18 - SPOUT circuit open or spark angle word failure
So you checked the resistance from pin 36 eec to the spout connector and got nothing? No resistance or infinite resistance?? Just clarifying
It's obvious but you made sure your spout is plugged in, right? Have you checked the resistance of the spout itself??
When you jumpered from 36 to spout connector was the spout plugged in or not? If not then did you make sure you connected to the correct side?
I'd love to help but we need more info on what you did...

Code 18 - SPOUT out or wiring fault - look missing SPOUT jumper, short to ground or open circuit in SPOUT wiring going back to the computer. Possible bad TFI.
The SPOUT enables the distributor to advance the timing beyond the base setting. Without a working SPOUT, you are locked down to the timing you set with the timing light.
Checking the SPOUT wiring
Tools needed:
DVM or Ohmmeter
10 MM wrench
Phillips screwdriver.
6 ft 16 or 18 gauge jumper wire with alligator clips on each end.
Anytime you make resistance checks, the circuit under test must not be powered on. If it is powered up during the test, your readings will be wrong and you may damage the meter. Do not touch the probe tips when making resistance measurements. If you do, your readings may be inaccurate.
Remove the SPOUT connector from the ignition harness by the distributor. Remove the passenger side kick panel and loosen the 10 MM bolt that secures the computer wiring connector. Use your DVM to measure the resistance between ground and pin 38 (yellow/lt green wire): you should see and infinite open circuit. Keep the DVM connected to pin 38 (you may need a helper at this point). Insert the DVM lead you previously had connected to the body ground into the computer side of the SPOUT connector. You may need some extra wire to extend the test lead, so have some 16-18 gauge insulated wire handy. If you extend the test lead, remember that the quality of the connections may affect your readings. You should see less than 2.0 Ohms: more than that indicates a wiring problem
The following is a view from the computer side of the computer wiring connector.

u know 86 turbo i might of had a blonde moment, i think i measured resistance from the tfi plug in, i needed to measure it from the wire where the spout plugs in, i tried a jumper from 36 to the spout and still got the code though so im still lost on this, the tfi mod was loose, and missing a screw, so i got one and notched it with a dremel and screwed it in still havent got to go back and check it again
its an 87 gt 306/w speed pro pistons, 1.7rr, maf conv, gt40 heads, bbk shorties, march underdrives, accell coil, wires, tfi mod, msd cap, no cats,
thanks jr ive reread the info u posted for me im gonna try it again tomorrow if i can get my ford truck running
thanks brandon
