The injector circuit is inside of the PCM.

If you have trouble finding a PCM let me know and I'll see if I can get in touch with the guy that I bought a spare from a while back, I think I paid around 100.00 or 125.00 total, and he flashed the VIN to it and mailed it to me.
Been a while since I have been in contact with him, but I am sure I can get in touch with him if I try.

Thanks for the offer! I haven't looked for one yet. Still had a glimer of hope that it was ICM or something else.
Swapped relays this morning for the coolant fans to check if they would stop. No luck there, still running as soon as the ignition switch is turned to run position. I guess this shows there'* something funky going on with PCM.
Next step I'll drop the PCM down and get some numbers from it.
Thanks for the help

OK, went to the local "yard" and found a 1994 LeSabre with damage to the r/* rear. This told me the car was running before it arrived at the yard.
Pulled the PCM down and it is a reman unit,same numbers as mine.
Installed it and the car started up instantly, ran perfect. The coolant fans now operate correctly also. I plan on a road test later, but sure it will be ok. I even left the PROM in the replacemant PCM as it was the same numbers also.
Now I just have to decide if I want to buy another reman from the dealer for approx $230 or go back to the yard and get another just for a spare.
I drive the car from Atlanta to Chicago once a year to visit my daughter and it would be nice to carry a spate just in case.
Thanks again for the help and replies.

Great news, glad it runs good for you now.
I would have replaced the PROM to be on the safe side, but if it runs fine now I guess there is no real use.
If another spare is under half the price of the one from the dealer I'd just get the spare.

I'd suggest you verify the speedometer is accurate. If the donor had a bit different final drive ratio the speedometer would seem accurate but be off somewhat. I believe all LeSabres with 4T60 non-HD got a choice of 2.86:1 or 3.05:1 . Maybe check it against a GPS to be sure.
