Wow, I am without words really. I haven't visited the site in months because I just haven't had the time so I am just now learning of his passing. I actually had to leave the page for a minute and...
I can explain to you with confidence how the vehicle is configured which will answer most of your questions as I have intimate knowledge of those vehicles. I have no knowledge of EFI Live, but can...
No, I meant that I was assuming that this question was regarding the drivetrain swap he was working on and that the technical info I gave would pertain to the particular vehicle that the drivetrain...
There is a lot of interesting info there Shannen. I knew that if anyone had a decent answer it would be you. I was hoping that although slightly OT, my question might yield answers containing...
That part of the calculation was where I was a little uncertain about my answer thus my leaving it out of my reply. Your answer actually raises two questions for me though. They are related, but may...
This is just an educated guess based on your screenshot and experience. But, the driven wheel pulses per rev is based on the final drive ratio & number of teeth on the VSS reluctor. I am assuming...
I hope that everything goes ok. Best of luck to you Mark.
There is a possibility of getting just the connector body, but obtaining the part number would probably be easier through viewing the wiring schematics. If you view the portion of the schematics that...
Dave,
I BELIEVE that you are correct about how the ECM controls the fans and that is why your wiring and test results support your theory. That was how I understood the system to work going by the...
Wow guys, I didn't mean to spark off an argument here. I only took issue with being told I was wrong without an explanation as to why as I was confident in my knowledge of how these systems are...
As a matter of fact yes it is. I don't take issue with being corrected. It is the manner in which it is done. That being said, I would like to get back on track as well.
I actually thought that I...
I could ask you how much training you received from General Motors pertaining to their High Speed GMLAN network and how many GM engineers you have consulted with, but this is supposed to be an...
That's not what I have found in my experience or what I was told by the GM engineers at the training facility.
After looking at the schematics you posted it appears that the BCM may simply provide a switched +12v signal to all modules on the network to power them on. If you notice in the schematics, the ECM...
Wiring diagrams are split up into their corresponding category so sometimes they can be difficult to locate. I.E. The wiring diagram for a brake switch input at the ECM from the ABS system may be...
Dave,
Glad you found what you needed for the diodes. As for your need for info on circuits I have a suggestion that may be of great assistance. You can actually buy a trial subscription to the GM...
I know it's been a while since I posted about the diodes, but I've not had much time for anything lately. I'm not sure if you found any more info on the diodes either, but here are a couple pics I...
All personal preferences aside, I'm glad that you found a solution to your problem. On a related note, I feel compelled to state that although I prefer to use iridium plugs and that they are the...
Dave, after looking at that schematic I can tell you that the diodes are either integral to the fuse block OR the more likely possibility is that they plug into the fuse block like standard blade...
The vapor lock theory sounds like another very likely reason for the little orifice there. I hadn't thought of that, but it makes more sense than an air bleed. I never did understand why the TBI...
Here is your pic with notes illustrating what I mean. It's a little sloppy, but I think you can get the idea.

You've got the flow path backwards. The fuel has already reached the injectors and is on it's way out to the return line at that point. I do not know the purpose of the little orifice, but if the...
Mark, I have a brand new still in the box Turbo Sunbird memcal that I bought for a project that I never got around to. I will dig it out today and get you the p/n and BCC. PM me if you're interested.
.035" would be the ideal gap on that engine. I prefer not to go much wider than that on most applications. I've heard both ways on aftermarket "performance" coils, but I've never seen any hard...
