Aircraft
After engines were shut down for over ten minutes; we noticed that one engine displayed and fuel flow of zero; while the other engine showed no data whatsoever in those fields. The engines showed different data; not abnormal; just different. We called Maintenance and he performed BITE checks; which showed that one of the engines registered internal faults on our previous flights that day. The aircraft was removed from service to perform Maintenance on the engine start switch. All operations and indications had been normal besides this discrepancy we noticed which prompted the Maintenance call.
