No start

[strokinallday05]

Hey guys posted this a couple days ago and didnt get many hits. Im gonna throw it up here and see If I get a little more info. It has only done this one day so far should I still take it in??

Hey guys so my rig gave me the first problem since I have owned it (almost a yr) Its an 05 6.0( 84,000 miles) and today I came out of the store and all it did was turnover and keep cranking but no start! I tried a couple more times and then checked my CS. It read code P0336 Crank sensor so I looked in my chilton manual for it and found but its to dark to get to it. Finally after I let it sit for 15 or 20 mins, it fired right up so I drove it to my dealership to see if I can get the sensor looked at. I got there and it wouldnt start there either!! Same code came up. I checked the FICM its at 49.5 or 50 so its good, checked the ICP and goes to 30 psi my buddy duncan(mechanic) advised me the ICP should be at 500psi at crank and around 600 idle. Truck runs great once it starts lol

Now for the older and wiser advice from you guys. Should I buy the sensor and replace it myself or let them run more tests and change it?? I dont have a butt load of cash to throw at it either cause of trip I need to take. Thanks for any advice.....Chris



Update: I started the truck up on Sunday to take it to the shop and she started and ran great. My Icp Psi went full range almost 4000psi at WOT and 500-600 idle. I went to the shop but it pulled no codes on my Edge??? Anyways, Duncan wasnt in today so they advised me to wait until he gets in on Monday to look at it. It has been running great all day and has started everytime even when fully warmed up. Kinda lost as what to do next?? I have to drive cross country in a few weeks and dont wanna get stranded somewhere lol.

I highly doubt that the crank sensor (CKP) is bad. Save your cash on that one.

Does it seem to start better when it's cold? If so you have an hp oil leak somewhere.
