Sonicfrog Posted January 21, 2014 Share Posted January 21, 2014 I've replaced the disty, coil, cleaned the battery terminals, and yet, when it's cold in the morning, the car just won't start. It doesn't seem to be producing a spark. When the weather gets just a little warmer.... It turns right over.And just now, twenty mninutes after it failed to start, it turned right over.This one has me a bit stumped.I'll probably replace the ingition switch.Is there an ignition relay that could be a problem????Any ideas?

naru Posted January 21, 2014 Share Posted January 21, 2014 Is it having trouble turning over or starting? Turning over problems are battery,wire,or starter related, Check to see if spark is actually absent w/cold. If so,Check to see if coil has 12V on coil -,w/key on. Check plug/coil wire cold resistance. Despite the name,ignition relays do not have anything to do w/the ignition, Link to comment Share on other sites More sharing options...
ivans imports Posted January 21, 2014 Share Posted January 21, 2014 Check the ohms of plugwires / coil wire if to high will arc at coil and no spark to cap the old 78 wagon I just bought had this problem was just snaping from coil wire back to coil +post Link to comment Share on other sites More sharing options...
Sonicfrog Posted January 21, 2014 Author Share Posted January 21, 2014 Oh... I did put relay on the starter.I am getting 12 volts to the positive side of the coil. I tested the resistance of the coil, and that is right within the specs. I have put new eyelets on the wires connecting to the coil. When I test for spark, I have a wire with an alligator clip that I attach to the coil tower and run it into the cab where I am when trying to start the car. When it's sparking it ha a nice good arc. When not... Nothing.Right now, I just tested it, and it's sparking gangbusters. Link to comment Share on other sites More sharing options...
RustyBrat Posted January 21, 2014 Share Posted January 21, 2014 Electrical ghosts are the worst... Trace wires and look for shorts i guess Link to comment Share on other sites More sharing options...
Sonicfrog Posted January 21, 2014 Author Share Posted January 21, 2014 (edited) Electrical ghosts are the worst... Trace wires and look for shorts i guess Yeah... Those guys are nasty! How come there aren't any of those fancy-schnancy bits of ghost detecting equipment on the Ghost-Chaser shows that will detect those???

turbosubarubrat Posted January 22, 2014 Share Posted January 22, 2014 I've heard moister in the cap will make it not spark and reading how its only in the morning makes me think its a possibility. Link to comment Share on other sites More sharing options...

SubieBrat Posted January 25, 2014 Share Posted January 25, 2014 My 85 did close to same thing on cold days. would start until it warmed and would run low on amps and quite cranking. ended up being a shot battery. I would say take it to O'rielly's, autozone, just somewhere that you can get the battery tested and see if it drained so badly it wont hold enough of a charge to start when cold Link to comment Share on other sites More sharing options...
Sonicfrog Posted January 26, 2014 Author Share Posted January 26, 2014 Think we narrowed it down to the ignition switch. One morning, in frustration, I hit the steering console with my fist, then it started up. We have a switch on order from Rock Auto. Should be here in the next couple of days. 1 Link to comment Share on other sites More sharing options...
SubieBrat Posted January 31, 2014 Share Posted January 31, 2014 Can you let me know how the wire work on it and which one you bought? ive been trying to find a place to by a decent ignition switch Link to comment Share on other sites More sharing options...
