1996 F250 7.3

[steed383]

Hello I have a 96 F250 7.3 was running fine got in it one morning spun over like it wanted to crank had white smoke coming out of exhaust went to work when I got home tried again spun over no start changed fuel pump,cps,fresh fuel filter oil filter and oil batteries and oil. When I turn it over no oil pressure on gauge and tach barely moves checked HP RES had only about an inch of oil in it filled an inch from top and it turns over sluggish brought to dealership they said I need a new engine dont really beleive it beacause the motor was running just fine before this. Talked to a mechanic online he said the problem could be the starter is taking too much juice and he also said the engine oil pump could have went out and its not feeding the HP pump can someone please help me

I would lean towards the oil pump. I bought a non running 94.5 and after filling the hpop it would try to start (until it sucked all the oil out). Figured it was the lpop. Changed it out. It was an $80 part at Advance Auto, it is external too. Just have to remove the fan, balancer and there it is on the crank. Changed it out and it fired right up. When they go, they go. No warning at all...

Charge your batteries up, clean all your connections all the way to the starter. You may also need a starter, but it should build some pressure even if it isn't spinning to speed.

ok thank you I forgot to add that the dealership said I need a new engine because it has no compression thats why I dont beleive it. It would blow white in morning but none afterwards I just dont beleive it would lose it all at once.

Well checked batteries they were at 11.97 so I got tha wife to turn it over while I checked drew down to 9.5 to 9 at times someone said I need 10.5 for stuff to work. So I went to pull starter one bolt tight on bottom,one bolt missing on bottom,top bolt about to fall out and was full of crap when I pulled it out. Im gonna go ahead and put new starter hopefully this is the culprit will post back if it is.
