I am having the same issue, and have followed your troubleshooting to the extent above. Starting to think it is the PCM. Connected my autell code reader and indicates no faults (for what that's worth). Also looks like I have a high current draw when the car is off Key out. Had a noise coming from under the windshield cowl, and removed a horn/siren type of device. Do you know what that component is?
When attempting to starting the car also noticed the fuel pump does not come on for its aprox. 3 to 5 second cycle in the Run position before selecting Start. Believe this is also a PCM function. Running out of options on this, so any help appreciated
That is the famous-for-draining-batteries alarm siren. Many have replaced theirs, others just disconnected them and let it go at that.
TUrn key to START, if starter does not engage, release to ON.
Wait 45 seconds.
Does engine cooling fan warp up to high speed? If so, replace the RCM or send it to DJ for reworking.
If the engine fan does NOT warp up to high speed, we have other things to check. It is NEVER the PCM, avoid ANY garage that tells you the PCM is bad.
