Hello,
Typically EGR won't keep the vehicle from starting. It can run poorly when you start it if the EGR valve is defective.
Is there any trouble code? If so do you know what they are?

There could be several reasons for a vehicle to not start.
Could be for lack of fuel or ignition related issue.
Does it crank over?
Here is a video of how to test EGR valve:

Please let me know if you have any questions.
Thank you.
