93 3.0 No spark

[Randall_P]

I just replaced the cap and rotor,plugs and wires and brand new battery. The problem is twice now it just hasn't started rolls and rolls just no spark? Any ideas? Im figuring its the coil but any advise would be great.

Are you getting 12v to the coil primary? Primary needs to be turned on and off to generate secondary high voltage. You can use a test light to see on/off sequence of primary as you crank. If no on/off primary then trace to switching electronics. I'm not sure what does the switching on your year truck, mechanical or electronic. Spark also needs to be bright and blue, not yellow and weak.
