## Discrepancy

FUEL SYNOPTIC PROBLEM.  THIS IS NOT A SYNOPTIC PROBLEM.  THIS IS A CNTR LT OVERRIDE PUMP PROBLEM.  SWAPPING ELMS CARD SOFTWARE.  NOW INSTALLED.  PUMP STILL RUNS WITH SWITCH OFF.  FOUND SHORTED WIRE FROM SW (101TL2834-3) ELCU THAT COMMANDS PUMP.  IDENTIFYING WIRE FOR RPR.  WIRE IDENTIFIED.  INSTALLED CONNECTOR.  INSTALLED ELCU (CTR L OVRD FUEL PUMP), PUMP OPS CHECK OKAY.
