1995 7.3 dually 4x4 starting issues

/Users/davidflanery/Desktop/IMG_0935.JPG


Hello everyone my second post, so I am pretty new. I picked up a 1995 f350 4x4, has the 7.3 with manual transmission. Truck has 139,000 miles on it. I didn't plan on buying a dually but couldn't pass the deal up. I am pretty new with diesel engines, only experience i have is with my tractor and never had issues with it.

Here is my issue which i knew about before buying. I haven't had to start the vehicle very many times since owning it (3rd vehicle) but it has happened to me twice where i have to cycle it 3-4 times before it rolls over. I have only owned it a week and started fine every time except yesterday evening. Then I moved it this morning and it started fine, then was going to take the kids for a drive tonight (they like the "big white truck") and had to cycle it 4 times. It will crank but won't turn over. When attempting to start it blows white smoke, once it starts it runs fine, you can turn it off and it starts right back up. It does blow white smoke for a couple minutes before it warms up regardless if it starts on the first try or it takes 3-4 attempts.

I am assuming this could be the glow plugs but wondering if it would be injectors also? Previous owner (which was the second owner) changed injectors and glow plugs around the years 2002-2003 but he could't quite remember.

If it is just the glow plugs would it be worth going ahead and changing the injectors during that time?

My ultimate plan for the truck is to due a restoration on the truck (not sure to what extent) and some mild mods to the engine. Nothing crazy....I have around 1-2 years before I can start the project (promised the wife a couple things first then she gave me the ok to do what I want). That's why I was wonder if I should change the injectors if there isn't a problem or wait 1-2 years and get the injectors I would really want.

Any advice or help is appreciated.

Sharp truck; I'm sure you'll like it. Are those 4x4 hub locks (pic is kinda small)? Must be some kind of conversion if so. "Crank" and "turn over" are the same thing. If it's smoking while cranking, and smoking after startup, glow plugs are a very good possiblity. Try plugging in the block heater for a few hours before next startup, see if that helps. Also try leaving the key in RUN an extra 20-30 seconds before turning the key to START.

How long does the wait to start light stay on? Just because the light went off doesn't mean the glow plugs turned off also, watch the volt gauge. I leave my key on for about a minute before starting, the volt gauge should go somewhere on the middle when the glow plugs turn off.

Have no idea why the pic is so small. Would post a bigger pic if I knew how. Yes those are 4x4 locking hubs. It's a centurion. Not sure the back story on it but pretty sure it's stock 4x4.

Thanks for advice. Light stays no more than 10 seconds. This morning it started right up. Not much smoke either.

my bet is a failing glow plug relay. the contacts in the relay burn over time, and will not send power to the glow plugs.
do yourself a favor and put a stancor relay in the truck. you will not regret it, it will be the best $55 you will lever spend on the truck.
