OK, there is a solution to this madness!!!!! There was a loose cable at the ECM!! Now with it back in place the car starts every time!!! What a crazy thing but the code ECM2400 said to check wire from ECM to CEM. When doing this i found a loose wire!

Volvo Horns to Rick back in April!!
Are the other codes all ECM-XXXX?

Check the wiring to the fuel pump relay.

ECM-2400 Fuel pump (FP) relay. Signal too high or too low. Permanent fault

Possible source
Signal too high:
short-circuit to supply voltage in the signal cable
Signal too low:
short-circuit to ground in the signal cable
open-circuit in the signal cable

Very good! There was a lot of other intermittent stupidity going on also so I figured it was because the car had been sitting here in the FL heat/moisture. Removed ECM, sprayed contact cleaner and waited a few mins for it to dry and then assembled again. CAr runs like new now again!
