OBS0LETE
Low Mileage
Hey all,
Have a 1987 Yugo that I'm trying to revive. I haven't played around with Fiats in years, so I'm a little hazy on what's what. Long story short, picked this car up for scrap value ($150) from an older lady that's owned it since 1989. Someone told her the timing belt had broken and it needed it's head pulled. Those are the pretenses I bought the car under. Turns out its timing belt is just fine, but we have a no spark scenario. First thing I thought was the ignition module had failed. Replaced the original bosch module, no luck. Got out the multimeter and had a poke around at the wiring at the coil, both wires on (+) had 12ish volts with key on, ground wire from ICM looks to be intact, all wiring looks good. Tested coil in my Saab 900, worked fine. Borrowed new plug wires for it from my MK2 GTI, still no luck. Decided hall effect sensor in the distributor was no good, nothing triggering the coil to fire. Replaced distributor with a known good one, hooked everything up, and.. nothing. At this point I'm kind of at a loss. Some mechanic has been playing around in there before, and I'm wondering if perhaps some wiring was put back incorrectly. It's been some time since I've played with Yugos and Fiats, so im not sure if I entirely remember which colour wire goes where. As it sits right now, this is the configuration.
Coil wiring, blue w/blk stripe and solid red wire on (+) side of coil. Solid green wire on (-) side of coil.
Coming from the ICM, beginning from left o right are 1, green, 2, brown. Both to hall effect plug on distributor, 3, red, 4 is a bare wire that runs in the same insulation as the hall effect connector wires, 5 is black, 6 is an aqua blue colour.
Does this sound right? And if that is wired properly, is it possible that that ignition switch could have shorted inside and is no longer powering the ignition? "Start" position had already failed, and P/O wired in a starter button. I don't think we tested for current on pin 4 for the ICM as it was nearly 105 degrees outside and under the hood of a Yugo wasn't really where I wanted to be after a couple hours. But I do believe we tested for continuity on all 6 wires and everything seemed to be intact. Only the bare wire didnt confirm continuity. As I said, kind of at a loss.. which is weird considering how humble and simple the car is to begin with. Any and all thoughts/suggestions are appreciated. I really miss driving Yugos and I'm pumped to get this one back on the road.
Thanks,
Joe G
