DaveEscos, Un plug the ecu and turn the ignition on,
If the pump runs the the relay has been wired to run permanently or
the relay is jammed.
However, If the pump is running continuously, this WILL NOT stop the car from starting !!!!!!

Some chips dont drive the fuel pump relay output properly as this is used for
other features like ALS etc....
(PECTEL/AHMED chips mainly)
In these situations, the pump is rewired to run continuously.

If however, the pump is wired correctly and working properly,
if it runs continously when the ecu is plugged in only,
then I suspect the ECU and/or chip has failed
