Fuel Pressure Solenoid threw a code

[alIan]

Via palm'n'stein i'm getting a P1105 (fuel pressure solenoid malfunction) code (although palmnstein is unable to get the DTC, it gave me the code itself). I took off my FPS, applied voltage, and vacuum tested it, and it held 25 inHg no prob. i disconnected the voltage, and it flowed perfectly.

After recently wasting 70 bucks on a EGR solenoid only to find that the old one worked perfectly, i am very reluctant to purchase a FPS that will work no better than this one. I have checked the vacuum lines (the one from the intake mani is tapped for boost gauge, and gets vacuum perfectly) and they are flowing just fine, and all sealed up.

The CEL activates on a warm start as i would expect (since this is the only time a fuel pressure solenoid is used).

Any suggestions as to how i can get this code to start coming back? I already cleared it at least 10 times, and have reset the ECU once. Thanks!

anybody have any idea? I was thinking about unplugging it and hooking up a galvanometer to the terminal and doing a hot start to see if voltage reaches it... and if it does, just going to buy a new one....

any ideas appreciated!

Yeah just got this code as well. I just did a timing belt change myself but i didn't unplug the fuel pressure solenoid just unbolted it to move it to the side. I have checked the wires and hoses they look fine as well. Too bad no one ever replied with how they got rid of the cel in the other threads I found. Let me know what you find out about the solenoid.
