My 2001 f 250 7.3 liter diesel engine started smoking badly and making lots of noise I pulled overand kill the engine and let it sit for a few minutes. I try to start in again it bellowed out a lot of white smoke. It took off at a high rpm I'd turn the key off it bid not die right awoay I have not tried restarting again. Does anyone know what is wrong with it or how much it might cost to have it repaired

I have a'96 7.3. Recently when I start it and put it in gear, the engine pulls down and acts like it is in drive and reverse at the same time. If I don't do anything the engine dies. If I get on it pretty hard it will take off and drive ok until I stop, at which point the engine wants to die. Don't know if it is related as I had a bad connector on one of my batteries, but I can't keep the batteries charged now. Put the charger on for several hours, disconnect, crank engine no problem. Next day, batteries dead. Thanks for any suggestions.

Off the top of my head I would say that the Fuel injection regulator is not functioning,/ stuck closed. It is located in the center valley of the engine. To Test You need to borrow or buy a "Diesel Mechanical" fuel pressure pressure gauge set, or sometimes have them at Harbor freight that can handle minimum 5K. to test for excess pressure. BE VERY CAREFUL!!!!!

I replaced my engine in my 1999 with a 2000 engine and it would stall out then start up when it rained and snowed. I put electric greese on the camshaft plug and the problems went away. Moisture is getting into the electrical conection shorting out the relay.

I had the same problem with mine. I replaced the water seperator valve then the leak stoped. the leaking fuel runs across the top of the engine then drains out the back running down between the engine and bell housing making it look as if the transmision is leaking.

The oil presure gage does not move up after I start it. If I turn the engine off then restart it the guage works, any ideas????

Hi sounds to me like it could be turbo bearings worn for the following reasons.
1 engine noise and smoke,lack of oil because it's going into the engine via the turbo.
2 white smoke could be engine oil burning
3 took of at high rpm,engine is running on hot engine oil which will burn like diesel and will normally keep going until it use's all your engine oil (if the engine does not explode before that)
4engine does not stop right away, this is because it is burning your engine oil not the diesel which you stop when you turn of your key.
Please check your engine oil level and then your turbo for wear

I would still say you have an injector stuck in the open position

Do I have a water separator on my 1995 7.3?
I changed my fuel filter and still get a hesitation once in a while.
Thank you Jim
