I recently had p1105 pop up. I know it's for the fuel pressure solenoid. I tried to run it without the vac lines going to it, then switched out the solenoid to a different one. Then I took my multi meter and it is getting power when the key is turned and I directly wired it to the ECU pin #3. It still trips the CEL. Is there any other causes for this code?
