Hissing noise after engine is turned off, engine would not start after.

Edit.

So the hissing and grinding was when the car was shut off?

Ps: the starter is on the front of the engine under the intake manifold.

Yeah I know well where it is as I changed it 3 months ago not easy to get to it, had to take the manifold off completely, if there was something not put back together correctly if would have shown that in past 3 months.

Never had issue in past 3 months, not sure why coolant level would not make car turn on.
Noise was coming from the front of the engine and it looked like a relay clicked and then noise stopped..since I cannot turn the engine on..Had car towed back home today, wont have time to check it until weekend, have order one of those OBD2 readers and hoping that this will read out fault code, if not will need to check if starter is the cause again as I don't think it is a fuel pump as it engages as you try to turn the car on..not sure what else it could be, any other relay issues anyone experienced similar to this..fuses looked all good, need to check main relays as they cannot be really checkd and inspected visually....
