91 jimmy sle, 4.3l, 136k.
while driving the other day, with headlights on, i
noticed the voltmeter on the dash slightly fluctuating
when i turned the blinker on...
any clues?
also, sometimes it's hard to start...especially when warm, i have to turn the key a couple times before it
kicks in...
thanks for any help...

Get the alternator and battery tested. And also the fuel system pressure.

What's happening is when you turn key on and off you're building up pressure, again check the pressure.
