Asked by for the 1997 Chevrolet Express 1500
In order to attemt to anser your question we will need more information.Does it crank at a normal speed or slowly?Does it crank for an extended time?The more you can give us the better we can help you.
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.
