Put in a new battery, all light in dash come on but when the ignition is truned it won't start, unless i go under the car and use a scew driver then it starts i can try it for about four or five time it stil starts,but if it sit a while it want start again have to do same all over again is there a relay for the startyer if so where is it located

Click on the link, you can see the start 1 relay, underhood fuse box. You can see the start circuit breaker and pcm fuse. Not only check the circuit breaker and fuse, use a test lite and check voltage at fuse and circuit breaker. The CB is hot all the time, the fuse goes hot with key on.
I noticed in the diagram, the start relay has no pin numbers on it, sometimes that means the relay is soldered into the fuse block circuit board, you can't pull it out. You can try to pull it? The ground for control side of relay is grounded by pcm. I didn't see neutral switch mentioned in diagram, that switch is a thought. Just my opinion.

Hi......
On your Buick 94.
The problem is the ANTI THEFT SYSTEM..
If you have replaced the ignition switch.
If you are using a NEW KEY, the car won't start.
Because in the OLD KEY, is there a Resistence with a number of ohm's
The computer need the resistence to activate the the signals to operate the vehicle.
OK.. with the New Key and Old Key you can go to any Aloha Smith and they will remove the Chip from the Old Key to the New Key.
And the car must start and running.
But if you are using the Same Key that you have before the repair made.
I recomend to check the 2 Orange wires from the Ignition lock Cylinder to the steering column lower connectors.
Ok I hope this work for your problem.
Any moree info, I will glad to help you.
I'm a Mechanic and have all the repair information for all the cars.
Thank you for use fixya...
SOURCE: 1997 LeSabre- Security light in dash is constantly
ok the security light is on because it isn't reading the chip pellet in the key. The problem with the is usually either bad key, bad pickup in the cylinder, or bad paskey unit. if it is the key or the cylinder then you can bypass the unit by adding a resistor to match the key resistance and attach it to the violet and white wires at the bottom of the column. I do alot of bypasses on these passkey units, it works wonderful.
Your stalling however sounds like a different problem.. since the security system only disables the starting feature and not the running of the vehicle. But with the 3800 engine the cranshaft sensor or sensor wiring, as the engine gets hot causes shorting to the computer and shuts engine down. I would look into that to solve your problems.
Testimonial: "Thanks! I have had the crank sensor replaced twice in the past 2 months, the new one just last wk.Also cam sensor, coils, wires and plugs. AArrg!"

Lisa, how long was the key in the one position? For the heck of it, put the car in neutral, and try to start it. It's possible the neutral safety switch is bad, which could cause the problem. It should start in neutral if that's the problem. Let me know if this works, if not, I'll help further.
