bad ecu? pics

Are these smoke marks on my ecu? It was smoking from under the dash, but is this enough to make it go bad? The caps arent leaking I dont think, i just have these marks.

Did the car still run with the ecu in the above pictures, Installed? Does the ECU smell really bad?

Please read my long post about this, yes the car still SOMETIEMS start but it was very hard to even keep it going. The car wouldnt run for more than 3 minutes at a time, like one try out of a hundred would acutally casue it to decently run.


The ecu doesnt smell bad, but something was smoking from under the dash.

As for the arching, Check your coil pack to make sure your sparkplug wires are all on. If they are, Check ALL the wires, And electrical tape ALL of the wires that are not already covered or showing bare wire. Do you have access to another ecu? If so, See if it helps fix your problem.

could be your ecu or your mpi relay.

I just dont want to borrow my friends ECU and end up frying that one.

Do the exact opposite then, Try your ecu in his car! See if his car runs with your ecu.

Now that I think of it, I replaced my alternator at the same time I did timing belt and water pump beucase it was going crazy and overcharing the battery.

As soon as I turned on the car with the bad alternator the volts jumped to 17 and it just kept rising, so I immediately turned the car off.

This probably fried my ecu.
