Message: [QUOTE="Short Bus, post: 1145476, member: 95"] I have a 2000 f350, 6 speed trans that has had intermittent fuel issues and now the problem seems to be almost all the time now. ALL fuses are good, all relays that i can find are good. However, there's only 6-7 vdc at the pump. Ground at the pump is GOOD when ohmed to negative battery terminal and measured 13.5 vdc harness ground to battery positive. I have searched hi and low for the fuel pump relay. Prodemand says its in teh fuse block on drivers side fender, it is not. Internet search says its in the dash below and to the left of the radio, it is not. Is this pump controlled strictly by the PCM? One thing i have noticed is that as long as the key is on, there is voltage at the pump power. It never times out and cuts power off like every other superduty 7.3 does. Does anyone know if i can swap in a spare auto PCM just to see if it runs the pump correctly? any help is appreciated.
