Reprogram ECM?
 

My cousin has a 92 Saturn SL (POS). She drove it home one night, parked it outside the house, next morning it wouldnt start. I went over there to see if was maybe an easy fix and discovered it wasnt getting any spark from the coil packs. Apparantly, that Saturn has 2 big coil packs instead of a distributor.

They called out a local mechanic with some diagnostic tools. He did some trouble shooting, no spark for him too. He used his scanner tool to check the ECM for codes (no CEL) and it rang a 48-F (if he remembers correctly). He told me that they have to take it to Saturn to have the ECM reprogrammed.

How does an ECM break without being physically hit and just lose its memory?

lol, to get reprogrammed.. ---- that. both the manual and auto ECM's are interchangeable, so go find a first gen SL/SC/SW, pull out the ECM and throw it in.

I think it's trying to delete itself. I don't blame it. :l

Re: Reprogram ECM?
 

oh, forgot to add, you can use any of these

sl
sl1
sc
sc1
sw
sw1

any of those ECM's, since they are all SOHC 1.9. The sw/c/l 2 is the DOHC 1.9 and isnt the same ECM.
