Didn't get a chance to report last night, but heres where I got to. It Started and ran :)
After spending hours Friday night and Saturday morning reading more threads about CIS etc, printed testing precedures for various parts and armed with Tony's list of things to check I tackled it Saturday afternoon. Put Battery on charge Checked all Fues's. Added 20lts of Fuel.... can't hurt. Removed Fuel cap. I read somewhere that it could possibly be air locked and I think I put my fuel tank breather together after I first had it running. Check WUR identification and it seems I have the wrong one for my engine type 930/10. My WUR # is a 0438 140 112 not 089 Tested my WUR 0hms reading which was 39 or 45 depending on which way around you put the pins on the plug. My electrical abilities are poor so I don't hold a lot of hope that I'm doing it 100% correctly. My TTV was disconnected, connected that. Then I started fuel leak tests of the line after disconnecting from injectors, with FP running is was dribling out all of them! Connected Injectors and was dripping from some and squirting out of a couple. This is not good!, thinking my FD is cactus. I remember Tony mentioing that the little 3mm Allen key adjuster shouldn't be used to get a engine running but for later tuning. The way it worked in my head was perhaps this is too Rich and constantly letting fuel in when FP is running. I turned it anti-clockwise almost 2 turns until I had no Fuel dripping from the fuel lines whilst FP is running. Noticed a small weep from bottom connection of Fuel Accumulator so gave that a tighten. Reconnected all Fuel lines, injectors, removed all tools. Didn't want to run the FP for long before starting just in case it decided to leak fuel in to pistons for some reason..., turned the key and cranked to start and it fired straight up and idled well albeit a little high in my opinion but rev counter not operating so didn't fiddle. So what fixed it? could have been one thing or all things I don't know yet but I will be able to elimate a few things when I get more time to do so. At the moment just happy it started again. To all those that offered suggestions and helped point me in the right direction, THANK YOU couldn't have done it without your help. Brent |
Thanks Tony! also replied your PM.
Great offer... I'm just nervous to swap it out just yet as I have it running now and need to do some other testing once it can drive. It operated fine before I purchased the engine so not sure of why this is wrong. I may look at purchasing a 089 from you in due course so I can at least check and have the correct type for my engine.

For your peace of mind.........
Brent,
You probably don't know me and that's OK. What I am offering you is an opportunity to have a calibrated and rebuilt WUR-089 that you could use and test in your car. Hundreds of people that borrowed either a WUR or FD gave me a substantial refundable deposit via PayPal. And I am now breaking my own protocol just to extend help to you. My wife is leaving for Australia next week and be back home after 8 weeks. She could mail the WUR-089 from Sydney to NZ if you decide to accept a swap. The WUR you have now will make your engine start and run like most WUR's but you will not have the optimum performance from WUR-112. Contact people in NZ or AUS or Europe with '81-'83 SC RoW and inquire about their WUR's. If you are not completely satisfied with the performance of my WUR-089, simply send it back to Sydney no question asked and I will have the core returned to you from Sydney. Your window of opportunity is starting today till end of August. Wish you the best. Thanks. Tony |
Tony,
It's not that at all, I have no issue with that. So many good reviews on the board and you have been soooo helpful on my thread issue over the last few days as well. I think I will take up your offer of a exchange WUR, although mine seems to be ok it will not be optimum at some points so may as well get it right. Lets sort the details out on messages.

Let's close the deal.......
Brent,
Let us put this on record. Please post the heater resistance (Ohms) again and vacuum test both the side and top ports using a hand vacuum pump. Post the data. And I will have the package iin my wife's luggage. Thanks. Tony |
Update.......
Brent,
My wife arrived in Sydney 3 days ago and got a phone call from her asking me what to do with the WUR-089. Were you able to measure the heater resistance value and test the vacuum? In case you changed your mind about the swap just let me know. There is someone from OZ interested to get it. Thanks. Tony |
Hi Tony,
Yes still intend to do exchange as discussed. My Electrician is slowing the process at the moment, however as mentioned it could be 2-4 weeks before I'm ready to send. Will post test results when I can get the information you require. Regards Brent Quote:

Your engine could never run properly with a -112 WUR. The -112 WUR is from a Euro 930 and will only enrich under boost, which your engine will never see. Also the -112 is tuned for 6.0bar system pressure and has a slower cold warm up cycle than required for the SC. The '73 CIS has no vacuum enrichment at all and used a throttle switch. The wiring harness would not be the same as an '81. I would check all of these things. Having the same CCP and WCP means the WUR is not receiving electricity so the pressure will never decrease and engine will flood out as it warms.

