Took car to AutoZone had hooked up to machine said it was a fuel rail red seafoam through it still didn't clear problem up. Now the car when I start does crank over and tries but will not start. Did replace fuel rail sensor before I took the AutoZone it would go but pick up speed very slowly then it just cut off on me. Now it will not start.

Good afternoon,

I would start by checking the actual fuel pressure. Low pressure will cause this.

What was the code that was set?

When you crank the motor, does the tach on the dash move up a little? That will tell me if the crank sensor is sending a signal.

I would also check the compression.
