1995 Ford F350 won't start
 

My 95 F350 with the 7.3 turbo diesel won't crank. It has brand new batteries and a new glow plug relay. The truck will turn over all day, but it acts like it's not getting fire. What is wrong with my motor?

Check oil level, voltage needs to be over 12 volts, is tach moving? Smoke from tail pipe?

When you first turn the key to the run position, do you get a wait to start light? Does the starter spin the engine over fast? These engines need to crank over pretty fast. As starters age, they tend to slow down, and you don't realize how slow they get until a new starter is installed.

I have a wait to start light, and the starter spins the motor over fast, it just won't fire, it has plenty of oil in it and it does smoke on start up every now and then. I was told it could be the IPR Valve or Cam Sensor, tach is moving and is over 12 volts

Do you have a CEL?

Check oil in HPO Rez. Need to near top.
