jump but nothing
 
She was starting just fine in the mornings, about 20 degrees with a block heater. Last night we got the first big snow, bad roads and all but didn't get as cold as it had. Went to start this morning, nothing, won't even try to start. So I tried jumping it, checked the starter for any slush that might have got caught there, and now have it charging. The dash lights/lights go on and look fine.

I have been reading that a cold snap can ruin an old battery, does it sound like a battery problem? I'm checking the wires and grounds now. Just wanted some ideas.

Need more info. Is the engine turning over with the starter? Is the glow plug light working?

Sounds like you're on the right track. Charge battery fully before contiuing. You also want to make sure your battery cable conections aren't corroded, as this will cause a no-start condition. If you can get a load test on the battery, that would be a good idea.

There's also the off chance that you have a problem with the start switch or associated wiring. You can try bypassing this with the always-handy screwdriver across the starter terminals to see if you get a different result. Then again, it could be that the starter went bad, but they usually give some warning before dying completely.

Glow plug light works just fine. Engine won't crank at all, turn key-nothing. Yeah the starter gave no warning. I'm going to go bar the terminals now.

Barred the terminals, lots of sparks, but nothing. Even though thte starter gave no sign of being shot, this makes me think that's the problem.

I'm assuming autozone isn't going to have one of this in stock...

Try jumping terminals 1 and 3 in the junction box on top of the right inner fender in front of the battery.

Go with a new battery first, AutoZoo's should have that Duralast pretty good.
Doubtful they'll have a starter.

Mattbob 12-05-2007 08:37 PM

I'm not seeing the junction box you are speaking of. I'm searching for pictures now. Would this accomplish the same thing as barring the terminals on the solenoid?

With the car hooked up to another vehicle aren't I running off of that car's battery? I would think this would eliminate the battery as a problem.... that's just what I think, not from anything I know though.

Three inches long, one inch wide. Plastic lid. It depends on what terminals you were jumping on the starter.

Mattbob 12-05-2007 08:55 PM

I was jumping the two terminals directly above each other. I found a black box along the wall on the passenger side, I thought it was supposed to be in front of the battery. I'm going back out to see if I can find the terminals in there.

The item you want is a black box, red circle, you'll have to open the lid, there should be three screws, first and third, you can use a pair of pliers, or anything of substantial metal.

The car was in D. Not in P.

I'm an idiot.

kerry 12-05-2007 09:20 PM

Not the first one to do this.

cheap cables?
 
Here is something to keep in mind. When you jump start a diesel , you'll need a good heavy set of jumper cables. Not the kind you'll find in a cheap emergency kit. My cables are made from 1/0 welding cable , these are the only cables that will jump start my mbz , backhoe or tractor. The cheap cables will get hot or even melt from the amount of power that is needed to start a diesel.:D
