Yeah, no luck. Still stuck in the driveway. The solenoid is clicking when I hook up the wire.

Any ideas?

Thanx.

Well, it can be glow plugs not working, fuel shutoff solenoid not working, air in the fuel system, lift pump not working, fuel filters plugged, IP needing a rebuild, bad battery connections, weak batteries, weak starter --- or a combination of all that.

To find out what it is, you need to check these things. Where do you want to start?

not necessarily. it was... 14*c yesterday, i had the block heater plugged in and only half the gp's and she started up a few seconds after i turned the key. no Dr. WD required.

Most indirect-injected diesels, regardless of make, will not start at 70 degrees F without glow-plugs. Doesn't matter if it's a GM 6.2, Isuzu 1.8 or 2.2, Deere 1010/2010, IH B275/B414, Allis Chalmers ED40, etc. They usually need to be over 100 degrees F if glow plugs aren't working.

oh i guess its harder to warm up the pre chamber without plugs eh? i enver knew 1010's and 2010's were IDI's they used ether though right?

1010s and 2010s were never supposed to be ether-started. That's only for Deere direct-injected engines.

1010s and 2010s used glow plugs along with a hand-activated fuel primer that squired raw diesel fuel into the intake manifold. They were the first Deere engines to use the Standyne/Roosamaster rotary injection pump- not much different that what the 6.2 uses.

My glow plugs were all bad and I could start up after using the block heater over night.

That's the first time I've heard of a glow diesel starting with no glow plugs. Even our '05 7.3 powerstrokes use them a little even if the motor is 100 degrees!

I dont need my glow plugs when warm. I dont need them first start of the day either if its warm out. I usually run them but they arent required. I dont even know that all my glow plugs even work. 243k miles on them and never been replaced. Kind of afraid to try at this point.... lol.

but thats a 6.5 so i wonder if it makes a little more heat in the engine while cranking compared to a 6.2

Afair the 6.5 has a bit lower compression and would make less heat. But they might use different starters, and when you run 5W40 in a 6.5, they turn over pretty fast :)

Starting shouldn't be a problem. I don't "need" glow plugs when the coolant temperature is down to 130 after sitting, but it's easier to start when using them. When it's below 180, I use the plugs for a few seconds to make it easier on the starter. But my starter is somewhat weak and might become a problem next winter.

Maybe the starter is weak. I just rebuilt mine today in my 6.2 and it turns amazingly fast! It is 45 degrees and I have 15w40 and only needs about 10 secs of glow plug action now. It may start on a hot day with no glow plugs now.
