quick refresh on what i did: van quit while driving, no spark was found, replaced crank sensor, with new one, no go, replaced ecm module, with 4 different ones from the scrap yard, and ones that were known to be working, tried used pcm also, still nothing, tested everywire running from ecm to pcm and crank sensor, found bad connection at crank sensor, still no spark, when i scanned it came up with error 42, was cleared nothing showed up again after replacing the said parts above, im pulling my hair out trying to find out what the problem is, is it possible that anything else i havnt checked, we found all the grounds and cleaded then up as well, is it possible i got bad crank sensor twice from store? at this point all take any suggestions besides a match lol. we have access to any shop tool we need.
