1G Bad ECU or Something Else?

[bossku69]

About a year ago I was driving my Talon home and it began to stutter, ran really rough and barely got it into my driveway. Next day it wouldn't run for more than a minute or two and hasn't since. I had it in my garage at the end of the fall and into the winter and just now getting the time to get back to it, but the car won't start and kept toughing off MAF codes, so I replaced the MAF sensor and no luck!

I didn't notice at first, but now do clicking sounds coming from behind the dash, so researching it leads me to believe it's the ECU, however is there anyway to "easily" tell? I took it to a garage and they told me it was the alternator - , right...

ECU is out and I can see some corrosion, but is this worth sending in to a place like ECMtuning to repair, or buy a new one?

A picture of the whole board would help.

Only the vendors can tell uou. Doesn't look bad for what little you posted.

I posted like 6 pictures, but see only two got uploaded. Sorry about that, I'll link the rest.

It's an EPROM ECU so it worth having the guys at ECMTuning try and save it.

The corrosion is pretty well advanced. It still has the original capacitors which is why it's now hurting.

Thanks. I emailed them yesterday afternoon and haven't heard back, but hopefully will soon.

I'm not sure what else the issue could be as to why the car won't run, but everything I'm reading is pointing to an ECU problem.

I can tell from the pictures that you have a problem with the analog to digital converter. There is corrosion damage to the external capacitor on the reference voltage next to the CPU. That's going to cause all sorts of problems reading the voltages from the TPS, BARO, O2, and temp sensors.
