Start with the basics, do you get the wait to start light?

Was it running when you bought it?

Do you know if the CPS has been replaced?

Do you hear the fuel pump when you first turn the key on?

Do you get any smoke out of the tailpipe when cranking?

How good are your batteries? Do the turn the engine over fairly fast?

Also you are in the wrong section for your question, I notify a moderator to get it moved to the proper one.

When I bought it it would crank for couple of seconds and it would start white smoke would come out of exhaust.
Fixed leaks on this truck. I turned it on after I got done fixing leaks it idlesd for about 10 minutes and suddenly died.
Now it won’t start. There’s no engine light on. Yes I can hear fuel pump and ready to start light comes on but then goes away

Welcome to The DieselStop
Did it run when you bought it?
If the bulb check (instrument panel lights when you first turn the key on) doesn't work, then you aren't getting power to the computer.
Check the fuses first.

Sounds like something blew when you shut it down how far did you take it down fixing leaks.

How's the oil level in both the pan and HPOP?

Where are you at? Someone needs to get a scanner on it to monitor some parameters while you are cranking. Like Bugman said - start with some basics in the meantime.

Check your oil level - these trucks fire the injectors with oil pressure, so no oil - no start.
Check your fuel level - above a 1/4 tank? There is a known issue with pickups rotting off in the tank causing a no start below 1/4 tank.
Make sure your Wait to Start light comes on. (Do NOT use starting fluid unless the glow plugs have been disabled)
Open the fuel drain valve on the back of the fuel bowl. Watch under the front axle area while someone turns the key. Should have a healthy stream of diesel flowing out the drain tube.

Other than that, double check everything you did when you repaired the leaks. Make sure you got the harness back together and the bolt tightened at the connector. Make sure there is no chaffing on that wire that rests on the valve cover. IPR and ICP harnesses plugged in?

Hopefully someone close has a scanner.

If your oil gauge just sits on the bottom of the scale you might of lost the low pressure oil pump that supplies oil to the engine and the HPOP. Or your oil level in the oil pan is too low for the pickup to suck any up.

Pull the plug on the HPOP that is on the top and see how close to the top the oil is. If it is low refill it with the same oil that you put into the engine and then try to start the truck.

Good info, but the very first thing you should do is pull the dipstick and check the oil level. Refilling the HPOP reservoir would just be a very short term band-aid if there's not enough oil in the pan for the LPOP to pick it up.

When was the oil last changed. If unknown, change it now. Get the fuel tank to at least half full.

This smells like air to me. Sniff sniff.. yep, air.

Actually, Im not the most knowledgeable so take my advice with caution.

All I know is my truck has the rotted out crap in the tank and when I get air in the lines she gets real *****y. Like I didnt answer a question right when asked. It was a set up as usual... just didnt keep her topped off frequently enough.
