2000 Zr2 Blazer... to get her to start had to turn the ignition over then shut back off and turn again. Issue has continually gotten worse to the where it's taking about 15-20 turn on and turn back off and on again to get her to start. Can hear the fuel pump running so I'm thinking it's the ignition. Need to know where to start and if I can take it in and have it hooked up to a machine before I have something else fixed on it that doesn't need done.

 

Please take a quick look at the "Coolant Temp Sensor". Probably on the top of the intake, close to the thermostat housing. Two wires and a plug onto the sensor. Make sure the body of the sensor is not cracked or broken and the plug is properly connected.

Without this sensor, the computer thinks your motor is 40 below zero and will pump much gas into the intake.

 

You can test the ignition switch using the schematics in the link at the bottom of my signature.
