92 Silhouette stalling out

[trent1960]

Hi All,
I'm desperatly searching for help. I have a 1992 Olds Silhouette 3.8L that stalls out after it's been driven for a while. This happens when I'm decellerating or if it's sitting idle. This seems to occur more often when it's hot outside. So far, it's not stalled at high speeds. I've determined that I'm getting no spark when it stalls out. If it cools down for 10 to 15 minutes it will start back up. Sometimes it stalls out again right away. The plugs, wires and coil packs have all been changed.
Any thoughts?

Have a similar problem with a 96 3.4L dealer just told me it was the fuel pump

Replacing the fuel pump fixed my problems, which were exactly what you decribe, except for the no spark. How are you testing the spark?

Pull the spark plug hold the plug wire(using pliers or some other tool with rubber handles) about a quarter to half inch from the spark plug, have someone crank the motor, you should see a spark. Only done briefly, you don't want to short out the car.
You can hear the fuel pump engage when the key is turned, so the fuel pump has been ruled out.
I've had some outside advice that my problem could be one of three things. The crankshaft sensor, the ignition module or the computer. I guess I'll start with the cheapest and work my way up.

Thanks for your input. I'm glad you solved your problem.
