the fuse for the ignition, then the computor itself, you did everything else.It might be the problem and may not.

SOURCE: 1999 Buick regal Security light on. Won't start.

I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

I don't think so. I got a 95 and I've done all kinds of electrical checking for various things and to my knowledge there isn't. There's fuses for the ignition and engine along with other electrical items but no specific computer fuse that would turn off a computer. I assume the car won't start?

If your car is simply not starting it could be something as simple as the neutral safety switch if you only hear a click turning the key. Disconnect under left side dash. White and has a green and black wire coming from button behind clutch pedal.

If car cranks but just wont start then could be numerous things. Check the 30 and 40 amp fuses under hood. Make sure battery terminals are connected tight and clean with brush tool if needed. If battery is fine and charged, I assume you have checked, then I'd focus on the ignition system.

ignition switch (in steering column)
neutral safety switch (disconnect above pedal)
starter relay (under radio)
starter solenoid

If cranks then neutral, ignition and relay switches are fine
If clicks then ignition and relay fine but neutral switch or solenoid may be bad

I have a 1995 Buick Riviera with a 3.8 supercharged V6. Vin# 1. It's a series 1 L67. I am having a problem with the security on this car. When I put the key in and try to start it the security light comes...

Next time it happen.

Put your foot on the brake,shift the gear selector to neutral "N" and start the car.

There is a switch call neutral safety switch and it can be intermittent.

If you can start the car in "N" and not in "P" then neutral safety switch is at fault.

Replace it as soon as possible to prevent damage to the wiring and transmission computer.

Also check for the key that your are using daily.

The resistor dot contact can be worn out.

Try the spare key and see is the problem follow,

Google GM VATS BYPASS is your are dead set on bypassing this setup.

95 regal wont start change the stater no change change the ignition switch on the colum no change what could it be

The security light is on or flashing? Your key is the one you always have uned or is it different? The key has a black chip near the handle, Is it clean? The wires that it connectes to are right inside the lock is it clean and not buggered by the wrong key or other object? The wires that come off this connection break near the lock.( flex every time you turn the key) A scanner connected to the car will pick the problem. Rember that the car starts in neutral and park both but not in gear this switch on top of the tranny fails and sometimes it'll work in neutral. Jumper wire at starter makes it crank? with key on start. Crank and not start your back to the security system. Cars plenty old enought to fail

Where is the starter relay on a 1996 Buick LeSabre? The car will start if the starter solenoid is jumped across, but not with switch only. I need to check the starter relay, but can't find it.

ok. the relay is under dash drivers side left of the steering column. now first check for power with key in the start position. at the heavy yellow wire at the relay and then check the purple wire if both have power then your neutral safety switch mybe at fault. check it as well. check for power at the switch bolted to transmission. the two heavy wires going to the switch will be starter in and starter out. so check for power at the two there if power goes in but nothing comes out the change the neutral safety switch.

How can i bypass

You've got a tough one here...can you crawl under the dash of your Buick? Do you know how to use a multimeter?
If you answered "yes" to BOTH these questions you're 75% of the way there!
#1. remove the lower "shelf" part of the dash directly under the steering wheel. Locate the TWO Orange wires coming from the steering column. Using a multimeter, place the pos/neg probes on either side of the tiny metal chip on your ignition the value. go to Radio shack and buy that value of resistor and pick up wire "crimp" connectors for 12-14ga wiring. Cut the Orange wires and bare 1/2" of each end. Crimp the resistor between Orange wires using the crimp connectors.
Good Luck
