When you say at night you could see the spark, during the daylight could you not see it? The reason I'm asking is I have a 01 TJ 4.0 with same issues, no pump priming, just cranking. Pulled coil pack and plug and saw no spark yet I did get shocked some when I bumped my finger on it while it was being cranked. Also, no fuel pressure obviously and no spark I'm thinking. Next step is testing the power lead to the PCM and then the cps connection. Do you know if its true that if CPS goes out, it will prevent both fuel and spark?
