Brin, your problem may be in the ignition switch like mine was. No guarantees but I had the similar problem on a different tractor, a 1700. Also read the post below. Here is a link in case it moves. http://www.tractorbynet.com/forums/new-holland-owning-operating/288801-tc-40d-starter-problems.html I think a lot of starting problems are really ignition switch problems. I am not a mechanic, just an old try to do my own work guy.
TC33D wont start

I have a 2007 TC30 that did the same. After a 1/2 day of searching I found a small relay that is for the starter start circuit. I replaced it...all ok now

Check the ground cable where it bolts to the frame and make sure it is clean.

Well, Here I sit, read through this LONG post and have tried pretty much everything here (I THINK). My 2004 TC29DA has been down for a month. It stalled while I was bush hogging around a swamp. It took some maneuvering and some serious winching to get it to a spot where I could tow it back to the house. From there I began checking the battery, cables, fuses, and relays. My PTO light is on even though both my PTO are disengaged. I can physically turn both shafts when they are out,and can't turn them when the levers are put into "gear". Checked the two wires hooked up on the left underside and the switches, they look good. Connections were cleaned and didn't show any corrosion. Solenoid relay clicks when key is turned. Swapped relays too. I can hot wire the tractor to get it started, so I know my started works, and the battery is charging correctly. If I choose to put an on off switch, and a push button, I can use the tractor but this nulls any safety switch or interlock. I just did this to get the tractor into the garage.
I am open to suggestions. Does anyone have a scan of the schematic in the owners manual. My manual was lost in a flood three years ago (the tractor wasn't flooded).
Any help would be appreciated.

What is the voltage at the start relay? Even though the connections are clean, one of those safety switches may be breaking down when a load is applied. Don't rule out the ign. switch yet. Use a jumper wire at the switch to bypass it.

Where is that relay located?

I have a TC45DA. Similar no start condition unless I jumper the fuel shut off solenoid to the battery. I started down a few threads and discovered a set of wiring diagrams (schematics) for a TC45D. My 45DA is slightly different. Does anyone have a similar diagram to the post that jinman (rip) created back in 2009. Here is his post- http://www.tractorbynet.com/forums/...erating/137391-tc-40-glow-plug-problem-2.html
The issue is probably the Seat Switch or the Operator Safety Module... Do these fail that often? I found a seat switch on Messicks (87385234). But I'd like to confirm before I spend the $'s

First let me thank you for taking the time to help many New Holland owners out we all appreciate it. I have a question though on your diagram do you mean to go through the safety interlocks or wire directly to the new relay. I would sure appreciate any help. You can also call me at 214-616-5245. I have had trouble ever since I bought this tractor with starting it. I love the tractor hate the electrical problems. Again thank you so much.

It has been a while since I checked in on this website. The answer to the above question is yes, I did mean to go through the safety interlocks for the starting circuit. It would certainly be possible to eliminate them from the circuit, but I do think they make the tractor more safe. The modified circuit should allow the starting solenoid to work as intended even if the new relay receives less than full battery voltage.
This fix has worked perfectly for me for years now. I have zero electrical problems with the tractor since making this change. I have had no problems with the key switch, timers, or relays after the modification.
