A few weeks ago I left a friends house and went to start my truck and it just turned over. I had the truck towed home and started diagnosing. There was lots of fuel, and compression, but no spark, I replaced a few parts that i thought could have caused the problem. Cap, Rotor, Wires, and the coil. Still nothing, there is adequate voltage going into the coil, but nothing coming out. There is a good signal from the PCM also...I'm lost.
