Have I Fried My Ecu?

[cam_ae92]

Before i start, my car is an Aus spec AE92 with an AFM 4AGZE.

 

I installed an A/F ratio kit from jaycar a few days ago, it was only going to be there temporarily. Anyway, to cut a long story short, I left the Oxygen sensor wire off and it was on the interior, this morning i started my car and the oxygen sensor wire happened to touch the steering column and sparked (i didn't realise the thing was live!). The car then stalled & blew the EFI-Heater fuse under the bonnet, i replaced the fuse with another 15A fuse (reccomended type) and it just keeps blowing them, the car turns over but won't start.

 

Any suggestions? every other fuse seems to be good, there is a couple of chunky things in the underbonnet fuse box that look like relays and are listed as EFI-Heater as well, could i have blown one of them?

 

How can i test if it is the ECU or not? anyone got an AFM 4AGZE ECU for sale?

just on the fuse side... if a fuse keeps blowing then there is too much current flowing through the wire, the fuse is blowing just before the rest of the circuit does. too much current is usually caused by a short circuit especially if the fuse blows very fast. if it blows normally then there is still too much current from something in the circuit not providing the correct resistance, ie a faulty component or incorrect wiring.
