are you saying cummins have no glow plugs? my dads dodge ram has a red light that we assume is the glow plug light as it shuts off in 2 seconds. My moms ford powersmoke has a glowplug light and let me tell you it takes fooooorrreeevvveerr to turn off in a cold start.

About 58 degrees this morning and no go. I gave her a couple long cranks and she didn't have any signs of life. I didn't want to kill the battery so I hooked the strip fuse back up. Lots of unburned fuel in the system! Fired right up with an RPM spike and lots of smoke.


So I guess the 603 will simply not start cold like a 617 will. Interesting bet it has to do with the head design.

Aha! Perhaps we now have proof/evidence that the 603's will not start without GP's. Now I don't feel so inadequate because mine wouldn't start without them.

Why wouldn't the engine be able to start? If it has fuel and the valves are closing and the compression is good then shouldn't it start after some cranking?

Even with a short glow these motors dont start up always or idle well. The aluminum sucks up the heat I'd venture to guess.

Yeah its strange. My tired 617 will start without glow plugs. Strange must be part of the 603's design.

They dont' have glowplugs. The Cummins uses a heating grid/element.

I wonder why Dodge can start with no plugs but the Powerjokes (They have the same compression ratio as the Cummins) can't start cold without plugs.

i wonder why powersmokes have GP's and the cummins have a heating element. Its amazing!

I had a similiar thought after last year's winter when my wife's 300DT wouldn't start -even WITH working GPs.

Last winter, a friend of mine started the diesel engine in his boat with the help of a burning piece of paper in front of the air intake, and it started. I will try a hair blower this winter, maybe that works too. Any thoughts?

hahaha I've actually used a hairdryer to get a 617 to start before...

Had an 82 300D I took home in the winter and was about to drive to work the next morning and it did not want to start. I knew it had some dead plugs so I had left the blockl heater plugged in overnight. Well, so then I learned the block heater element was burned out.

Strapped up a hairdryer directly over the opening in the filter housing and let it run a few minutes then fired it up.

On another occasion I've used a torpedo heater infront of the radiator to heat one up enough to start (but only when the hairdryer won't work )

My SD started right up this morning at 32 deg WITHOUT glowplugs. Took about 4-5 seconds of cranking.

Why? 2 totally different engine designs. Thats why.

Powerstroke Diesels, the 7.3L T444E and 6.0L VT365E are designed by International.

the Cummins Design has been the toaster oven element design for a while. Which is great for roasting marshmellows when camping!

How are you disabling the plugs? The only viable test is to either pull the strip fuse or disconnect the 6-pin connector from the relay...

On a side note, I find it's much easier on both myself and the engine to just keep the glow plugs operational.

Yeah I don't lnow why anyone would not check to make sure they are working, and fix them if they were not. There is no reason not to use them.
