Rebuilt the capacitors on the same board that came out the ECU. After I did the water pump timing belt sparkplugs it drove good. Then just died. Wouldn't even start. So I rebuilt the capacitors on the ECU put it back together and started it started right up ran for like 10 minutes took it around the block soon as I pull back in the driveway it died

Have you recently messed with your MAF sensor in any way? It's also possible that it has gone bad but this would need to be tested to be confirmed-- that usually does not happen.
Do you have a copy of the factory TSRM within which there is the official troubleshooting matrix? If not, I can send it to you (can't seem to attach it to this post).

just wondering, my 94 SC400 starts up only when I give it some throttle and if I stop revving it it dies out immediately. I was wondering if I should adjust the idle RPM or just clean the MAF? I read that the CRC MAF cleaner shouldn’t be used on some models of Lexus’s but it didn’t specify which ones... any help?

I am going to see if I can get a friend to rev the engine while I go to check for vacuum leaks, since the engine dies if it’s not constantly being revved... speaking of codes, where on earth is the OBD port on these cars? I checked under the driver side dash, near the left floor panel, and in the fuse box but I can’t seem to find one?
