So I replaced my crank position sensor yesterday and she started right up. Tested it about 10 times and all was well. Took it around the block and she sputtered and died. Wouldn't crank again and I had to tow it back. Sounds like no spark but I figured the cps would fix that. Any ideas before I go digging

Well that's the first thing I did, Everything is still tight and connected as far as I can tell
No check engine light except when it wont start, but that's normal. CEL is always on when the ignition is on and the engine is not running
I have not pulled codes, This one is a 94 so is it just OBD1? Can I rent a code reader from Auto zone or something? My reader is an OBD2 only reader so I have never messed with OBD1. Although im sure codes would help. I've read a post about the codes corresponding to a blinking check engine light after 3 key on/offs but I have never been able to get that to work. I haven't tried it on this jeep so I'll give it a try.

BOOM, Altough I saw your post after I found this, I still give you credit because it would have got me there. I was trying to see if I had spark at the plugs and distributor, I pulled this off(the wire going into the distributor, not from the distributor to the plugs) and decided to swap it with the one on my other jeep. She fired RIGHT up, and purrs like a kitten. It always seemed liked it was missing spark on a cylinder somewhere, and this has got to be it!
