Re: I Think I Killed my 84 SFI, No Spark.
 

ok, off to talk to NAPA for a few about this sensor for crank. see what the story is...maybe they can she some light on this sensor.
I did how ever manage to mount the old sensor in the new style holder they sent. you see. the holder no longer comes seperate and is why they sent me the whole thing. I figured it to be a retro fit....
but as I said. I have managed to mount to old one in the new holder, once I removed the metal jacket that came secured to the new sensor. the new holder is set wider and has a grove for the sensors metal jacket to slide upon instead of securing to the sensor body it's self.
My only thought was that maybe the depth was effected and sensor though looks correct may not be deep enough to sence the grove.
follow all that?
probly not....lol

Re: I Think I Killed my 84 SFI, No Spark.
 

From the info I can find, it does appear that the 84/85 and 86/87 sensor differ. The 84/85 unit is:

Standard PC11
BWD CSS9
Autozone / Duralast SU158
NAPA / Echlin ECHCSS102 (Bracket only CSB201)
GM# 12537108,
AC/Delco 25525667

And it does look like the pictures I posted.

Re: I Think I Killed my 84 SFI, No Spark.
 

ok, NAPA has lloked and still claims the sensor that keller showed as gpi.jpk is the one the book lists. also matches to numbers provided by keller (NAPA / Echlin ECHCSS102 (Bracket only CSB201)).

mine looks like Kens photo1.jpg except my sensor has the 3 wires and connector built right on it, not a socket that harness fits into...
so in short... kellers infor on the bracket number is the type they sent me but is not the same as I have/had.

I did manage to find (in all thse print outs), a parts list with numbers that I believe came from this site ( but Dammed if I can find it ), that was/is for 1984-85 "g" Engine Emmission Controls-3.8L V6 LM9/231-9), print #4G03-011.

I also seem to have a print out for a 1984-85 "E,G" Engine ASM-3.8L V6 (LM9/231-9) turbo charged, print #4M00-002, which looks and seems like the one I need. but I can not find a part numberonly clearance specs.

any idea what the diferance between "G" and " E,G " or what the ASM stands for?
looks like prints origanated @ 1989 General Motors Service Parts Operation-buick-44W

Re: I Think I Killed my 84 SFI, No Spark.
 

I believe in cause and effect.

I say this becouse I just went back and tested Cam again with key on and Cam sensor out, did a rotation test and again saw 7.8 volts, when cam is turned it rises to 8.0 as window passes...so with key still on. I removed cam sensor from cam.. no change to voltage, still reads 8.0 volts. place cap over sensor and voltage drops to 7.8 with window not at sensor, remove cap and voltage returns to 8.0.

Re: I Think I Killed my 84 SFI, No Spark.
 

Your engine code is an "LM9" or just a "9" as the VIN lists a "9" for engine code.

The car is a "G" body. There were "E" body cars as well. They would be the Riviera. The Riviera in 84/85 was also available with the turbo motor.

I will mention that I referenced backward from at least one of the numbers that I mentioned on the acdelco.com website and the "finned" style is shown for both 84/85 Turbo Regals and Turbo Rivs.

Know where I found it cheapest? Rock Bottom via eBay. http://cgi.ebay.com/ebaymotors/Crank...171210001r7234

Re: I Think I Killed my 84 SFI, No Spark.
 

the sensor shown on the ebay is what they say the book shows.and is what was sent.
I referenced about finding the G/E on one of the prints due to the drawing showed the same looking part(as far as drawings show) and the drawing I have is evidently a list of tolerances becouse it does not show a part number.
the part on ebay states the part number as 25525667 yet the drawing I found stated number to be 25525867, which according to NAPA don't exist.

so wonder what I would find if I looked for 84 riviara turbo. perhaps the motor was a switch out?
did I mention that this is a Limited Edition car...
were the parts limited eddition as well...lol
yes, I have lost it...

Re: I Think I Killed my 84 SFI, No Spark.
 

Aahhh. found this, which is what led me to ask strange questions
http://www.gnttype.org/techarea/imag...ne_part1-1.jpg.
part #50 of the drawing. but with the heading on the page, I was unsure why the "E" had shown up in styles

Re: I Think I Killed my 84 SFI, No Spark.
 

That is a list of part "group numbers".
May just be a mistype.
You'll find the same part number.
Who cares?

Perhaps it is time to consult someone who has worked on these before. i.e. Jack Cotton at http://www.cottonsperformance.com/ may be close to you...

Re: I Think I Killed my 84 SFI, No Spark.
 

ok, pulled the sensor to compair both

Attachment 1644

and checked the height and found new sensor sits a bit lower.

Attachment 1645

so, not sure if sensor is sitting deep enough into the outside grove.

well, I see that I have pissed you off as well. so thanks again for the help you did give and sorry to have wasted your time...
