How are they blowing? I've seen a few lately with holes in the centre near the connector, just looks to be age related. If you are blowing good ECUs then you probably have a short in the wiring somewhere.

Let me be the devil's advocate here - accurate information aids diagnosis.

1 - How many ECUs has it blown/times have you repaired the ECU?
2 - What did you change - the cap or the ECU?
3 - How did the other person test it?
4 - If he put your ECU in to another vehicle and it worked, what's the probability that you have a fault elsewhere?

In short - your initial post suggests you have replaced/repaired the ECU several times, however, the follow up posts, suggest otherwise.

Most of those ECUs are shot now, if its not been rebuilt within the last 10 years then its probably on its way out anyway. You should check your wiring for shorts but with ECUs that old its best to start with a recon. unit.
