ecm/code 26 qdm? no spark!

hi i have a 1990 riv. 3.8 and have a no start problem i read the forum and replaced the crank sensor btw 190000+ miles and the coil it looked burned by the yellow wire connection still no spark i did not have a alignment tool as recomended by the repair book no one has one so i gaped it at 0.30 like the instruction's said too, anyway i had the module tested it was bad,replaced it and the car started
i drove it around for 2 hrs and then let it run for another 3 i pulled the following code's 28,27,26,24, 42. i then shut it off and let it set for 1 hour then tried to restart and nothing no spark again i checked all fuses and grounds i cleaned all connections (grounds and power block) prior to replacing the module
does anyone know were the ecm is located? i pulled a box out from behind the glove box( there is another box just under it above the kick panel but i cannot get it out,)
# on it from delphi delco svc#01228786 went to delphi's web site no match is this the bcm? the "chip" that i need to keep and put in the new ecm (i can get one from a junkyard but i really want it from checker auto parts for $89.99 )is not the same there are two of them and won't come out
btw the sticker on the box says remanufactured so it has been changed before?
would a bad ecm cause the no start problem? any suggestion's would be helpful! thx,

I had similar issues on our old '86. We had replaced the module and it ended up needing to be replaced again. Is this the module that has a flat metal heatsink that required the thermal grease? That could be part of the problem... ??

thx for reply no it did not require the grease it is the flat metal box that mounts just beside/under the alt.
