I was driving down the interstate at 70, and suddenly there is a slight clunk then I loose all power. I pulled over and tried to start it, and it just turns over nothing else. Its leaking no fluids that I can see and it ran like a top untill now any ideas what it is.

cps,try and unplug it and back again,sometimes this will help.I would check for spark and fuel,it is one of the two,I doubt it jumped time,as it sounds like it turns over fine.
When you say clunk,did it sound like something broke?

It kinda sounded like my serp. belt popped but it still on. Other than that its hard to explain it just died. Sorry for stupid question but what does cps stand for?

crankshaft position sensor

your cps is just watching the tone ring on the flexplate,most of the time when they go out it is due to being dirty,or they develop a high resistance that causes a poor signal back to the ecu,it is located where it sees alot of heat and dirt,also the ckp or camshaft position sensors go out,but cps is more common.

man that sucks... hope i can get this thing fixed tomorrow its about to get lifted!

If it is the cps,you can replace easy enough,when you are just driving and it just dies,and does not miss,loose power,studder,it is the cps.

ok that pretty much sounds like what that is. where is it located at?

Abovetimberline

top left side of the bellhousing,it is pita to change,but is onlu held on b y two bolts,I would try and unplug it and back,and spray some cleaner on the pick-up,it is not a fis but it may just fire up and you will know what the problem is.

00XJ

if it is the cps i might just replace it but do you know any way i can test it with like a volt meter or something so i can know for shur?

yea,check it across terminals c and b,it should read open,yours is a 3 wire and mine is a 2 wire,check c and b.
