Thanks for the insight !
Then as far as I can tell by the wire diagram it narrow's it down to yellow input voltage, black ground, brown crank voltage. the rest of the wires goint into the processor are A plug B plug or sensors. ???

Ok I've tried everything. It lights right up when in bypass mode but not when the micro processor is connected.

Earlier in the thread someone said toi check peak volts out of the crank sensor do you know what that spec is ?

no set output.
you should see about 1.5 to 3 volts.
same as the TPS should see about .5V to about 4v.
use an analog meter to check TPS output.
if not set you DVM to manual scale.
most DVM's will try to change scales at about 3 v.

OK the crank sensor is 1.6 on both wires and the TPS is .47 on the white and 5.6 on the red ...?

I'm really at a loss now ?