Great info!
On track to swap out my WUR for the correct one with Tony. Win win for both I'm thinking. Thank you RarlyL8 Quote:

Tony,
Have got the info you requested. 0hms resistance yesterday was 26.4 0hms, temp was 4.2 deg celcius... yes COLD. The side port was .8bar and holding Top port seemed to be .5bar and leaked away? I went to Four places to find a vacuum pump or someone that knew what to do... we have no idea what the values should be so not sure if done correctly or if the pump was working correctly. All I do know is that it comes off a car that does run. Please confirm ASAP if you're still happy to proceed with exchange and I will courier to Australia as discussed. Regards Brent Quote:

WUR swap.......
Brent,
I have the WUR waiting in Sydney, Australia since last week. Send your WUR to the address I gave you earlier and my wife will send the WUR-089 to Christchurch, NZ. Thanks. Tony |
Hi All,
Have been making some progress to resolving my issues, I took up the offer from Tony to exchange to the correct WUR for my model engine, he also kindly offered lifetime CIS support which is great :) That just arrived on Friday, I installed Saturday arvo and 2nd crank of the key it fired into life, all was well for about 1 minute then rev's started dropping and it was leaning out, gave it some revs which would keep it running but as it warmed up leaned out further and shut down. I was forced into sorting out a vacuum leak test system... read a few posts and Tony has given me some ideas. In reality very few of us have the required items to make this work, if you do have a compressor its likely to be 70-170 PSi, unlikely to have a regulator that you can wind back enough for the required low pressure of under 10 PSI. I had googled low pressure pumps and come across an aquatic tank pump for blowing bubbles for Fish, found one that pumped 192 l/hr at 2.3 PSI, of course this was in USA so needed to source one locally. Sunday morning I went to a local pet shop and brought the following pump... approx $15 USD. http://forums.pelicanparts.com/uploa...1501997437.jpg Plumbed it up into the brake booster inlet and blocked up the rest of the holes once the Air box Pope was removed and worked a treat! http://forums.pelicanparts.com/uploa...1501997538.jpg http://forums.pelicanparts.com/uploa...1501997560.jpg The pump as two speeds, low and high, ran on high to quickly get the pressure up and inflate the glove then switched to Low, sprayed away with my detergent/ water spray bottle and listened and looked for leaks, found one at the base of the pop off valve. http://forums.pelicanparts.com/uploa...1501997663.jpg I have cleaned it down and filled as best I could with some JB Weld, leaving overnight to cure and will re check again. Does this look enough to cause the issue I'm having? Getting the Pope off and relevant hoses with engine in the car is a PITA, not wanting to do that many times if I can avoid it. Any suggestions would be helpful... have emailed our CIS guru Tony for his continuing support to get this running smooth. Brent |

Agree I should inspect those also.
If I had tested with the cover on I wouldn't have found this leak, will concentrate on this area first then I can add cover and see if there is still pressure loss. Brent |
So, JB weld held good and I couldn't find any other leaks. Obviously with it in the car does make it impossible to check everywhere. After turning my pump off it did seem to keep the glove inflated on the throttle body pretty good but hard to say how much loss I got.
Performed Fuel tests with guages and all read low compared to the specs for my 089 WUR, not sure if this is because of my ambient temp being 15deg? Started the engine and it fired first time, idled up nice and dropped as temp came in, didn't lean out as like previous time so maybe that leak was enough to cause the problem. I adjusted idle up a little and with a few blips everything was good. Removed cap to check oil and it died!, tried restarting and it wouldn't start warm, pressure was 2.5 bar. Left it a hour or so while doing other jobs and after 2nd attempt it did start with a little help from throttle, adjusted the idle a bit more to around 850rpm and when warm again shut off and restarted fine so fingers crossed! Hope to get it out for a drive tomorrow for the first time and will see if any other symptons show up. Brent |
Fuel pressure........
Brent,
I got your PM. Measure the residual pressure: After the FP stopped After 10 mins. After 20 mins. System pressure = 4.6 bar (66.7 psi)..........spec. (66~75 psi.). Set it to 72 psi. Control pressure = 1.05 bar. Is this a typo? Please verify. Warm con. press = 2.7 bar (after 3.5 mins. Vac hose connected). Too low. Is the vacuum hose connected to the side port of theWUR? Is the vacuum hose getting vacuum at idle? Do you have a hand vacuum pump? What is your cold idle engine RPM? Is AAR working? Be patient and we will sort this engine very soon. Keep us posted. Tony |
Just to update other readers Tony and I have been exchaning emails to get this issue resolved.
Have removed the AAR and tested with 12v and is working fine. I pulled apart the WUR as it was reading lower than we would like and although Tony had reconditioned it he wasn't happy with readings. Although after inspection and quering the numbers it was spot on but we had overlooked the cold ambient temp I'm dealing here in my winter so all was good there for my control pressure. My system pressure was low at around 66.7 PSI, so I removed the plunger from the FD and found and made some shims to increase the System pressure, with the various washers/shims I had I could get either 69 or 73 PSI so currently set at 73 PSI. I have just received a Vacuum hand guage to check some other items that need testing. I have had a variety of mixed cold and warm starts, rough running, lack of power, black oily substance out exhaust etc and then the day later it seemed to be running pretty good. I'm yet to set the CO with a proper gas analyzer which I hope to do in a few days. I wonder if my warm control pressure is a little low at 49PSI with the current mixture so depending on how that test goes where that ends up. Will update again after some more vacuum tests, CO adjustments and Tony returns from vacation to offer some more guidance. Brent Quote:
