6.2 turning over, but not starting.

[Lonesome715]

Thanks. I do plan to use the truck so any upgrade or fix I am interested in doing.

If you do try to energize the glow plugs out of the engine, realize that they can be easily burnt out. One truck I bought had a new set of shiny glow plugs installed by the PO. I tested the circuit, knowing that the glowplugs had just been installed. After trying everything else, I came back to the GPs and tested each seperately. They had burned out 7 of the 8 new plugs by testing them before installation!
To test each plug individually while still in the engine, just hook a simple test light to your positive battery cable. Remove the GP wire from the GP and then touch the terminal of the GP. If the light comes on, it is good. If it fails, it is bad. The working GP is actually just a dead short electrically speaking. When they burn out, they are an open circuit.

fyi, look at the glow plug troubleshooting thread, you cant always tell a bad plug with the test light, measuring the resistance is the only good way to check.

 

[Lonesome715]

I plan to go ahead and purchase new plugs. What type/brand should I get? How much do they usually run?

Use Wellman 070's. These are the stock plugs that the military uses. If you go to Autozone or some such place, they will give you AC60's (I think?). These will not fit the stock CUCV glow plug connector, the tips are too wide.

When I needed them, I ordered them through INDUSA ($60 + shipping)

Or, you could maybe use one of the other distributors listed on WAP's (Wellman's) page at:

Thanks. I will see if I can get some ordered before I go home. What esle should I replace at the time I deal with the glow plugs?

I'd like to remind everyone, this is not a CUCV. There is no big resistor on the firewall and the glow plugs may be different. I'd bet that the AC60 plugs will fit fine. It would be best to pull a plug and cross the number.

On a side note, I converted my 1031 to 12v and use the AC60 plugs. I had to file down the terminals to fit, but they work great...

Here are some photograhs of what I am working with.

I still have no idea which forum it belongs in.

Being since it has a CUCV cab, wouldn't it still have the same military version of the 6.2? I am only guessing here. Can you give me some details on converting your to 12V and how you got the ne glow plugs to work?

How about some under the hood pics?

I'm not really sure where to post it. It's not really a CUCV cab, just a Chevy cab of the same time frame. It's been a long time since I messed with one of these, but I thought they were already 12 volt systems. I remember that we kept glow plugs in stock for both the CUCV and the Eagle bobtails and they were different plugs.

We had a lot of problems with the frames bending/cracking on these trucks. They don't really have any suspension on them. They would always be leaning to one side or the other when they came into the shop. The engineers came up with some adjustable links to make them ride straight. We ended up readjusting them every time the trucks came into the shop. The links didn't solve the problem of bending/cracking frames, but made the truck ride level for a while.

I believe Wellman has 12v plugs for those. Their website would show them.

 

[Lonesome715]

My wife keeps forgetting to get the photographs. Plus she is short and the truck is tall. I'll get her to take some now.

Here are some "suspesion" photographs. Aren't those little air bags cute?

 

[AJMBLAZER]

Are they air bags or just rubber pucks?

Fairly sure the one at my last airport job just had solid rubber pucks.

 

[Lonesome715]

My wife told me it looked like and air line. However, now that I look at it closer I do nto think it is. I do not think those are brake line so what could they be?

 

[Lonesome715]

Oh yeah, I should have some photographs of the engine soon.

 

[Lonesome715]

Here are the engine photographs. The engine bay looks pretty clean.

 

[Recovry4x4]

Did anyone else notice that this truck started life as a 2wd? I can see the pockets for the front coil springs in the frame shots.

 

[AJMBLAZER]

They all did. The government bought 2wd Dually C30's with no bed and sent them to the conversion company. Conversion company did all the rest.

The glove box codes on these trucks are very interesting when you decode them.

 

[Lonesome715]

Does that look like a military 6.2 version?

The decal on the air cleaner will tell you if it's a "J" code engine. It isn't a 24 volt electrical system. The accessories are set up differently than the CUCV engines.
