Lots of white smoke and rich fuel smell

I have a 94' F-450 7.3 turbo, everytime I start it it smokes (white) bad and has a rich fuel smell. I push the pedel to the floor and it is sluggish for a second or two the I get the rpm's with the smoke and smell the same. Thanks in advance for any help.

do you have a powerstroke or an IDI, This good be a sign of bad glow plugs, bad glow plug relay. Does it have difficulty starting?

It is a powerstroke. If it is around 20 or 30 degrees outside I usually have to let the glow plugs cycle twice before starting. How do I check the relay? Thanks for your reply.

I check mine by:

When it's a cold start condition: I jump the large terminals on the gpr (watch for sparks) and hold for 30+ seconds. Then I start the truck. If there's no change, it's time to look at the glow plugs. (If there is no change, it doesn't mean your gpr is absolutely good, but it does let you know if something else is the matter.)

If you do replace the gpr, look into the Stancor 586.

I checked everything with my test light except the glow plugs. The relay stays on for 1 minute 12 volts. Have to get batterys for my ohm meter roads r too bad have 2 wait till tormmorow. Do you know what resistance I should be getting at the glow plug? And also can I test for ohms at the valve cover plug?

You can test at the harness. As you look at the harness I believe you will have two five-pin connectors: 1-2-3-4-5. 1 and 5 are the gp's. 3 is the ground.

I'm not sure I know the proper resistance value; I believe it's .2, though. (Considering your Under Valve Cover Harness is good.)

Replaced all 8 glow plugs, found 2 injector wires that were under the valve cover that wer cracked and had wires exposed to the oil so I replaced the under cover harneses. Started the truck up still had lots of white smoke. I drove it around the block( i live in the country so it was about a 10 minute ride) One thing I noticed is that between 1200 to 2000 rpm it makes this sound coming from the rear of the engine that sounds like the blower motor of my cab heater is on high. During this time it smokes white. when I got back to my place the smoke at an idle disappeared . But if I put it in neutral and get the rpm's between 1200 and 2000 it smokes white. Any Ideas?? The truck has not seen alot of use in the last year.

Well I talked to a mechanic today and he thinks since I have a exhaust leak before my turbo that there is not enough back pressure for the turbo to work properly and that is why I am hearing the noise between 1200 and 2000 rpm. I hate the thought of taking exhaust bolts off. Does this make sense to anyone??
