if you need to replace the ignitor or coil... there are tons of us with lots of spare parts in the garage..... being in OR there are tons of MK1 guys in the PNW.
the ignitor is self grounded through the bracket it bolts to -- which is bolted to the chasis. If it's not bolted to the chasis in it's original location and you have it out for testing, use a jumper cable from the negative to the bracket (or directly to the ignitor). All toyota ignitors are self grounded... meaning there isn't a wire that runs to them for grounding. The coil's "negative" is the pulse signal sent from the ignitor (black wire). The brown wire should be a constant 12V.
The next thing to check.... is there are 2 connectors on the distributor side that are green... pull them both off and look inside (or look at the back of them) to see if the wires have pulled through. Because they're in a horrible location, it's common for people, when disconnecting them, to pull by the wire and not the plastic connector... which makes it REALLY easy to pull the wires out.... go to reconnect and although the plastic pieces connect the wires never actually make contact. This is common in these cars.
