  1. That's the Lada now done 1200 miles with the SR20DE and no issues, other than it seems to be pretty thirsty. Probably because I like the three stage induction noise as you accelerate! Thanks again for the help.
  2. Best tip is probably to unwrap the harness between the ecu and the plug you're working from. It makes it really simple to follow the wires as once you get started you can soon get jumbled up. Eight wires doesn't sound like much but there are so many other ones too, often with similar or the same colours, some joining into other things too. If you can see the physical wires it's so much simpler and will save you loads of time.
  3. Thanks for clearing that up. I guess it's only the fwd models that would have an engine fan controled by the ecu then. I have no space for the viscous fan and wont be running the air conditioning so will just run a separate fan controller so the electric fan control is directly related to the engine temperature.
  4. Thanks very much for the guide and the help available on here. If anyone is starting this thread from the end then some very basic advice would be not to over think it, you don't actually need to know why you're doing everything. Reading through the thread can be confusing at first. The most important thing in hindsight is not to cut any wires unless they're at a plug. If joining anywhere else in the loom just splice into the wire as it could be connected to something else further up. Does anyone know if the fan is controlled by the ecu in the SR20DE (S14)? I found some information saying that the relay was triggered by pin 9 on the ECU but the pinout diagram that seems right for my car has pin 9 as being the AC cutout relay. There is no mention of an engine fan. The car did have an electric fan as well as the viscous one.
  5. Didn't find it. All my wires were originally wrapped together at the bulkhead. I don't think I have coil packs, just a distributor which seems to run off eight wires in the main engine loom. It's an SR20DE, non turbo from around 1993/4.
  6. Thanks hosestop@msn.com. Found the problem finally and it was simple, and my fault. I'd cut a wire that branched into another feed further up the loom. Reconnected it and engine fired first time.
  7. Have checked and double checked my wires (so has someone with a bit more of a clue) and the car still wont start. It's getting power to the distributor but there are no signals coming back from it to the ecu. Is this likely to be a problem with the wiring or the distributor itself? The engine ran fine before it was pulled from the 200SX, it's been around four years but it's been dry stored. Distributor contacts and rotor arm have been cleaned up. Have run an extra earth to the head just incase. The standard blue relay (ECU relay) in the wiring when all the wires are traced out doesn't seem to be needed as one of the new relays is doing the same job. Any ideas?
  8. I have the wiring 'done' but have obviously managed to get something wrong. All my relays click, the fuel pump primes and the starter turns the engine but it doesn't catch. I'm getting plenty of fuel fed up to the engine but don't seem to be getting fuel into the cylinders or a spark (spark plugs completely dry and no heat at all in plug tip after cranking) so guessing something wrong at a pretty basic level. My first thought is that I haven't located the injector + wire. Have gone back to the harness and the wire I imagine to be the injector+ one is actually black with a red tracer (not solid red as I put in last post) This has 12v with the ignition on. I've labelled it 'A' in the picture. The part labelled B is what I think are the earth wires for the loom so I've just screwed them to the engine which is earthed to the body. I've assumed that since the ecu has switched on the fuel pump that it must be getting power. Is this likely to be correct? The orange with blue wire is definitely connected to the starter solenoid wire. I have my voltmeter at the ready, what should I check first please?
  9. Pretty sure I've found it. There's a fairly thick solid red wire going into the plug that connects to the injectors wiring harness. Must be it. Traces back to a different plug on the loom but that makes sense as the ecu wont need to 'see' that power. This is my first encounter with efi so a steep learning curve.
  10. I'm still being really thick here. The most annoying thing is that I'm sure it should be so simple. Where it says injector + on the diagram am I looking for four wires (one per injector) or is there one wire feeds all of them? All the other wires have colours beside them. From the ECCS wiring harness pinout I have pin number 5 goes to ECCS relay and pin 46 goes to ECCS backup power. Where would the injectors normally get their power from in the 200SX?
  11. Looking forward to getting this running. Really need it back on the road for the middle of next month. Should be double the power of the standard 1.5 Lada engine.
  12. Another question please, thanks and sorry! on the SR20DE non turbo diagram it says "injector +" as part of the stuff to connect to the fused ignition power. Is this a wire that has to be found on the engine or is it in the loom/ on a plug. Sorry if I've missed it in a previous post.
  13. Have pulled the engine out again, try and get a better look down the side as there seem to be quite a few wires for the alternator and starter that I'll need to work out (ask other people about!) I googled IACV and Air Regulator for the SR20DE but not sure I can see them on mine. I found this yellow w black wire. Is this my air regulator? It doesn't look like the pictures I found but the wire's the right colour and it's in the air intake! Does anyone know where the IACV is and what it looks like as I still have this brown wire to find. So many pictures and diagrams have been lost from various threads thanks to photobucket that it's getting really frustrating trying to find pictures of what I need.
  14. I've re-read this thread about five times now and it's making more sense every time. I've just passed the post saying don't cut any ecu wires, take them from white plug (plug 2 below). I've obviously cut the ecu wires already. Doh! Does it make a difference where they come from or should I reconnect them and use the wires at the white plug? That way I could wire my relays into the other side of the plug and it would be easier to get all wiring through the hole in bulkhead. The white plug also has a solid brown wire (fairly thick) and an extra yellow w/black so presumably these are the ones I couldn't find when I was working from ecu plug. Does anyone know what this plug 2 is called so I can search for a pin out diagram please. Sure I've seen one somewhere. Thanks!
  15. I can guess why! :-) Thanks for getting back to me. Just need to work out what an air regulator and an IACV look like and I should find the ends of those wires....
