I have tried everything and need help I’ve replaced the crank position sensor twice and tested the one that’s on there it’s good tried ignition coil, cap, rotor, plugs, wires, 02 sensor, computer, relays, fuses, pick up coil in the distributor, ignition switch everything I’m starting to think because the wiring under the dash is janky I don’t think the computer is getting signal to spark can someone help me out there and give me some ideas on what to try next thank you I also have checked all grounds and cleaned them.

I’m having a similar problem when the engine gets to operating temp and higher. As I understand it, the spark voltage comes from a relay in the relay box under the hood. Look for a relay labeled ASD. That is where the ignition coil gets positive volts. The ground goes through the ECM. Do you have supply volts at the connector to the ignition coil?
