What happens if you plug the truck in prior to staring?

 

What do you mean by plugging it in? The motor plug or the battery (I've done both)? I just put a new glow plug relay on and it didn't change a thing. Still does the exact same thing EVERY time... Turn the key on, wait till the "wait to start" light goes out then try to start it. It will crank for a short time and act like the batteries are going down but not start. Then I shut the key off and immediately try the same sequence again, only the second time around, it starts like a new truck. New batteries and new glow plug relay, 60,000 miles garage kept. Are there any 7.3 gurus out there that can help?? Not really wanting to take it somewhere and spend a fortune for something I might be able to do myself with a little help.
Thanks!!

 

Where are you located?

 

Bloomington, Indiana

 

Thought maybe if your close by I could put my AE on their but that is a little far from Nevada.

 

What rpms are you seeing on the 1st crank? I know 6.0s have to see min 150.

 

if i don't plug the motor up on cold nights (40's to 50's) it will not start until it warms up ! Also i've try'd to install two different programs in it, 1st was hypertech, 2nd just today a brand new Edge EVO CTS and once again the truck wouldnt take the program. Any Help would be great !

 

Don't know much about the Edge, most here use Dp tuner.

As for your no start, it's probably your GPR (glow plug relay). You need to test it with an ohm meter. In a bind you can jump both large leads for 30 seconds and see if it will start.

 

Thanks Scott, I'll Check that relay for sure. I just thought it was the norm having to plug them up at 50 or below. I've been hotrod'n most my life but Diesel's are fairly new area, but i learning quick though trail and error !

 

I know the trail and error one!
I usually don't plug in my truck (as much as I want to) all last winter she fired up after cycling the glow plugs a couple of times she always fired up in 10 degrees no problem.

 

I finally got it going. Never would have dreamed it with the symptoms I was having but it was the starter. I posted on three threads and got some good help and advice. THANKS!!

 

good find on the starter, that would be a big one on no start.

 

Good job. Sometimes its the easiest thing that just goes right past our minds.

 

Where did you get the new starter and how $$?
