I don't know if anyone here has found out yet, but the white plumes of smoke & loss of power are due to the faulty fuel cells installed by ford. This problem is known as delaminizing. This occurs when the coating inside of the fuel tank flakes off and contaminates the fuel delivery system. If the vehicle stalls, and it will, you can wait 15 minutes or so and restart. The only fix is to replace the fuel delivery system. Victim,2000 E-350 / 7.3

Hey you're not alone. EGR stands for Exhaust Gas Recirculation, which is a fancy way of saying that the engine sucks exhaust gases in before the turbo and pumps them into the intake, thus inducting the exhaust gases back into the cylinders to be burned again by the engine. This reduces emissions to comply with Federal laws that were put into effect back in 1998 that demanded manufactures make their vehicles burn cleaner. It's a good idea in theory, but wreaks havoc on the engine. Just like the Government!
Because diesels by their nature burn so dirty and create so much carbon, pumping 1,200 degree exhaust into the engine would cause melt downs. The cooler is supposed to cool down this gas, but ends up doing nothing but getting plugged with carbon and if left unchecked will force carbon into the fuel injectors, and give you another $4,000 bill. This problem can be avoided by bypassing the cooler all together.
So by plugging the cooler, you can not only eliminate the cooler from being used, thereby eliminating and chance of it getting plugged, and create a much more efficient, cooler running, more powerful engine. Now your intake will be taking in clean, fresh, cool air free of any exhaust gases.
Unless you live in California, do it ASAP and save yourself a world of headaches down the road. Depending on where you live, I highly recommend taking your truck to Bill Hewitt down in Georgia. The cost of him going through your truck and bullet proofing your engine is a heck of a lot cheaper than pumping EGR coolers, turbos, and injectors into your truck.

Hope that helps!

have you checked your fuel injection control module (ficm). your injector has two sets of coils. low and high side. during start up the ficm needs to send 48 volts to the high side of the fuel injector. if the module is going bad it will not send the needed voltage to actuate the coil thus very hard start with extreme rough idle along with surging ,sputtering, and sounding like its about to die out. i just went through this several weeks ago and after replacing it made a world of difference.if indeed your ficm is going out you will have trouble codes that will not always throw a check engine light.reading your description of start up sounds i would lean toward this being your problem.

7.3 Diesel has oil leaking on top somewhere, anybody have any idea what to look for, does not appear to be coming from the air charger or turbo. Seems to be towards the front of the motor.

Probably loose or worn connection from battery to starter

My 99 has 180k miles on it. Starts fine and runs fine after it warms up. If I start it and don't allow it to warm up for about 10 minutes , it will run rough and eventually die,then after cranking for a while it will crank and run rough until it warms up.
Does not show a code CONFUSED !!!!! HELP ????

Does anyone have any idea why a 97 7.3 diesel would idle rough and have no power until it warmed up? It has a code PO236 for Turbo Boost Sensor A Circuit Performance. Thanks

Hello everyone, I have just started reading through this. I have a few things to add and a problem maybe you call can help with.
I have a 96 F-250 Extend Cab. Recently it began to give me problems blowing the #31 Fuel Line heater fuse over and over. In the process of getting it back to the yard it also took out my head gaskets. After some length of time, It was in actuality the fuel heater coil inside the fuel filter that become desoldered enough to arc and short the area. I replaced the head gaskets and had to replace the main harness with one from a late year truck.
My truck was manufactured prior to Feb of 96. The truck I borrowed the parts from was manufactured after Feb of 96. According to ford the build date is very specific in terms of the fuel filter harness but not the master harness.
I borrowed the Fuel Filter housing from the newer 96 and bought a new harness from the master to the filter housing itself (My companies cost at ford $45.00) Upon completing that nightmare, I had to refill the oil reservior to get it to start. It has been a week since then. Currently my truck (350k miles on body and frame 140k on trany and new crate engine from FORD) will not start without a shot of starting Fluid. On cold mornings when the truck is plugged in it still requires cycling the glow plugs three or four times followed by a shot of fluid. This usually requires two or three repeats to get it started and running.
From everything I have read here I can check the Cam position sensor, When I had it diagnosed it threw a oil code and one about ehaust leak. The exhaust leak has been fixed(tightened the brackets surrounding the turbo and replaced the flat o-ring between the flanges.
Any ideas on what is making this truck such a pain in the A$$ to start? Thanks for your time.

I am replying to your message about oil leak. I have a 02 f250 7,3 diesel with same problem. It is not from air charger or turbo it is the high pressure oil pump which is located right under the fuel filter housing if it same problem. What mine does is leaks out on the center head the it drains down back of motor and comes out the inspection pan for transmission which at first thought it was rear main seal. Then i changed rear seal and did not fix it so i talked to local mechanic at ford garage and he explained to me where to start looking and sure enough it was high pressure oil pump. Now what goes bad is o-rings in the lines. There is 3 of them line 2 on top 1 on bottom. You can change o-rings in top 2 but the bottom 1 you have to change the whole pump and all. My truck has 318000 and is the only problem i ever had with it.

I have 1995 ford f-350. I'm wondering if it is the oil cooler is leaking inside. no water in the oil.
