i have a 2000 7.3 and the other day i was driving and it started running terrible so i pulled over and cut it off. got out and checked the oil and the dipstick was bone dry. wouldn't start after that. towed it to my house drained the little bit of oil and replaced the oil filter and added new oil still wont start. checked HPOP and it was bone dry also. tryed filling it with oil and still no start. also i get no movement from oil gauge on dash and do get white smoke from tail pipe. please help

 

Well the rule of thumb for smoke is:

Black- poorly burning fuel
Blue/grey- oil
White- unburnt fuel or steam

if you HPOP will not stay full your LPOP may have dead or the pickup tube is bad.

 

If you are getting white smoke, injectors are trying to fire. You might try to unplug the icp and see if it will help it to crank.

 

ok i will do that. thanks but i should also mention that on my initial inspection the oil pan underneath was covered in oil and also oil was present under HPOP and in the valley. is it commoN for oil to leak at bottom HPOP

 

the hpop can leak for any one of it plugs. there is one on th bottom of the pump that can leak. here are some pdf of the pump
