But, if you can keep track of them. they will last at least 35 years. Of course the sets I bought were much cheaper - maybe not if you figured the value of the dollar back then.

I would just buy 2 ga. battery cable and make your own or order a set from Raceday Mechanic and be done with it.

Father in law brought over his code reader. He could hear the lift pump when I tried starting it, but could not hear any starter noise / click at all when I turned the key.

The only code came up as p0380 circuit a. I've been reading through the posts here about testing the plugs and relay. Could this have caused my original problem? Or should I focus on getting it turning over before I start getting sidetracked?

Once the snow dies down I will try digging under the hood and tracking down all the wires from the battery.

The key is acting up more and more as I keep trying it. The part the key goes into has to be about half way between all the way out and pushed in to the column or it will not turn.

Getting the code reader hooked up, I found some extra wiring under the dash behind the pedals. I will try to post a picture and see if any one knows what they are. I'm guessing that it is something for the wheelchair lift.

Thank you all for your help.

This is what I found behind my pedals. I think it's for the wheelchair lift but I thought I would post it in case it's something important. Thanks again for all the advice

You can check for voltage on the little wire to the starter with the key turned to start.

If you have no juice there, it could be your ignition switch.

You can do the push button start. Hook a wire to the little stud, run through a push button switch and fuse then back to the 12 volt source of your choice.

When you push the button the truck should turn over. If you cycle the key to run and aloow the glow plugs to cycle hitting the push button should start the truck.

Thank you all. Sunday I finally got a chance to take a look at the van. I started to get into the more complicated stuff, and then stopped and went with the easiest option first. I hooked up a second battery with jumper cables and the van started right up.

With the warmer weather we've had this Monday and Tuesday it is starting fine on one battery again. Once it had started, the error message for the glow plugs went away as well.

As soon as I can, I will get the second battery wired in so I don't have any problems down the road, as well as going over all my wires.

Thank you all. Since the van was running on one battery when I got it, I assumed that it had to be something more then the battery. Your advice saved me replacing parts I didn't need to, or worse yet, a trip to the shop.

I'm sure I'll be back with more questions as I work on this project. Now I know where to find the answers.

Thank you
Ben

Glad you got it started. I think it was posted earlier, but it is essential to:

1. have two matched batteries with at least 850 CCA capacity
2. good battery cables
3. clean and secure grounds

I had my electrical system checked not to long ago. According to the testing machine, my glow plugs draw 127 amps, not to mention the current draw required by the starter.

Have batteries load tested before you buy them. If they do not test like a brand new battery should, move along.

The last time I shopped, I tested 4 or 5 and bought 2
