My blazer takes 2-10 times trying to get it started before it finally cranks, I have changed plug wires, plugs, distributor cap and rotor, starting coil, and had battery, alternator, and starter tested, they are good, and am still having trouble. No error code come up.

Without a service engine soon light, the problem is not something that the OBDII system monitors. What you're experiencing is a classic symptom of low fuel pressure. Check the fuel pressure and leakdown rate. Most auto parts stores rent/loan fuel pressure testers for free, and sell them for around $40. When you have one available, let us know and we can walk you through the procedure. Simple to do and it only takes about 15 minutes.
