Dumb noob question

[laserjock]

When starting an IDI, foot on the fuel pedal or off. My gut says on but this is my first diesel.

Feel free to poke fun at me now.

outside temps under 32*F, hold at WOT while cranking then let all the way off once it fires.

outside temps above 32*F, hold at ~half throttle.

^^^^ What he said

My sun viser say what he said. If I remember right it says 7.3 diesel starting instructions

 

['94IDITurbo7.3]

i thought the visor said it but couldn't remember if it was that or the manual in the glove box.

That, plus you have to give it a bit of throttle on any cold start to engage the fast idle solenoid.

Well when its timed bang on or pretty close and the glow plugs are working as they are supposed to, you should not even need that much pedal. I have started my 84 in 18 below (centigrade) with a little more throttle then the fast idle solenoid provides. Then again; I have had rigs that needed WOT to start well, must have had higher mileage, worse plugs and timed incorrectly

 

[X-NRCan_IDI]

would there be any negative effects to starting it without depressing the pedal?

 

[91idi]

Out of habit I always start diesels in cooler weather wot. Then let off as needed. I don't exceed 1500 and let it idle on it's own as soon as all cylinders are firing. My 4020 john Deere is fun to start, you can count cylinders coming to life. It takes three then slowly the other 3 start to lite.

Laser jock, theres no such thing as stupid/dumb question....just stupid answers.

I'm also curios does it do any damage if you start it cold without throttle?

That's what the Owner's Manual calls for.

FWIW, I always start mine without pressing the throttle, at least not while cranking. I stab the pedal once or twice to engage the cold start/high idle, then crank without touching the throttle (after the Wait to Start light goes out, of course). Fires within a second every time ever since I put in new GPs and fresh batteries.

Truthfully, I have never used the pedal when starting. If it's cold, I will pump the pedal once after turning the key on to set the high idle, then once the WTS light kicks off push button and vroom.

Altho, with only three working glowplugs, she is REALLY cranky for the first five seconds when I start her lately. (*** Vegas? Why you soooooo cold?)

 

[turbo elk]

For the past 5 years I've turned the key... foot off throttle ...wts light goes out....crank till it starts....wait 2 or 3 seconds...tap throttle to engage high idle...




And wondering if when I'm in a hurry I will start moving slowly not letting the RPM's get above 1500 after about 1or 2 minutes ....is that OK?

 

[Can30Diesel]

Interesting. I've always stomped the pedal once then turned the key. Tapped the pedal once its fired up to kick in the high idle and let it do its thing. I've been curious about what the right process was for a while now. But apparently not curious enough to ask.

Yeah, new batteries make all the difference in the world. The guy at the auto parts store couldn't understand why I wanted 2 1000 CCA batteries for my truck when the computer said it called for something less,
