No Spark on 2 & 3

Looks like the EDIS module has failed.

Plenty of sparks on 1 & 4, and swapping the trigger wires on the Coil Pack, causes 2 & 3 to work, and 1 & 4 fail, so that rules it out.

Off to raid the local scrap yard and see if there are any more EDIS modules lying there.

Any other possible causes ?

Can always stick it the module on ebay if it turns out to be something else.

Maybe a bad connection in your harness? That's the only thing I can think of other than the EDIS module.

Hello Ken

The problem was presented once installed the rev-limit or is the second time you install a MJLJ?

Was running, fine with rev limiter, then suddenly went onto two sparks.

Now giving no sparks at all.

so I guess it is edis failing.

Waiting for new EDIS to arrive

despues nos cuentas como te va con el modulo EDIS, espero que la falla no sea producto de la instalacion del rev-limit

Off chance, you may want to check the wiring harness to make sure you have continuity all the way from the coil pack to the appropriate coil output pin on the EDIS module. Perhaps the pin was pushed back in the EDIS plug? It's worth checking if you haven't already.

Getting 12v at coil pins, and looms checks ok.

think it is the EDIS, as it's now failed completely. Not MJ/Rev limiter related as same problem with it missing so in limp home mode.

When the new one arrives i'll know for sure.

Just to clear this thread off.

New edis4 unit and car runs fine again.

Not sure why old one failed, but maybe just a time thing.

Thanks for the update. First reported EDIS failure, here at least? Pretty robust devices, those EDIS modules.
