was driving my 84 down to my moms (4 hrs away) was almost there and car quit, had fuel pressure no spark. hooked my scan tool up every time i checked a mode it said "not used" put a code reader in it said code 41. its got a new cam sensor cap. could my alarm system be doing this? pulled it the rest of the way, it sat for awhile cranked up. is my module going out? the comp is a 86 out of a fwd that i converted. thanks, mike
