He mentioned a no-spark condition so diesel engine is out. Many refer to crank position sensor as ckp on gassers. Ford calls it VRS variable reluctance sensor on EDIS6 systems. On a 4.0 it's diametrically opposed from #8 in the diagram.
93 ranger 2wd 4.0 it is the crank sensor,the thing about it is when it does fireup you can just touch the sensor very lightley and it will shut down..
Well, you are right on top of it, and pretty much have it narrowed down. It's going to be one of the problems subford mentioned. You need to get a good light, and being very watchful, take the plug off the sensor and inspect everything you can to see if you can spot the problem. You never know, the problem might be the connections on the sensor itself.
Or, if you could buy that part of the harness, and a new sensor, that would probably fix it without worrying about what the real problem was.
just want to let you know that it was the ckp sensor,and want to thankall of you for your help with this,just wish i would have found this fourm sooner,so anyhow thanks again....
