2003 Impala

Having Intermittent starting problems with Impala No start. Had terminals and cables cleaned and re tightened plus it passed full load test on battery. When no start I still have full power to lights radio and alarm. Please help left my wife stranded at work at midnight

Starter or starter solenoid is probably failing. If it happens again try smacking the starter with a hammer as you try to crank it. If it starts then you know you need to replace the starter.
