4k loom with 4age starter issues

[henrike70]

Have been swapping 4age into my 83 sedan, entire loom was pulled out at some stage and now I’m having trouble putting it back in correctly and getting 4age to start.

I can hear my fuel pump going but no starter click or crank at all - definitely not a dead starter. 

the junction box on the drivers side has plugs that seem to be able to go in multiple spots so to start with I was hoping someone had photos of how the plugs are supposed to be in there so I can get that sorted before moving engine side where I think I will also have issues 🥲 image attached of junction box for reference :)

I'm not that keen to pull mine out to photograph it, but as I remember it the plugs in there are carefully shaped to only go in one place. Some plugs are not used at all and just hang there.

That circuit is purely KE70 chassis, so it should be as it was with the 4K. One wire from the key to the solenoid.

Was it an auto KE70 that you put a 4AGE into? That's the most likely issue, the 'neutral position' cutout on the tunnel must be bridged.

All good on the photo, I found an old photo on here. It was an auto ke70 that I put a 4age into, I bridged the wires on the tunnel and now able to get crank but now no spark.

Power is going to the ignitor from the ignition wiring but nothing on the spark plug ends.

Any ideas?

Could be a few things- what wiring diagrams have you got? Bigport or smallport?? There are two ignition setups on the 4AGEs, VAST and something else I've forgotten. Everyone wires their car individually, but I used a Diahatsu COR relay box-

 

So I used the stock B/O wire that goes to the passenger side for ignition, but ran a relay off it and that powered the coil. There's another wire in the chassis loom there to take the tacho reading back to the dash.

and I used these pinouts on my Bigport-

 

IGF and IGt are the igniter wires.  Here's a diagram I used a lot, but none of this can be relied on unless you really know what engine you have and what the diagrams actually reference to.

On top of that these engines are really old now and everyone has had a play with changing the wiring, so the colours can't be relied on either!  I'm just as bad, I'd hate to buy my car and try to trace wiring!

See what you can trace and let us know.
