Alright guys, Just bought this 1999 7.3 drove it a couple days now and got to walmart today. shut it off to go inside and came back out. turned on key waited for wait to start to go off. cranked the motor over but it didnt fire. i tried it again and nothing. oil is full, oil pressure is good while cranking. no rpm reading on gauge while cranking. no check engine light. batteries are literally brand new two weeks ago. Any ideas? cam sensor? im stranded at walmart until i get it fixed

 

Without seeing any data, and based on you saying the tach isn't moving while cranking, if I had to throw a part at it I'd start with a cam position sensor.

 

I second that, worse case you end up with a spare, which a lot of us carry anyway, for situations like this. Make sure you buy OEM only. There are known issues that can surface from the aftermarket ones.

 

Gave it a cam sensor after it stalling and having a bouncing idle when I got it restarted. It started up and ran good home. Hopefully it stays the same today! Thanks for the input guys

 

Did you put in an oem sensor??
