Hi, My name is ***** ***** for the delay.
I will do my best to assist you
the fuel pump runs all the time with the key on but doesnt run when the engine is turning?,,is that correct?
from the way youn explain//it sounds as if you have one of two posible problems
1-the fuel pump relay
2-the ecm[engine computer itself]
the feul pump should only come on for 2 seconds when you first turn the key on,,then,run all the time the engine is turning
if the relay isnt sticking,then i think you will need to replace the ecm,,it is sending wrong signals to the relay
