Yes Normal speed. Yes to extended time cranking. If I turn key and crank about 4-5 times and then turn off again after which I wait about 30 seconds and try again, it will start pretty quick.. It almost seems like it's not getting the spark to fire when it's cold. I installed a new regulator for fuel and checked pump for power it was good. Injectors about a year old.
