Received error code 43 on my nytro - was told it was the relay

Customer Question

Received error code 43 on my nytro - was told it was the relay sensor so we changed that with much difficulty as they are very hard to get at. Still receiving the error code 43. Is there anything else to check for?

Code 43- Power supply to the fuel injectors and fuel pump is not normal......Probable cause of malfunction......open or short circuit in wiring harness, or malfunction in ECU.Was this checked ?

You are talking to an amateur here, what exactly does that mean? ECU??
Expert:  Tom replied 6 years ago.
It's either the main computer has failed or a damaged wiring harness or ground to the injectors or fuel pump. Hoped this helped. Positive feedback and bonuses greatly appreciated.
