Had starting issues with the 1992 Aerostar. The whole past story of it is here, but to make a long story short. We found the problem to be the PCM (ford calls it an ECM for Engine Control Module). Got one at (think it was O'Reilly) and had it installed and then the van worked fine for about 5 weeks. The starter died two weeks ago and we had it replaced, then last week it would not start. My shop is swamped with the holiday and a man on vacation so did not get a chance to try their spare PCM. They should be doing that today. They did find that the injectors were not getting a signal on cold start. We could start it with starting fluid and it would keep running and even restart without the starting fluid once running. But yesterday I could not get it to keep running at all, it would fire over and run until the starting fluid ran out. Dead as a doornail.
So, the question is, if he finds the new PCM went bad, should we
1. simply replace it under warranty
2. return it and buy one elsewhere of a different brand
3. figure that there could be something else wrong that will keep messing up every PCM we install
If 3, is there a way to figure that out besides blowing several PCMs in a row?
If I had not put about $1000 into this piece of junk I'd junk it now, but really at this point would like to get it back on the road and reliably.
