Hard Start
 

Hi Everyone. I was wondering if anyone has seen this before:
Lately I've been having an intermittant issue. when I start the truck, 1998 4Runner, v6, 165,000 miles. it will turn over but not start. I have a good started motor and a good battery, so turning it over multiple times in the morning so far has not been too much of an issue. but, some times I need to turn it over 6 to 10 times before the motor starts. any idea what could be causing this?
Any help would be deeply appreiciated

thanks
DM
