I released the pressure on the fuel rails, then pulled them to get to the spark plugs, and changed them out with new ones. Then I put the rest of the parts back on, and tighten fuel rails. Now the car won’t start. All it does is crank over and over. Please help please detailed answers.

Hi,

Are you certain that all connections (electrical) have been made? Are you smelling fuel when the key is turned on? If you use starting fluid, does the engine start and then stall?

Let me know. I'm trying to determine if it is a fuel issue or ignition.

I attached the directions for the removal and replacement of the injectors. Take a look through them and see if there is anything that you may have missed. Also, when looking through them, you will notice the numbers jump. I deleted the procedures for a natural gas vehicle and only included the ones for a gasoline engine.

Let me know.

Joe
