EastCoastEJ22T Posted January 23, 2011 Share Posted January 23, 2011 Hello, I have recently sucessfully completed swapping a 1992 OBD1 Eg33 into a 1995 legacy. The car was running perfectly with no cel's and pulled like a freight train. I had it out for some rally-x practice and coated the bay with muck/ice so I decided to de-grease and pressure wash the bay the other morning. Covered the alt and igniter to keep them from getting wet. Ran/drove the car afterwards for 10min and she worked perfectly. Left it for the day and tried to fire her up after dinner and she won't start. Cranks over fine, lots of fuel and the pump is running. But it is getting no spark. I pulled the alternator to check the Crank sensor's (svx has two) and found some cracked wiring at the connectors. I pulled and rewired the connectors, and she started briefly and stalled out again. I then pulled both crank sensors, cleaned them up and re-installed but she will not fire at all now. My guess is that the Crank sensors were on the way out, and the removal process killed them completely. The cylinder shaped body of sensor seems loose from the connector. Does anyone know how to test the crank/cam position sensors, SVX replacements are big bucks. I ordered some good used replacements from a person on SVXnet but would like to test the old ones if possible while I wait for the replacements. Any input or advice is appreciated, Cheers, Ian Link to comment Share on other sites More sharing options...
Cougar Posted January 23, 2011 Share Posted January 23, 2011 I suspect the sensors may be ok. There may be an issue with the power to the ignition system. The first thing to check is the fuses if you haven't done that already. If they are all ok then check for power getting to the ignition coil. Check the ECU codes would be a good thing to do also on the hunt for clues to solve the trouble. Nice job on the conversion BTW. Link to comment Share on other sites More sharing options...
EastCoastEJ22T Posted January 23, 2011 Author Share Posted January 23, 2011 All the fuses are good, there is power going into and signals going out off the ECU. I am getting these two codes. 11 ........ Crank Angle Sensor No. 1 ......... No Reference Signal 29 ........ Crank Angle Sensor No. 2 ................... No Signal Must be the sensors, or possibly the harness. Link to comment Share on other sites More sharing options...
Cougar Posted January 23, 2011 Share Posted January 23, 2011 (edited) In this case the crank sensor does appear to be the trouble. Make sure the signal wire from the sensor to the ECU is ok first. If that checks out ok then I would suggest replacing the sensor and the engine should fire up. Edited January 23, 2011 by Cougar Link to comment Share on other sites More sharing options...
lesstutrey Posted January 24, 2011 Share Posted January 24, 2011 i like the swap, and your name, as it is mine too Sorry, got no help to offer though... Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 25, 2011 Share Posted January 25, 2011 Hell yes! I bet that thing's a beast! Test the sensors with an analog meter. Look for the needle to jump in a pattern as the engine cranks. The older 4 cyls just have a simple 1,1-2 , 1,1-2 pattern. Suspect the 6 would have similar.

ShawnW Posted January 25, 2011 Share Posted January 25, 2011 When you performed the wiring repair did you verify that you didnt get any shielding for the wire touching the actual wire? Its sort of like Coax cable. Link to comment Share on other sites More sharing options...
EastCoastEJ22T Posted January 25, 2011 Author Share Posted January 25, 2011 Yeah it is an absolute monster. These Eg33's are really amazing engines. -non-interferance - 10.0:1 compression - 230hp/228tq -6800rpm redline -dual throttle bodies -coil on plug It will break traction shifting to 2nd, and thats with an old 4:11 4eat. Top speed is unknown, because it just keeps on pulling..... past any speed I care to travel on winter roads. Unfortunately I am swamped with work at the momment and temps outside are in the -30C with the wind chill. I ordered a bunch of used parts up on the "SVXnet". Should be receiving a ECU-MAF-Crank sensors and igniter sometime in the next few days. I will check some pins and voltages, hopefully its something simple. The next auto-X is Feb6th so it will be back on the road by then. I will shoot a video and post it up when I get the bugs worked out again.

EastCoastEJ22T Posted January 25, 2011 Author Share Posted January 25, 2011 When you performed the wiring repair did you verify that you didnt get any shielding for the wire touching the actual wire? Its sort of like Coax cable. The shielding is pulled back 1/2" from where I did the splice. It could be a break/crack further up under the intake manifold. The wiring is very brittle and I think i was better off leaving it alone, but whats done is done. I have a spare Eg33 that I may strip the engine harness from and re-wire in the future. Thankfully this is not my 1st or 2nd mode of transport, she is really just a toy for thrashing on at the auto-x events. Link to comment Share on other sites More sharing options...
Cougar Posted January 25, 2011 Share Posted January 25, 2011 Check the continuity of the wire between the sensor connector and the ECU to make sure it is ok. Check the resistance between it and the shield wire also if you can to verify they aren't shorted together. If those tests show good then the trouble is most likely with the sensor output.

EastCoastEJ22T Posted January 27, 2011 Author Share Posted January 27, 2011 She is fixed and up and running again. Both Crank Sensor #1 & #2 were toast. I would say they were cracked from age and on there way out and the ingress of water from the pressure washing took them out completely. Also found some cracks in the wiring, so I re-pinned and wired up the connectors. I fixed the wiring and tried out the old sensors, but she still would not fire up. Changed out the sensors and she runs like a top. Thanks for all the help and tips. Cheers, Ian Link to comment Share on other sites More sharing options...
Cougar Posted January 27, 2011 Share Posted January 27, 2011 That's very good news Ian. Glad to hear you got it going and thanks for the update. Link to comment Share on other sites More sharing options...
