Hey All,
I have an 84 FJ with no spark – I did a compression test [120 across the board on a motor with 500k ! ] and fiddled with idle and vacuum last Friday night and upon reassembly, the bloody thing wouldn’t start.
Did all sorts of test, wiggled and reset connections, tried different wires, straight jumping to the coil, etc. Signs are pointing to a blown igniter module.
I have a few spare modules from old 2f systems [2 wire, smooth black box] vs. my ridged silver, 3 wire module. I am not certain what the extra wire is for - the truck is equipped with AC, and I have heard rumors that there is a connection between the AC and the Igniter Module, so I am presuming this is said connection. The AC is currently disconnected.
So my question is this:
Are there any issues with using the older, black-box 2 wire ignition module, presuming I leave the AC circuit disconnected?
Thanks in Advance,
Crash
