Hard starting issue?

[Tophatjimmy]

I searched, but didn't find anything conclusive.
With my Sy, I have to crank it for like 10-12 seconds before it starts, OR I can crank it for a second or two, stop, and then it fires right up on the second try.

What the heck would be causing this? Is this a purple wire issue? Ignition module?Something else?

Any help would be great, thanks.

Check all tune up parts and fuel pressure.

I am guessing fuel pump. It's taking longer to prime the rails which is probably why you can hit it a second time and it starts. If it's turning over like normal, it's not the purple wire syndrome. Highly likely fuel related. This always seems to be the case on stock trucks. Get a Walbro and an AFPR.

Turn key one click so the pump runs,hold it for a couple sec (my guess 10sec).
Then start.
If it starts immediatly I bet it is the checkvalve in the pump that are stuck open so the fuel in the pipes/lines runs back into the tank.
If fuelpres is fine while driving its doesn't matter.
