Test for bad ECU?

[s.u.p.r.a]

Hey all,

Can't seem to get my switch/button ignition system working with my new engine/harness/ecu.

Is there a straight-forward way to test if power is making it to the ECU?

If it is getting power and there are no diag codes when the switch is flipped then is the ECU bad?

Thanks for any info. :aigo:

turn the key to the on position, the CEL should light up. if it doesnt then you can suspect that the ecu isnt getting power or is bad.

what was your setup and what are you going to now?
