Alright so I picked up a 1985 Supra the other day. Aside from some cosmetics, the only problem, it appears, is that the poor thing won’t start.
Before getting mad at me and linking to other threads or the TSRM, know I’ve already been there. I’m curious to see what other people say.
I am getting no spark to the plugs at all. Replaced coil, coil is fine. Plugs and wires look fine. Anything I can physically see for the distributor cap and rotor look fine. Also spins. Tried to test everything I could with a voltage meter. Also, when I took the whole distributor out, it did spark (because I’m not smart enough to turn the key off), telling me that is getting power. At least I’d think.
That pretty much just leads me to the igniter. Before settling on the ECU at least.
Before I took the thing out to get a better look at it, I tested the two prongs with the meter. Nothing. I want to say that those go out of the igniter, not in, but maybe I’m wrong. Anyways, upon taking it out, “84 cant make the word out Supra” was written on the bottom, telling me it may have been a junkyard part.
So, I want to say the problem is the igniter. Unfortunately, the closest ‘85 igniter is 492 miles away, unless a 7m igniter will work for it.
Lastly, code is flashing 14 and 41; code 14–no IGF, code 41–throttle position sensor. The three-hole connector by the wires for the diagnostics (someone took the connector off) is also burnt and melted. In case that makes a difference. One hole connector by those also seems to have been damaged, but looks more like engine heat than anything.
The color of the wires, if it matters, does not match up from igniter to the car, though. There is also a black wire with a rubber stop over it, which, aside from the double wire plug, is the only igniter wire that matches with a car wire. I was thinking of either running a wire from it to a ground, or hook up that wire to the car-black and stop the other wire instead.
I also checked as many grounds as I could find.
Basically, all in all, I would like to see what other, much more experienced people think. I bought her as a project and am just trying to get her started before cleaning and all. I want to save this thing.
