Sorry, I described it wrong. I know my wiring harness has some bad insulation deep down in the middle of it, I saw the cracked insulation when I last installed it but didn't take care of it because of other constraints at the time. The car has run fine for several years now, including a run to 2016 Monterey. I'm thinking the insulation finally failed when I crossed the freeway bridge and shorted something out in the ECU, I had something similar in an old Saab 900 I had. I was just going to have the ECU checked as a troubleshooting method rather than tear into the harness. I have a complete, spare rebuilt ECU from FI Corp (I may actually have two) but don't want to install it and fry that one too. Ignition wiring (123 dizzy) is all tight as well as the fuel pump wiring. I forgot to check for pump noise before I took out the ECU. I'll stick it back in and check that too.
But to my point, who besides FI Corp rebuilds D-Jet parts these days?
