Has anyone had a chip failure. And if so is there anything that I might have inadvertly done to cause same. I had the heads off for improvement which worked out well. Then coil and leads went and were replaced only for chip to fail immediately.

was theis bad look or might I have done something stupid?

An aftermarket chip or a chip inside the ECU?

No CEL's showed up prior to failure.
There is no spark (sensors have been changed) and ECU can't be read.
I don't know what part of ECU is failing, but it is at least the part that controls spark.

No ecu/chip mods were done.

It sounds like someone may have disconnected the PCM with the battery connected or key in the ignition.

Maybe they forgot to hook the PCM ground lead back up.
