MJLamberson Posted November 19, 2008 Share Posted November 19, 2008 Doing the turbo swap wiring, got everything working good except spark, heres whats up: When I had the coil wire off the coil so I could see if it was sparking, it would only create a spark for a split second and then stop, I took the positive off the coil and put it directly to the battery with the same results, it woul spark when the wire touched the battery, but only once and never again untill it was removed from the power then touched the battery again... whats up with this? its beyond me. ANY advice would be great, and if you need to know anything else let me know, thanks. -Michael Quote Link to comment Share on other sites More sharing options...
big-phil Posted November 19, 2008 Share Posted November 19, 2008 I think, if you put the 12+ of the coil to the batt. it will only spark once. Your dizzy turns it on/off as needed for each cylinder. As far as almost no spark when cranking do you have the external CAS? (1981 turbo motor) or is it in the dizzy (1982-1983 motor) I had the external CAS that bit the dust on me, and had the optical pick up in the dizzy poop the bed also. Once there gone, no spark.

MJLamberson Posted November 19, 2008 Author Share Posted November 19, 2008 The CAS is on the dizzy, harness is from an 83 Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 19, 2008 Author Share Posted November 19, 2008 This may sound like a stupid question to some, but should all of the stock ignition stuff that is under the dash on the passenger side come out first? is there anyway both systems are being powered and thats why it isnt working?

big-phil Posted November 19, 2008 Share Posted November 19, 2008 Mine was all there after I swapped to the stock l28et harness. Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 19, 2008 Author Share Posted November 19, 2008 Does the ECU itself have to be grounded in order for the ignitor to work? right now mines just sitting on the floor plan Quote Link to comment Share on other sites More sharing options...
Swervey McZCar Posted November 19, 2008 Share Posted November 19, 2008 Is this on your 77 or an S30 in general? Sounds like that has already been done in your profile. Probably doesn't apply, but if you use the body harness (rather than running wires from coil straight to the ignition switch) in an S130 you must swap/reverse the wires going to the ignitor. They are exactly backwards. Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 19, 2008 Author Share Posted November 19, 2008 This is an s30, My sig does not apply, I had the car running on boost with the NA EFI but it ran like crap basicaly. Quote Link to comment Share on other sites More sharing options...
loy Posted November 19, 2008 Share Posted November 19, 2008 When I did my L28et swap earlier this year, I also had the problem of no spark. It turned out that I had wired an incorrect switched power, "acc" instead of an "ign" , wire to the ign wire on the efi relay. Hope it'll help. Which wiring did you follow? My ecu is sitting on my floor as well. Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 19, 2008 Author Share Posted November 19, 2008 I just noticed I dont have a wire going from plug 2 to my starter/ignition switch.... would that be causing my problem? where on the starter and I supposed to hook that up to? EDIT: I should probably mention that right now my starter isnt hooked up to my ignition switch, when I converted the car from auto to manual I didnt know about the neutral start switch so I just put in a button from positive to the soleniod. I dont see how this would affect anything but Im throwing it out there just in case. Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted November 19, 2008 Share Posted November 19, 2008 I think, if you put the 12+ of the coil to the batt. it will only spark once. Your dizzy turns it on/off as needed for each cylinder. Yes, this is the way the coils work (in simplified form). It sounds like the coil is good, and that is as far as I can help.

loy Posted November 20, 2008 Share Posted November 20, 2008 I'm guessing the ecu is also from an 83, Does the green led turn on in the ecu when you turn on the ignition? Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 20, 2008 Author Share Posted November 20, 2008 Yeah the green lite turns on. Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 20, 2008 Author Share Posted November 20, 2008 Also just realized that my coil is getting very hot... is that a clue maybe? Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 20, 2008 Author Share Posted November 20, 2008 This just in, the green on the ECU shuts OFF during cranking... normal or causing my problem/ what is the cause of this? EDIT: the light is turning off during cranking but power is still going to the coil, that just confirmed Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 21, 2008 Author Share Posted November 21, 2008 So when Im trying to crank the engine over, nothing happens, but as soon as I move the key from the on/start position to the off position it gives me a spark... huh? Please help my car has been down for to long. Quote Link to comment Share on other sites More sharing options...
Swervey McZCar Posted November 22, 2008 Share Posted November 22, 2008 Try taking the blue wire off the negative side of the coil. The wire that sends signal to the tach. You can undo it from the coil or at the resistor under the dash. Sounds like it is a dead ground. Quote Link to comment Share on other sites More sharing options...
Swervey McZCar Posted November 22, 2008 Share Posted November 22, 2008 Oh yeah. The light on the ECU comes on for a moment and then goes off during cranking. After it cranks, it will flicker when it processes the signal from the O2 sensor above 2000rpm. Quote Link to comment Share on other sites More sharing options...
MJLamberson Posted November 22, 2008 Author Share Posted November 22, 2008 How can I test my ignitor? it was said to be good, and looks like new, but Im thinking I need to test it. Quote Link to comment Share on other sites More sharing options...
