I bought my son a nice '97 7.3L F250 about two weeks ago. He hasn't had any problems out of it in the few days he's driven it until last night. He cranked it up to leave and was pulling out of the drive when it died for no apparent reason. We pushed it back in the yard and it won't do anything but spin over. It doesn't even attempt to fire. The batteries are new. I put my Snap-On scanner on it this morning and it won't read. It won't even power up unless I hold down the reserve power button and when it does, it goes through the KOEO process then says "test aborted: engine not responding". I thought the problem might be with the scanner, so I put it on my '95 and it worked perfectly. I even did a buzz test on my 95 while I had it on there and it worked without holding down the reserve power button.
Any suggestions at all? I assume that if the scanner won't even read power, then it must be something eletrical or computerized? The lights, radio, etc. all work perfectly. It just won't start.
I bought the truck from a local used car lot
, but it was as-is, no warranty.
