I have a new AC Delco knock sensor coming. As soon as it gets here I will continue diagnostic with the chart.

I checked the wire to the knock sensor and it is good. I think I might have a bad knock sensor. I found a video to bench test the sensor with it mounted in a vise hooked to a voltmeter. When you hit the vise it should give a reading over one volt, it does not. Does this sound right? If the sensor is bad, would that cause pin B7 to not show voltage?

I have to leave town for a week. I will try all of those items when I get back. I do have an unrelated question, behind the instrument cluster, upper right hand side is a 25 amp fuse, see photo. Is this related to the factory alarm system this car has?

Ok Steve, I have no continuity between E and the ESC. I have a good ground at D. I have 12 volts at B. At B7 on the ECM I am not sure how to check. What i did was try to check the back of the plug while plugged in, don't think my probe could get in there. I installed a knock sensor from Casper's which attaches to the wire at B7. I tried to get a reading at the solder joint, but was getting a reading of .067. where should I go from here?
Also I replaced the knock sensor while I had the engine out. 20

I can't get to it till Monday, but I will check those first and get back to you.

Thanks, this gives me a place to start. Could a knock sensor installed too tight cause this?

I want to thank everyone who has answered my questions over the last couple of years. I finally started my car yesterday. I was surprised it started right off. Have a couple of minor leaks to address, but overall running good. My scanmaster reads BL of 124-128 at idle depending on which time I start it. TPS is .42. Now the bad, I have Mal code 43. Bad ESC or wiring. I can get a new ESC Module from NAPA for $220. Is that the way to go, or does someone have a better suggestion? I have included a few pictures of the progress. Again, thank you all!!

I did not know you could clock the turbo. Thank you so much! I will consider both options. Anyone have a suggestion on the hard vacuum line?

I am finally getting my car back together. I purchased a new stock replacement turbo from GN1 Performance. After getting it installed the inlet neck doesn’t line up with the intercooler very well. Did I mess up somewhere? The intercooler is down as far as possible. Is it a turbo problem? Should I have had my original rebuilt? Or am I making something out of nothing?
Also would it be a problem to replace a hard vacuum line with hose? 26

Here are some pictures of my progress so far. Every thing under the car is done along with what you see.

That’s what I have figured out.

Thanks, that’s what I’m looking for.

Ok, sorry for the confusion. The original picture is the rubber connector from the hard plastic line to the MAP sensor. It is cracked and I want to replace it somehow.
The second question, I converted to vacuum brakes. I have seen pictures of some cars that have a check valve in the larger diameter vacuum hose from the plenum to the brake booster. I am having a problem finding a check valve for a larger diameter hose. Do I even need one there? Below is a picture. 30

That actually goes to the passenger side fender. I will try the Autozone kit. All the parts stores I have tried do not have a check valve bigger than 1/8”.
