Hi thanks for the help, just bought 1987 f250 6.9 idi. Manuel glow plug and starter button.
Bought truck off dude, hit glow plug button and fired up quick, it was cold too. Drove it 2 hours home, parked it fired it up a couple times later that evening no problem what so ever. The next day no start. Maybe ran close to out of fuel? Put 10 gallons in nothing, hit shrader value on fuel filter while cranking and nice steady stream . At least 1 glow plug had 6 volts didn't check them all . And white smoke comes out of exhaust when cranking with foot on pedal, and it smells like diesel. Is that unburned fuel? If so, running close to low didn't clogged anything up if its smoking unburnt fuel right?
Just got the diesel I've been wanting and got half a day out of her before problems.
Any advice helps, I need it . Thanks

Couple of things , could have air in system making it hard to start or you have some bad glow plugs which will act like that. You need to check all of them to see if good.

How cold? Has it got a block heater? If so plug it in for a few hours and while you're at it charge the batteries up. Every diesel has a cold weather personality. Some of them just plain get cranky when it gets cold out. Cold weather tests everything - little bit sloppy on the compression, batteries not quite up to it, injectors not spraying just right, glowplugs not 100% involved - basically if everything isn't just perfect you'll get what you're getting - white smoke.
