No Start, No Spark!

I drove my 02 z28 this morning and it ran fine. Now i went to get lunch it just cranks. I smell plenty of fuel but have no spark. Ive also been having other electrical issues this month. Gauges go to the peg except speedo oil psi and volts. And it keeps turning the ignition on with out the key in it. The intake manifold was off about a month ago. Maybe a set of wires got pinched? Anybody have any ideas to get her started?

check the main coil wires that connect to the coil pack bracket. it could be loose or something, if its not that then all i can think is pcm related. could be a bad alternator/battery?

Battery is new and i checked those connectors. I have no spark on either bank. I put a tech 2 on it and found no rpm signal so im leaning toward the crank sensor. Im goin to probe that connector sometime today and figure out if its the sensor or the wiring.

Did you check your ignition relay under the hood. You can do a quick check by swapping it out with the fan relay.(Same relays) I had one that was intermittent one time.
