KE10 won't fire

This should be dead simple and i'm sure it will be.
Just picked this little baby up and the trip from Adelaide to Canberra was fine. Started 1st go this morning too but as i was warming it up i pulled on the heater fan and the engine just died and wouldn't fire after that (turn over but no spark). Exactly what you'd expect if a fuse went but checking the fuses in the main fuse box didn't come up with anything? Is the engine fuse elsewhere?
A pretty simple system so figure it must be a fuseable link but where?

Drop a V8 in it. 
Seriously though, the fusible link should be somewhere near the battery terminal. A bit of probing with a multimeter should reveal where the problem is.

Maybe some of the wires are getting a bit old too? This sort of thing would happen on the celica xx sometimes when it was trying to start. Power would just die in the arse until I jiggled some cables. Replaced the wire with overkill 8 gauge wire and it works like a dream now 
Of course in this case, you just aren't getting spark. Is the coil getting power?

I haven't had a chance to look over it in any detail yet as had to do the bolt to work. The fact it turns over no probs and just won't fire (after suddenly cutting out) suggests a fuse but there's no 'engine' fuse in the fuse box? Just thought someone might know where they hide the bugger if there is one?
Multi meter out this arvo i guess.
Damn as the car ran faultless from adelaide.
PS a 1U looks possible Norbie...quite a bit of work but possible

Bah! Every man and his dog has a 1UZ these days. You know my thoughts on the powerplant of choice.

Maybe but it's all about what they are stuffed in i reckon
Still, your fave is on the options list

KE10's dont use fusible links. If it had one and it was blown, chances are the car wouldnt turn over at all. Try unbolting the fuse box from under the dash, wobling the connections around with a bit of WD40 and with any luck, it might work. Do it to all the connections whilst your at it. Sounds silly, but you'd be suprised. Worked on my car plenty of times! As you said, theres nothing to them, so theres probably nothing thats actually broken thats causing the problem. Unless your coil or dizzy's faulty?

Sorry should have been clearer....they are all fuseable links but i know what you mean. I wasn't referring to the fuseable link off the main positive just another fuse somewhere in the system not in the cabin fuse box. there's usually a 'main' or 'engine' fuse for the ignition circuit but not on here apparently?
The engine cut out the instant the heater fan switch was pulled on, just as if a fuse had blown. Power was good to everything i checked before i had to run. if there are no other fuses to check then it is multimeter time

Most older Toyota's have separate engine and heater fuses so what you have happening is very strange. It almost sounds like you have an open circuit when the heater fan is turned on.
Did you switch that off and try to start it again after that ?

Yes strange indeed, although i have ago given up fathoming the gremlins that can appear in old cars 
You wouldn't credit it but i'm not 100% sure i did as i was in a mad hurry to get to work and beat Canberra's horrendous 10 minute rush hour .
Like you say an open circuit would do that but why only to the ignition circuit? i'm betting the solution will be dead simple but no doubt totally obscure....probably held my tongue at the wrong angle

Before you poke and prod with a multi-meter just switch things on and off, one at a time and see what else may cause the problem, like the rear screen demister (high load) for example.
Then pull each fuse one at a time and see if that can isolate the circuit the problem is on.
Its likely to be a partially broken wire hidden in the loom somewhere.
And speaking of the tongue at the wrong angle, you would have seen this before now ???:

1, there are no relays in a KE10.... at all...
2, the only fuses are the ones on the dash above (or touching ) your right knee..
3, replace ALL fuses, as the old fuses may look ok but can be corroded internally, and has the a pita for many many people..
so yeah, swap all fuses first.
the heater power is on the wiper fuse.. but ya never know
here's the wiring diagram
http://www.materials.unsw.edu.au/~sford/KE10wiring .jpg
the headlight power to the steering column is NOT FUSED (only after the indicator stalk switch is it fused) so i would suggest fusing that one fast
do the usual like check for power at coil, then check for power at the IGN and ACC.. after that, it's time to look for burnt wires... also check the wire from alternator to starter motor and if possible replace with a wire direct from alternator to battery.... and then....

Lucky i cut my teeth on this old school gear, took me 20 minutes but found the little bastard Ended up being the points....i haven't even seen, let alone pulled, a set of points in at least 15 years The ramp for the dissy cam had collapsed so the points weren't opening.....i guess the drive back to Canberra from Adelaide was a tad too much
Thanks for the responses guys.

so it was just a freak that it happened just as you pulled the heater fan on? Bizarre.
