AnalogRead on Mega not responding

There is a mismatch between what is set as an INPUT and what you are printing to the serial port.
I'm not sure if there is a difference in the default pinModes between the Uno and Mega, but that could also contribute to your problem.

const int crashPin1 = A0;

void setup() {
    pinMode(A0, INPUT);    // not A1 as in previously posted code 
    Serial.begin(115200);
}

void loop() {
    Serial.println(analogRead(A0)); 
}
