    Hi David Fitch, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? Is there spark, fuel pressure, injector pulse? Is the security light on or flashing?

Do you have more info on what it's doing or not doing? i.e. Does it turn over/crank? Are there any backfires while cranking? Does the starter just click? Is there fuel pressure? Does the butterfly/choke open/close? Are you getting a strong blue spark at plug or a yellowish one?

Testimonial: "It will turn over but want start i have spark on the lgnition coil i get gas"

I have an 1990 buick regal custom and stalls when im griving it then dies can anyone help me on how to fix it.

Sounds to me like a fuel filter.When was the last time it was changed?Because if a car starts and runs till you give it gas under load then dies it is a fuel problem.Start by chaging fuel filter and if problem still persists then next thing to check is fuel pump.

Does a 2002 buick regal have a ignition position sensor

Hello trhino69.

The Regal has two position sensors.
One on the crankshaft and another on the camshaft.
If the crankshaft sensor isn't reading it will not start.
On the other hand if the camshaft sensor isn't reading it will start but the fuel injectors will revert to non-sequential firing.
The crankshaft sensor is mounted at the crankshaft harmonic balancer.
It is #4 in the diagram below.

you will need to remove the crankshaft bolt with an air impact wrench. Then you will need to get a balancer puller to get the pulley off.
