I've searched the internet high and low for info on this but found nothing, all I can find is NA dizzies and even then no specific model number for just the pick up coils
![](./images/smilies/spacer.gif)
One of the pick up coils in my SC dizzy is showing infinite resistance/dead and the car won't start
![](./images/smilies/spacer.gif)
(having ruled out/replaced pretty much everything else including cleaning up grounds).
![](./images/smilies/spacer.gif)
I also tested the wire from connector to close to the pickup and it was ok(not broken) so have to assume the coil itself and its windings are gone.
![](./images/smilies/spacer.gif)
I can't find anywhere that actually says why the SC has 3 pick ups
![](./images/smilies/spacer.gif)
(NE,G1 and G2) vs the NAs 2.
![](./images/smilies/spacer.gif)
It's not a 6 cyl of course so wondered if it was a separate one for the timing choice fitted to some
![](./images/smilies/spacer.gif)
(US?) SCs for fuel type, or is it because the ECU converts 1 360 revolution to 2 so needs 2 signals per rev?

My GZE is JDM and I've gone in many circles this past month
![](./images/smilies/spacer.gif)
- can't even buy a new SC distributor
![](./images/smilies/spacer.gif)
(and were super expensive when you could looking at one old discontinued toyota parts page
![](./images/smilies/spacer.gif)
$600) but can't find the pickups either to just fit inside myself as the dizzy itself is good.
![](./images/smilies/spacer.gif)
This is quite low mileage 60k if that and I've had it nearly 20 years
![](./images/smilies/spacer.gif)
(the engine at least
![](./images/smilies/spacer.gif)
- it's gone from a Japanese import SC to 2 NA's
![](./images/smilies/spacer.gif)
- one rusted out
![](./images/smilies/spacer.gif)
- so it's currently in a conversion and yeah it used to start and run good till left in my garage for a few months without starting).
![](./images/smilies/spacer.gif)
Yes to every q you may ask
![](./images/smilies/spacer.gif)
(from brand new battery to new coil/ignitor/grounds check/dizzycap/rotor arm/new spark plugs, fuel OK drained old fuel and put brand new in
![](./images/smilies/spacer.gif)
- pump working
![](./images/smilies/spacer.gif)
- no spark! Though once testing I did get spark
![](./images/smilies/spacer.gif)
(with a tester so wouldn't know if would start up cos had the EFI fuse out for test)
![](./images/smilies/spacer.gif)
- next day tested again with tester NO SPARK! damaged wiring could be something else in the loom but It's been treated well and I've checked most points with a multimeter back to ecu etc.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
) it's driven me crazy cos it's a good engine and car but has spluttered to life only twice
![](./images/smilies/spacer.gif)
(then cut out again asap) and then just cranks.
![](./images/smilies/spacer.gif)
Intermittent spark
![](./images/smilies/spacer.gif)
(though does spark when switching back to run for 2 sparks) should be attributable to this one dead G2 pick up right?
![](./images/smilies/spacer.gif)
FTR I've got a ton of spares from my previous 2 MR2s
![](./images/smilies/spacer.gif)
(all Dark Blue Pearl 88/89) not that that's important
![Wink ;)](./images/smilies/icon_wink.gif)
but I've got 3 ignition coils with ignitor packs and swapped them all on to rule that out
![](./images/smilies/spacer.gif)
- surely all 3 couldn't be dead
![](./images/smilies/spacer.gif)
(Coils checked out for resistance test and power is at the coil in
![](./images/smilies/spacer.gif)
'run'
![](./images/smilies/spacer.gif)
(12.4v) and 9.6v while cranking.
![](./images/smilies/spacer.gif)
Battery is
a BRAND NEW Yuasa YBX 60ah/450a and it has NO problem cranking
![](./images/smilies/spacer.gif)
(very strong).
![](./images/smilies/spacer.gif)
If it's not the one
![](./images/smilies/spacer.gif)
'dead' dizzy pick up coil, then my ECU must be damaged?
![](./images/smilies/spacer.gif)
(or maybe the loom/wiring)
![](./images/smilies/spacer.gif)
- I did notice some moisture inside the ecu from a slight leak but not sure if it's damaged any chips
![](./images/smilies/spacer.gif)
So basically I'm looking to find/buy/replace one pickup in the distrubtor but can't find them anywhere in the world it seems.
![](./images/smilies/spacer.gif)
Even some mR2 specialists have scratched their heads.
![](./images/smilies/spacer.gif)
I can find NA dizzys new and used no problem
![](./images/smilies/spacer.gif)
(but not individual pick up coils) but can't tell if they are the same pick-up
![](./images/smilies/spacer.gif)
(just different wiring and only one
![](./images/smilies/spacer.gif)
'g') and could be retro fitted somehow? Is there a part number for the OEM Pickups on the 88 4agze?
![](./images/smilies/spacer.gif)
I've also got the BGB and done pretty much everything in there to test.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
it's not much help with THIS issue as it just says replace dizzy
![](./images/smilies/spacer.gif)
(but you can't actually buy them).
![](./images/smilies/spacer.gif)
I did the
![](./images/smilies/spacer.gif)
(two) na
![](./images/smilies/spacer.gif)
> SC conversions/engine swaps myself so know they were done right, and as said it would start first time everytime for 10 years
![](./images/smilies/spacer.gif)
(inc many years just in the garage while I didn't need it) right up until I had to move house and it wouldn't start
![](./images/smilies/spacer.gif)
Thanks for any info.

Weird, the spark plug tester started working, possibly cos I had the EFI fuse in this time
![Wink ;)](./images/smilies/icon_wink.gif)
but no start.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
so looks like I'll be checking fuel again
![](./images/smilies/spacer.gif)
(but still the dead pick up is confusing me both what it's used for and if it would start up with just one pick up working but run terribly)
![](./images/smilies/spacer.gif)
Lastly, if I had a vacuum leak from intercooler
![](./images/smilies/spacer.gif)
(rubber pipe basically split in half and taped up) would that stop it starting.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
I think it would at least catch.
![](./images/smilies/spacer.gif)
Have had the IC pop off before at over 100
![](./images/smilies/spacer.gif)
(test track
![](./images/smilies/spacer.gif)
) and died straight away.
