  1. Ignition relay powers pins 21,29 and 49. ECU receives unswitched power on 27. See page 46 section 2-7 of the ea82 manual here http://jdfinley.com/file-downloads/subaru-manuals/ Relay coil=Ignition relay control coil(inside the relay) Excessive ignition coil resistance results in weak or no spark.
  2. Yes,I consider the ignition relay misnamed.It does not power the coil. Your lack of power at the coil is not due to an ignition relay circuit fault,but,most likely shares a common cause. The ignition relay powers the ECU. There should be voltage on the relay coil w/the key on. Ignition coil sounds like a problem,but,that does not explain the lack of power.
  3. Losing any coolant? If not,then not to worry. Engines produce water w/they run.The vapour condenses and becomes visible w/it is cold out.
  4. SPFI? "Ignition" relay has nothing to do w/coil power. If you have power on BOTH sides of fuse 11,but none at coil +,then you have a wiring problem between the fuse and coil. Ditto for fuse 12 if you have no power on the ignition relay coil. If the fuses have power,ignition switch is OK. Sounds like a loose harness connector.
  5. Engine does the pumping for both.
  6. Outside temps do not have to be low to get carb icing. In fact,carb icing becomes LESS likely as outside temps drop below freezing. You may find ihis interesting.I did. https://www.casa.gov.au/sites/g/files/net351/f/_assets/main/pilots/download/carburettor_icing_chart.pdf The chart only applies to AVGAS. Carb icing will occour at even higher temps w/automobile gas because of its greater volatility.
  7. Look for RHB5 Plenty of choice. http://www.ebay.com/itm/IHI-RHB5-RHB51-RHB52-DAEWOO-HONDA-YANMAR-MY8-MY29-GY14-Turbo-Rebuild-Repair-Kit-/272030521599?hash=item3f564858ff:m:mF8iK67JFAGSDarJVgwOTAg&vxp=mtr#ht_2899wt_916
  8. $45 is going to be hard to beat. There is a good chance you could repair yours by replacing the worn out brushes(inspect them). https://www.rockauto.com/catalog/x,carcode,1267679,parttype,2424 You could likely source these locally. Or part # 49574 7601 at the Suby dealer.About $6.
  9. I think you can swap in an ea-81 disty w/internal ignitor fairly simply. Points are garbage. The tach "counts" the pulses generated by the transistor box,but,the lighting issues are unrelated
  10. Your year is different. Read historic codes by connecting the black "read memory" connectors. Green test mode connector must be disconnected. Both green and black should be disconnected for normal operation. They are located under the steering wheel or in the engine compartment.
  11. That one is 171 degrees. Click more info http://auto.detnex.com/autoparts/search/21200AA121/ Stock is 190 for 1984. Was part # 41753 7000,probably discontinued.
  12. Voltage. "looks good" is not good enough. Check for voltage on both sides of the fusible links and fuses before condemning the switch. If the lights are inoperative as well,check the wire from battery + to the fusible link box.
  13. Sounds like a bad ignition switch. The wire io the ECU provides a RPM signal.
  14. It is the FICD(fast idle control device) It opens a bypasses around the throttle plate when the AC is on in order to increase the idle speed.
  15. You need voltage at the coil before worrying about anything else. Check the fuse,fusible link and ignition switch.
  16. Fuel pump is supposed to stop w/test connector unplugged and engine stopped. Are you saying car won`t run w/o connector connected? There should be no codes w/engine running. The ECU lamp will flicker in response to the O2 sensor voltage though. I do not think EA-81T ECUs have a safe mode I have not tested that to be 100% sure. They only control fuel(not spark).
  17. Codes will show w/trouble is present whether the test connector is connected or not. 11 is normal w/stopped engine.Pretty sure 12 is too. 33 is not.It indicates a faulty coolant temperature sender or associated wiring. Green connector is not connected to the fuel pump,only the ECU. Pump should cycle off/on w/connected.
  18. NIGLUBE RX-2 is a red/orange high temperature lithium soap based grease. http://www.nippon-grease.co.jp/en/products/grease/g02.html I would use any of the rubber compatible silicon brake greases after making sure the NIGLUBE is cleaned away.
  19. FWIW,parts book lists 9 different EA-82 rads just in the 85-89 timeframe. 2 are for XTs. Most of the other differences seem to be auto/non and turbo/non. 87-88 4WDR california GL sedans have thier own part # for some reason.
  20. Ignition switch is a likely culprit. Your diagram is better than mine. Looks like you do not have a ballast resistor after all. Good luck.
  21. If there was no bleed,the solenoid would not be able to command the egr valve closed. Vacuum would be trapped,
  22. my factory manuals for early 85 86 claims EGR not operational until at op temp
