6.9 wont start without ether
my local scrapyard has a 6.9 that I know ran while still in the pickup, but it didn't want to start without using ether? any ideas on what would cause this?

6.9 wont start without ether
Glow plugs system isnt fuctioning properly... if it was the ether would be making it spit and sputter and eve "back fire out" the intake... i know i got mine on a toggle and left it on accidently DO NOT DO THIS IT AINT GOOD lol... but sounds like it had a problem with the glow plug system or it just wasn't hooked up. Now if they disconnected it on purpose to get it started it could be sucking air or have a fuel leak in one of the lines (but that coulda been back where the fuel line for the tank meets the selector switch. A clogging fuel filter.. could be a number of things but if the glow plugs were hooked up... that probley where the problem lays

that makes sense, cause the guy that had the engine rewired the glow plugs to a button under the dash, and some people (but thankfully not all) should not be electritions, my three wheeler is an example of this that guy had the lights wired to the coil! but oh well, it happens, thanks for the info

muscletruck,
I just gotta, gotta say to not use ether to start your diesel. Every source I've ever read says that is a BIG No-No. I was advised to use WD-40 for a primer, if necessary.
Also, while you're getting the glow plug system right, you might want to plug in the block heater. I guess the 6.9 has a block heater? Anyway, it will help with the starting if you've got it. R.A.

Will Wd-40 still work? Last time i tried to use it it wouldn't burn... they changed the compostion of it from what heard... but it you use ether make sure the plugs are off or disconnected... and for the engine size you dont wannt use more than 3 cc ( i spray a 3 second burst down the far end of the air tube to dilute it and i never had any probs.... use a either assist start in my tractors and a Ford LN8000 louisville never had any probs you just dont wanna wash the cylinder out or either lock it(6.9's with the mits starter are notorious for strippin ring gear with ether lock)

bigford,
Thankfully, I've never had to use a primer. I didn't know WD-40's contents had changed. Still, if Dumb (Haynes) and Dumber (Chiltons) also advocate never using ether, I'm on the wagon. Sounds like stripping a ring gear, or warping a piston, or snapping a pin, or bending a connecting rod, or damaging the cylinder wall are all real good reasons to not use ether. R.A.

dieselzen,
see the reason "dumb and dumber" advise against it for one is because of the glow plug system. because it can ignite the ether in the precombustion chamber, unless it is disconnected on not turn on it the case of a swtich operated glow plug system. It will do that damage if you use to much! 3cc is the recommeded amout for 300-500ci engines check a ether assist kit. But hey i guess chiltons and haynes needs to call John Deere, Ford, Navistar International, Peterbuilt and Kenworth along with some other manufactures and tell then not to put ether assist on from the factory. Vapor lock is vapor lock dosen't matter it is ether, WD-40 or Right guard deoderant bro. Anytime you induce too much vapor it will lock up.

Yeah, I see your point about the glow plugs igniting the ether all by themselves. Sounds as if you've certainly had a lot of experience with an ether technique. I guess if you're extremely careful.......
You're the first guy I've talked with who's used ether reliably. I hope I can always keep my starting system in good enough shape I don't have to experiment. Can't afford the consequences.

If you want to blow your engine to heaven use ether, if not, get the glow plug system fixed.
Ether will ignite, because of high compression in diesel engines, before the pistons get all the way up the cylinder and the explosion will try to force it down, imagine the pressure on the rods!!! It's like trying to swallow and vomitting at the same time, just my 2 cents worth.

Where do you people live Florida? winter it dropped down to -15 with a wind chill of -25 a working block heater and FULLY OPERATIONAL GLOW PLUG SYSTEM WILL NOT START IT... with fuel additive.... too cold PERIOD. My Glow plug system works perfectly and last time i checked (a couple weeks ago) I have less the 2 OHM resistance through each plug which is within specs from Ford, and the system gets turned on the correct amout of time 10-12 seconds according to HAYNES and continue to be kept on till after the engine is started. All my test lights light up perfectly when attached to the leads and I have between 360psi and 400 psi per cylinder. I never said ether was a 24 hr/365 days a year starter, I know what ether CAN do IF TOO MUCH IS USED. WD-40 has changed too they no longer use propane as a propellant. It's pretty much straight CO2.

Ambient temp is ambient temp to a machine.
It doesn't usually get THAT cold here in central PA. But I do have a block heater (that I hope works...) and I plan to keep her plugged in during the winter months.
Stupid question time: How do ya know if a block heater is working?
