E6K - smoked coil packs and no fuel pump - repair or toss?

[S15IN240]

I have been running an E6K on an S15 powered 240SX for several years with no problem. I was away for about a month on remote assignment and now the car has no signal tothe fuel pump and I noticed the coil packs smoking(!) while sitting with the key in the ON position. Sounds like my E6K has gone south. Can these be refurbised, or do I just have to replace it with an E6X? I ran a 2 amp trickle charger on the battery and figure that it must have fried the unit somehow as there were no changes and it ran fine when parked. Thanks in advance.

Anybody got an idea?

You need to ascertain first do you have a problem with the ECU. If it is damaged, it can be repaired by Haltech still I beleive, but you can pick up an E6X model very cheaply which is a huge upgrade for you , just on the easier tuning option and probably give you better ability to run Sequential injection as opposed to the multipoint option only no the E6K model.

Just got the ECU back from Haltech and they said it checks out. Anybody have any idea what would cause this to stop working in the car just out of the blue? I have checked the harness with an ohmeter and cannot find any shorts. Can the trigger or one of the sensors cause this?

One possibility is the dwell time used, if its set too high you can damage the coils in the long run. If the ECU checks out, my suggestions are these, sell it, for what ever you can get from it, since it checks out from Haltech it shouldnt be too bad, and get a new Platinum Sport unit, the end results is much better performance from the engine.

Worst case scenario, you can get an E6X and review this thread to modify your harness to make it work with the X.
