No power to fuel pump
Hi,
I have an issue since last month where I have no more power to the fuel pump.
I tried all the common issues with no luck.
No power to the fuel pump connector outside of tank
What have been checked already:
- Main relay is good (brand new + CEL/battery light on key on)
- 15A engine fuse under dash is good
- Fuel pump working when feed 12v directly
- No priming even with fp/gnd jumped on diag port
- Connectivity in the wires from the under dash fuel pump relay to the tank connector
- Tried bypassing the fuel pump relay under the dash
Am I forgetting something before feeding the pump directly on a switch 12V ?
