98 yukon wont start, which sensor???

I have a 1998 gmc yukon with 109000 miles on it. On saturday it ran good. On sunday morning I went out to start it and nothing, it would turn over but would not fire. Since then I have changed the coil, the module box that hooks on the side of the coil, The fuel pressure is 65 pounds and the plugs are wet so I know its getting fuel. also It has alot of spark. The only thing I can think of is its a cam or a crank sensor. What do you guys think, Thanks in advance. :banghead: :banghead: :banghead: :banghead: :banghead:

That don't ad up. If you have both fuel and spark it should atleast buck or fire. Try a little starting fluid down the throttle body and see if it'll fire.

I know it really does not make sense to me either, We tried putting fuel down the carb/throttle body opening and it popped threw the carb. It will almost start but just does not do it. thats why I was wondering if it was a crank position sensor. Thanks

Well, I thought for a moment that 65lbs of pressure sounds low???? Have you checked that it's correct?

yep I checked that and they say that is right.
