Hi all,

I recently bought a 1999 Ford ranger 3.0 v6 5 speed. It runs pretty good most of the time. But it’s my first manual, and I’ll occasionally kill it, and sometimes when I do it’ll crank but not start. It’s throwing a code for o2 sensors (according to the guy I bought it from, I haven’t ran it myself). the next move seems obvious to do the sensors, but I’ve just never heard of o2 sensors causing an intermittent crank no start. Usually crank sensors or maf sensors come to mind there.

does anyone have any thoughts? I’d appreciate any input, this is my first truck and ford in general, don’t know much about em other than that the 3.0 is allegedly pretty reliable. Thanks much!

edit: its worth noting that the day I bought it it broke down (I’ve got pretty rotten luck with vehicles lol) and wouldn’t crank, no power at all. I ended up shotgunning an alternator and jump starting it since the battery was pretty new and that seemed to fix the issue. Til this morning when I tried to pull out of a steep driveway, killed it, and then it cranked but didn’t start. Funny enough, after turning the radio off and giving it a second it started, which makes me wonder if it’s still voltage related. Could’ve just been coincidence though.
