Well, the FJ62 is up and running again. It was a failed igniter, as the first shop diagnosed. Fortunately, they were wrong on the ECM diagnosis, it is fine. They seem like good guys (anybody can make a mistake, IMO what's most important is how you handle your mistakes). I'd use that shop again, if necessary.
Re: My experience with Cruiserparts.net - They did not send the exact part numbers I ordered, but they certainly had the best prices, and have been very courteous, so far.
On the C/I igniter ass'y, I'm still not sure why the numbers don't match, but Cruiserparts.net assured me that it would work in my truck, and a friend who works at Specter gave me the same opinion. The coil that came with the C/I ass'y was a rotted piece of junk, but that wasn't the part I needed, as my old coil is okay. The truck fired up and ran fine as soon as I replaced the igniter. It seems to be doing just great, and my son is ecstatic now that he has his (MY) car back

.
On the ECM, Cruiserparts.net sent me the "Federal" ECM. The part numbers are close, but they don't match. I'm sure the truck would run with this ECM, but I don't believe it would pass CA smog certification. I'm going to send the ECM back and ask for a refund on that part, mainly because it's the wrong part for my car, and also because I don't need it, anyway. I would have been willing to keep it as a spare it was the correct part.
Anyway, thanks to all who offered suggestions on mechanics in the area. I'm sure I'll use those resources in the future. A special thanks, again, to Mo for offerring to come over and help.
Take care,
Joe
