Problem -> pump not coming on when key is in on position
Where I am at:
- I have tested the pump out of the truck by connecting the ground and hot pins to a battery and it runs
- Fuse is OK
- 12.3 volts going into fuel relay
- red wire on relay when key is in 'On' position reads 11.5. volts
- red wire coming out of EEC relay going to fuel relay also reads 11.5ish volts
- voltage at intertia switch (which is bypassed) is 11.5 volts
- voltage at power wire on connector to pump is 11.5 volts
- voltage at black ground wire on connector to pump is 0 volts
The pump is still not working, so I am misunderstanding something.
