It may be the O2 sensor or the MAP sensor on the engine. You may need to check the fast idle control valve if it needs cleaning or just adjustments. Also check on the wiring and for some loose ground wires. Especially on the ignition system (high tension wires to the plugs and the ignition coil). New cars would have ECU's that are reliant on electrical signals for it to work. I would also suggest to have a scanner run to the system to see the error code indicated by the check light.

It sounds like just a coincidence. I dont know what a GRR noise is supposed to mean. It either Cranks, No Crank, or it Cranks but does not Run. Just tow it to a qualified shop and find out what the problem is.
