7.3L IDI Diesel Cold Start 29F No block heater

Just what the title says. Truck had 1 bad glow plug. This should show you what a difference just 1 bad GP makes when cold starting. 29F*F or -2*C Truck sat for 3 days.

1989 F-250 4x4 ZF5 speed

YAY FOR DEISEL COLD STARTS!! My 88 Chevy (not deisel-sorry) kinda starts the same way as this thing in the cold. Haven't had to plug it in since I've had it, and it's kinda funny watching neighbours try to start their new cars with them being plugged in.

@blackhawk8427 nope I'm in norther Illinois so thats a bit far away. Thanks for looking though and the info you gave me.

Teh 6.9 L and 7.3 L were good engines. I repaired many of those, found broken pistons, holes in the top, and one of the things found was the oil cooler bypassing the engine coolant. You have to be some kind of skilledi in order to replace the oil cooler ends, some pressure has to be applied. These engines can go for may miles without any problem.

Hi, if you have oil in the antifreeze, it could be a cylinder head gasket. There is an oil passage from the block to the cylinder heads to lubricate the rocker arms and part of this oil pressure could be going to the antifreeze. Remember th oil has more pressure than the cooling system. The oil cooler is just to cool down the engine oil, it has passages of coolant and oil. These ends should be inspected in order to find any cracks or any other damage.

@blackhawk8427 Hey, we have a F350 7.3 Diesel International, 5spd, but the ignition will only turn over and put the battery lights and all that on the dash on but wont crank the engine, to crank the engine over to start it I have to touch the solenoid with a screw driver...Any idea what I can check or do to fix it? or do you think the ignition switch is just bad? Also when I turn the key over there is no dinging sound like in yours...
Thanks! :-)

@blackhawk8427 Yeah I was looking at the f350's cause most of em had a solid axle the only problem is the 1 ton is really hard to find with 4x4. The only way I'd want to buy a truck is with a manual unless its an insanely good deal.

[brambo]

@blackhawk8427 Cool man, I'd appreciate that...This is our first Diesel pickup truck and biggest we ever had, it's just a pain to always open the hood to start it...Can the solenoid go bad if we keep starting it that way?

Yup just 1 burned out glow plug can make a big differents in cold starting.

[qfdforme]

Just like mine. New glow plugs did not help.

@mightyjoelaith i had 35s on my stock 89 ext diesel. you can fit 37 without rub easy if you wanted too.

[GearHead]

@blackhawk8427 Did you have to do much to it? I saw the video from when you fixed the front end. other than that was it really reliable or not? I really want an old idi like that love the sound and the looks of em.

[CrimsonInHumanBlood]

trying to start mine this morning my block cord is bad. so its been a pain with my 7.3 91 ford. having to charg my batteries. anything i can to do to cold start it better

[ChevyDieselBoy]

What the hell was that noise at 0:44?!?!?! That sounded like something from an alien movie. Hahaha

[c_mauro]

for high Idle on auto 7-3's don't you put the pedal halfway, or fullway to the floor when cranking it then let off or something? idk..

[Thinker]

You spend almost a hundred bucks on glow plugs?

You shouldv'e got a cummins, they have no glow plugs, instead they use a grid heater along side of the engine block. It's alot easier to start when it's cold outside.

[ZR]

Mine smokes like that until it gets up to ot. Thought it maybe glow plugs but thinking shitty injector ? What you think? After she's warm its good

[GearHead]

That is a really nice truck. How much did you pay for that awesome piece of machinery?

[tanksor]

you should see the vid i got of a diesel cold starting it had the starting and dieing problem and i hadnt figured it out

[MrSonic]

i want to buy 1 but the only problem is the rust is somewhat bad, when you open the door and look where the black strip is, thats all rusted out, and the front fuel tank is leaking, but other then that its nice, and it only has 118k miles. and if anyone knows how to fix that rusted rocker panel plz tell me.

[jack]

how is the high idle supposed to work on an idi?
