So I have a 01 ZR2 S10 and it still won't start first try. I crank and it takes a few seconds or I have to give it gas to start. I replaced the fuel pump, filter, distributor, cap, rotor, plugs, wires, and nothing has changed really. One time the truck even died out because the little metal piece in the center of the rotor button broke off on the road when it was raining. I just changed the distributor today and it is still hard to start. I feel certain that it is an issue with the spark but I seem to have run out of culprits as far as that goes. Any thoughts?
