Hello,

So just to clarify you had the no start issue before you change out the pump and relay?
Before you changed the pump, did you test to see if it was indeed the pump?
When you turn the key, can you hear the fuel pump come on?

If your car throwing any codes?

You should have about 57 - 64 PSI of fuel pressure with a good pump.
Please let me know of any questions.

Thank you.

So it cranks but no start, right? Can you upload a video of the noise?

You could have a faulty crank position sensor.

Is there any codes? If so that might point us to the right direction.

Next item you should check is to see if you are getting spark. Could a issue with the ignition relay (I have attached the location of it).

Let me know if you have any questions./
Thank you.
