Are there any error codes?
Have you checked the pins on the back of the ECM?
Bent, dirty?
If you swapped the chip recently, are there any bent pins on it?

Harness chaffing?

You can send me the ECM to test.

Feel free to bring the whole Scout by josh so that we can double check our installation and make sure a wire hasn't rubbed thru. We can also check for codes at the same time. Please call me ahead of time to make an appointment when you would like to bring in the Scout.

You don't need a laptop for codes.
Just put a wire or paper clip in pins a and b of the diagnostic connector and then turn the key on.
The light will blink.
Count the blinks and look up in the manuals provided with the kit.

Right now without the jumper, the light should come on when you turn the key on and then go off as soon as you start the engine.

It would be much more efficient if you called.

And I can vouch for that. Kit was brand new in the box. Not sure if you remember bill but I had you burn us a new chip to work with the 345 and I think swap us out on the TBI adapter.
