i hate to tell you ,if you can not get code 12, or some others. (blank is not acceptible)
1: dead ECU ( stuck in BACKUP mode , this is where car can barely run and badly !!!)
2: Jumper placed wrong, next to bettery , 4pin cars and 6 pin cars see my link in my sig.
3: power to ECU is bad. ( that includes ground and 12 on all pins marked as such)
92 should be 4 pin plug with dangling rubber cap (yes).
next to battery. for sure.
the tang ( tang = lock latch at 12 pm) jumper 2 to 7 pm (b to C if you can see tiny print) Some call it Paperclip to 27 . regular size works best !
the jumper can be placed before or after starting. I like before , as is safer.
so your TIE (heheheh) doesnt get caught in fan to the right. ( a very serious
try both ways if you get blank , ok? be careful please.
In my opinion all these old cars 90-95 , must have the caps changed out.
I made list of parts from Mouser.com , last night on my web page,under , well here:
$1.30 if you can handle a soldering iron, ask friends. for help. many kids can do it or old poops like me.
Getem out of there, they are crap.
if you live in N. Canada , some seem to be ok,
its that 15 years of cab heat up to 150F that kills them.
if they say RUBYCON in black wrap , they are junk. Blue ones last. < observation.
the ecu choices are vast:
$70 fleebay or 100 or 200 depending on warrantee or ship first , core later rules.
$1400 from suzuki
or if 96 or newer $3650 from suzuki <<< see post last week , wow !
there are choices , besides what they say at xxxxxdealer.com.
BTW: some honest dealers offer rebuilts ( few).
the other fact is there are major rebuilding centers all over the country.
the can be found by searching using GOOGLE and for ANY CAR.
if you are in a panic,just buy the radioshack parts of the same uF and volts.
both can be higher , and it only has to clear the lid.
they are brute force filters, and do not TUNE something.
hope that helps. ( doing electronics repairs since 65' and like to help others )
i am working up a BOM build list at digikey so folks can just enter magic name or click a link and the parts order will be instantly made.
like MegaSquirt.com does.... its a free service, Mouser dont have that(yet). but they are fast and very cheap.
