The ECM/Sol fuse under the dash is not blown but instead of a 10 amp fuse there is a 20 amp there. Just wondering if that makes a difference.
ALSO*****Could someone tell me where the wastegate solenoid is supposed to be installed? I have been looking behind the turbo near the O2 sensor and the "y" that connects the two hoses to the turbo and wastegate. Don't see a wastegate solenoid. There is a connection though that is taped off. Here's a pic.
The gray connector is the O2 sensor connector. The red one is taped off and I don't know what it is. In the back there is the Y for the wastegate and boost.
No longer available new. E-bay, parts for sale/wanted, this board, turbobuick.com parts forsale/wanted, RJC hybrid Boost Controller might bwe a good option till smog time. I am sure that if you advertise, someone will sell/give you 1, Brian Weaver (BWeavy) at GBodyParts.com, Michael MCCoy, Steve Wood, Dan (Grumpy) & Lou Czarnota might be able to hook you up on 1.
At the moment, don't worry about the 31. It will show up if there is no solenoid plugged in.
Tell us how your boost is being controlled? You stated you have the factory Y hosing.
One leg should go to the compressor housing, one to the actuator, and the third leg should go to the wastegate solenoid. You have no solenoid, so where does the third leg go? Is there a bleed valve attatched to it? Or what?
Yes I realize all that. I'll check the fuel pressure again with it off but I still can't seem to adjust it above 36 psi. I'd like to be in the 40's static. I think I just have a bad FPR. I'll also take some pics of wherever the boost is going.
From the Y there is a hose that goes the the compressor and the wastegate. But the hose from there goes all the way around and into the firewall...I looked underneath the dash and there are two thick hoses. One that leads to my boost gauge and another that leads to my glove compartment and there is nothing attached to it. Here's a pic of the hose that I'm pretty sure it's connected to.
This is the one in the glove compartment. Looks like the guy who owned it before just blocked it off or was preparing for a boost controller in the car?
Not meaning to hijack but I have 1 question. Steve, you said if the wastegate solenoid is unplugged it will set a code? Are you sure that unplugging it will do that? Mine has not been connected for a couple of years but has never set a code. :dunno: Stock ecm. Maybe because I have an extender chip? Might that be the difference? Just curious.
Think the fp regulater is leaking some of that vacume? I think Steve is heading you in the right direction. Hope you get it sorted out.
