My blazer doesn't turn on, and I have checked the following:
It has fuel pressure but no spark on the spark plugs.
It has signal on the coil still no spark on the wire from the coil.
I also took the coil to get checked and said it was good.
Can someone help me figure out what I can to get the coil to send spark to
the spark plugs? I am lost at this moment, and don't know what
I can do to check it ...

Of course you've tried a different wire. lol..The only thing I can think of is, make sure the coil is mounted good. The bracket the coil is mounted on has to be grounded.

 

Brother,It Sounds Kinda Like You And I Have A Similar Problem.
Mine Is On A 01LS Xcab That I Just Put A Used 27K Sonoma Motor In. EVERYTHING seems To Be Working,But No Spark From Initial Crank Over. And I Used ALL,crank Sensor,Cam Sensor,Coil And ICM from My Original Motor That Was SEVERELY overheated Prior To Me Getting The Truck.
