Hi Jim,

I've had a look for you and YES, I can get you a genuine Nissan power transistor. I will pm you later with the prices, the availability date and the postage costs. Hope this helps.

ECU's also tested okay today :-)

I have ordered the transistor from RockAuto in the USA, it had a five day delivery which is excellent .... price US$ 115.70

Thanks to Ady who was very helpful, the Nissan part which would have been my first choice was unfortunately on back order which meant that there would be a six week delay.

Great news about the ECU, thanks for testing it :D , AJL I'll send you a PM.

Hi All, The ECU and Power Transistor arrived today, thanks to Andy and Jim for the ECU.

There is no good news I am afraid, stuck them in and still no spark - physically checking at the lead from the coil. Checked the coil resistances again and they are fine. Also bypassed my immobiliser and proved that was OK. Checked the voltages going to the distributor (0.5V x 2, 12V and Ground) and they were spot on. Also checked the HT lead resistance from the coil to the distributor and it checked out fine (grasping a straws a bit). The only other "common denominator" I can think of is the distributor LED and optical sensor on the ignition side (I checked that the fuel injector solenoids fired before by taking out the distributor and rotating it). Has anyone any ideas on how I can check the distributor ignition side?

If anyone has any further checks that I can do, I now have a scope multimeter (which I still have to get familiar with) so any checks using that will be most welcome as well.

Interestingly the ECU diagnostics were identical to those previously described.

I guess the positive I have is that I now have a spare ECU :)

I'll keep plodding on as well and hopefully can regenerate some grey matter dreaming about the fault overnight :idea:

ive written this before somewhere on here, but remove the distrib, turn on ignition and spin the dizzy shaft with your fingers. You should hear the injectors clicking. If you don't, its highly likely its dizzy.
if they do and you get no spark, trace the connections to the power transisitor from loom, connect multimeter and again spin the shaft. If you don't get any flickers, its highly likely the dizzy.

the attached was written by a friend and one time SS1 turbo owner and more importantly electrickery uber-geek, hopefully help

if having done the attached test, you are convinced the dizzy is ok, then I suggest tracing back the 4 wires from the dizzy plug along the chassis rail (passed the glowing turbo! great thinking Reliant...) and then up past the heater blower and through the bulkhead and into the cabin. The loom disappears behind/above the heater matrix box and re-appears bu the door pillar and the into the ecu plugs. If you remove the speaker, you can pop the loom and plugs through so at least you don't need to be a 3 elbowed Tamworth midget (as those that built the cars were of course) and do a headstand in the footwell to be able to check the continuity of the leads from dizzy plug to ecu.

If you are not convinced the cables are 100%, id run 4 new wires and from ecu plug and re-route along wing top side and then down to the dizzy plug and try that, gotta be better than its life at Gas Mark 4 next to the turbo!!

Thanks Chris, I did the tests on the distributor off the car, injecting 12v on the positive and negative at the plug and checking the voltages with my scope multimeter at the green and white connectors.

The 90 deg output gave a pulse near the white spot whilst it was hard to define any voltage for the 1 deg points - all I could see was a change when spinning the dizzy as fast as I could by hand. The voltages though were very low level, what voltage is normally expected?

I went and had a chat with two auto electricians but both said that if the fuel injectors are firing the distributor optic side is OK. Mind you one did say that the voltages should be around 0.5v, mind you he may have been talking about the 0.5v coming from the ECU which is correct - not the dizzy only with a 12v supply.

Checking the voltage on the power transistor with the ignition on I get 12v at the collector and emitter which I think may mean that there is no signal from the ECU to switch the open collector. Hence perhaps there is a problem with one of the sensors that go to the ECU that will kill the signal from the ECU to the Transistor. Does anyone know which of the sensors actually will shut down the ignition to the engine?

Hi All, Been doing some more troubleshooting after getting my second wind on the SS1Ti.

I checked out the distributor again and used data from a couple of internet sites http://my.cardone.com/techdocs/PT%2031-0002.pdf (not exactly the same but worth trying) and http://www.cdxetextbook.com/electrical/ ... nsors.html which describe tests and the unit.

On checking the voltages at the distributor plug harness with everything connected and ignition on I get 5.0v on one terminal which goes to 0v when the injectors fire - this happens the 4 times as the dizzy is spun manually through the 360 deg. The other 360 slits signal just stays at 5.0v and does not switch - pointing to one of the two optical sensors failing I think (and hope).

I had a look at the sensor but the screws are sealed captive so I assume that the distributor is unserviceable - am I correct?

Looking for a replacement I have contacted Nissan here in Perth without success, so I would much appreciate it if anyone has any recommended supplier for the distributor in the UK.

Details I have on the dizzy are D4P83-06 6Y02 22100 21F01

Thanks, Jim

Im sure Jim K and possibly Ben Kenobe have removed the baseplate etc and cleaned the optical sensors, maybe they can offer details and whether successful?

im sure Aus got vehicles fitted with the CA18ET so used replacements should be available locally (I realise local is a relative term in Australia compared to little old blighty lol)

if not, I would try GW and QRG who may have the items from the receivership sale of Reliant or Ady, our tame Nissan guy, but I seem to remember them being £600-£700 GB a few years ago when a friend enquired.

I'm sure that all CA18ET's worldwide used the same distributor. The optical sensor inside it can always be removed for replacement, the screws securing it into the dizzy casting are accessed by unscrewing the screw in the central shaft and removing the optical pickup 360 degree disc.

If you're having trouble sourcing a replacement then look no further as you won't find a cheaper replacement sensor than this: http://www.ebay.co.uk/itm/130481397720? ... 26_rdc%3D1

It will work too! You might need to place a metal washer under the pickup disc to raise it up by 1mm to correct the disc's allignment, or you might not.(pattern parts eh). Either way it will work. :)

are you sure that crank position sensor would work? as mentioned previously in this thread, there are two sensors in the CA18ET dizzy.

I think from the list, its shows the CA18T which is the non-efi version so would only have the one optic eye.

potentially be raided for bits though?

Just checked and Nissan distributor 22100 21f01 is no longer availble from Nissan. Second hand or aftermarket only i'm afraid unless your lucky enough to find a new old stock one.

Standard Motor Parts LX-653 as shown in the link is universally listed as the correct Crank Position Sensor for the CA18ET on every parts compatibility list I've found. It also fits the 300ZX Turbo as shown in the link so is suitable for Turbo'd Nissan engines of the era. There's no such engine as a CA18T, it's a typo from the seller.

Search some parts sites for LX-653 compatibility and you'll see.

Here are two random ones;
