so this has been happening ever since i bought the car ('94 gsr)...the radio turns off and back on whenever i turn headlights (or anything electronic) on...when the motor isnt on the radio will repeatdly turn off and on...also sometimes it takes a little longer to start than usual...i have to let it crank for an extra 3-4 seconds...also theres a creaking/scratching sound from my rear suspension and im thinking its my shocks but its not as bouncy as i thought it would be if my shocks are completely blown...any help would be appreciated

 

sound like bi3ch wire problem. real pain.

and sound from rear, is your car lowered? bump stop? brusings?

 

im on the stock suspension and the car has about 128k miles on it

 

+1 for wiring.....

 

get the manual , test light , and multi meter out dude , you got some tracing ahead of ya , lol.
