2G P1105 Code?

[Ohhchhittt]

I have a cel code that I was told could not be read. It's P1105. Any ideas what this code could be and what is needed to fix. Thanks

Could be fuel filter/regulator.

That's awesome thank you, the cel came on after I hooked up my boost gauge. My gauge seems to work when I am driving but at idle I thought it should sit at zeroabut it does not. It has no reading from it at idle. Didn't know if my gauge war messed up and making the cel come on. I checked my fpr and from a visual stand point it is good.
Would the boost gauge mess with the cel any

It's the Fuel Pressure Solenoid or it's hoses (not fuel filter/regulator). It's post #8 in post 2's link above.

Right, a fuel issue couldn't have anything to do with either of those. Just my 2 cents. And to answer your boost gauge question, it should never sit at 0 at idle, the negative reading on the gauge is your vacuum.
