1991 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic

the car is not wanting to start in the mornings. It rolls over just fine but doesnt want to fire. Takes ten to thirty minutes or even longer before it finally starts. Once its started it will continue to start fine the rest of the day

Welcome to the forum. How long since a tune-up? When it refuses to start, have a helper crank it, while you check for spark at the plugs. Also, use a gage and check fuel pressure.

Gettin fire to the plugs and has plenty of pressure off the fuel rail. Wondering if it could be the fuel pressure regulator starting to go bad. Sometimes while its rolling over it sounds like its backfiring thru the throttle body
