Troubleshooting an issue where APU will reach about 20% RPM no ignition and also getting fuel. ACAWS screen throwing APU START 123 ECB TO. Any seen this before ?

Not sure what you are doing to troubleshoot this but it's pretty easy to start.

1.  Start diagnosing the tripped open ECB IAW 24FI for tripped ECB.

2.  Swap/R2 APU relays and check all power connections. 

I would caution resetting the ECB multiple times until you figure out what is causing it to trip.
