Hi. I need some help. My Blazer was running fine. After driving 300 feet and out of my driveway it stalled and I can't get it started. The battery and starter is new and strong. It turns over very stongly but won't fire up. I also put in a little gas into the air intake to see if it would fire some, but it did not.

 

The next step is to check and see if your spark plugs are firing.

 

Thanks. I tracked it down to a faulty wire that goes from the ignition coil to the distributor. I got a new wire and it now runs like a charm!
