First off the glow plugs are not the problem. Diesel's run purely off of compression. The basic principle behind them is compress the gas and and it will "spontaneously" ignite as long an the cylinder is hot. All glow plugs do is provide the initial heat that is needed. Once it is started they shut off. If you turn your engine off for a little while and then crank it back up, the glow plugs won't come back on as long as the engine is still warm. So now onto the actual problem. You have a FSD (Fuel Supply Driver) also known as a PMD (Pump Mounted Driver) that is failing. It tells the fuel injection pump when and where to deliver fuel. When they start going bad you will notice hestitation, to random stalls (usually when hot) to no-start situations. There is a forum I found which goes into much greater detail about it and how to fix it and help prevent it from happening again. CHeck it out. 6 5 NEWBIES START HERE

SOURCE: Heavy smoke on start up
sounds more like a worn turbocharger with bad seals. Sadly this will be expensive. Remanufactured turbos are available.
SOURCE: The glow plug system does not operate when you turn the key on
Go to your local auto parts store and look for a book, Haynes Diesel Engine Repair Manual, Part number 10330. It has your wiring diagram and a lot more. I got mine at Canadian Tire.
As long as there is not damaged areas, and all connections are the same. Should work.

The diagram is simple each glow plug is connected in a series circuit like this -0-0-0-0-0-0-0 that's a in-line 6 for a V-8 it would look like this
[-0-0-0-0
[-0-0-0-0
and the plugs would be hooked up on the back then if you follow the wire to the glow plug relay you will find that the relay has four wires one to battery one to the glow plugs one to the ignition switch and one to ground in the box. If you want you can purchase a manual for 5.99 on-line. and it covers the three fuse-able links for this system and the new Glow plugs available for this truck here is the web page. http://www.wiring-diagram.com/?gclid=CMuAvJ3Ql58CFQZfagod0jpAxQ

This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.
