max 24 wont start

[MadMax24]

Hello everyone , new member here

Got a 2015 max24 with 25 hrs on it , wont start , blew black smoke at first , fuel smelled like thinner so i changed the filter and drained the tank , filled with fresh diesel, spins over good but no start ?

Fuel stop solenoid ? or Glow plug problem ?

 

[Spanner]

Was it running at all before changing the filter & fuel?

Did you bleed the fuel system after changing filter & fuel?

When cranking the engine over do you see any white smoke exiting the exhaust?

Can you test (Do you know how to test) power to the GP's with a Multi-meter or Test lamp?

Wasnt running before , it would spin over and belch black smoke, I can test the glow plugs when i get home from work, if there ok should i crack the injector lines and spin it over until it burps fuel ?
No white smoke .

Thanks Spanner

 

[Spanner]

Yes test GP's.
Black smoke kind-of implies fuel solenoid is allowing fuel through but it wouldn't hurt to bleed the injection pipes anyway.

Can you apply a jumper battery to enhance the cranking speed also?

I was thinking fuel solenoid , seems they had a problem with in the past ?
Will do the burp test on injector lines tomorrow . Fluke meter read good on glow plugs.
i can hear the solenoid click for a second when key is turned on ?
I'm an old fart , this is my first tractor , but the little diesel looks simple , I restore old cars on off time , gas motors are a breeze to me , probably overcomplicating it ?

Thanks Spanner

Mitsubishi built machines don't require bleeding air from the lines.

Just read that in the owners manual , some type of self purge system on these little Mitsubishi engines.

I'll look at it again tomorrow , hanging sheetrock today from Hurricane Harvey damage .

I'm leaning towards fuel solenoid , will pull and test it .

Thanks Pilgrim

Electric lift pump? Self-bleeding to the IP. ?

If you're getting 'black' smoke surely that's burnt fuel? White smoke is unburnt fuel, Either way it's fuel. So why do you suspect the solenoid?

 

[MadMax24]

sorry about the late response , working nights now .

The only thing left in the fuel system is fuel stop solenoid and a small gold colored canister I assume to be a purge canister ?
My thinking was the stop solenoid opens wide open for start then cuts back half way to run position ? messed with it a little bit yesterday between mowing grass and hanging sheetrock , would puff a little white smoke and the fuel solenoid would get hot to the touch , Am I all wrong here ?

 

[Spanner]

No, You're on the right track I think. Hot is not good.
You have Glow-Plugs so your solenoid is just Open/Closed. 1/0. On/Off. Run/Stop.
You may have either 2 or 3 wire connection. If 3, one is an earth/ground. The other two - There are two coils inside: High current for 'Pull' to pull it Open. Low current for 'Hold' to hold it open after it has Pulled against the 'Close' spring.
I don't know about gold canisters.

i'll shoot you a pic of the canister this weekend, these dogwatches wear me out .
I think its the purge canister because its tee'd into the vapor return line from fuel filter housing back to the fuel tank ?
It's got two wires on it , will throw the fluke on it this weekend , all the fuses are good in entire fuse block and both 50 amp fuses test good.
Fuel solenoid has a white and blue wire with 11.2 volts at terminal.

Fuel routing is from tank -filter-thru canister-to pump - to injectors .
Glow plug is bus or rail type with one hot wire on end, tested 11.5 volts at each glow plug terminal.
Holler at you this weekend on my days off .

Thanks Spanner

 

[Spanner]

Hmmm. How many volts directly across your battery terminals?

Which wire of fuel solenoid has the 11.2v and when? (Key Off/On/Start/?)

We know your GP's have a single wire but where does it come from (double checking here) and when does the 11.5v appear ( key same as above ) ??

 

[MadMax24]

Finally got a day off
If you need a good laugh read this , turns out the gold canister is the booster pump to prime the main fuel pump , cracked the injector lines , no fuel, cracked the main fuel pump outlet lines, no fuel , booster pump discharge line ,no fuel , got fuel to booster and booster sounds like its working on tractor and bench but will not pump, lines to it is not clogged , dealer wants $140 ordered one on ebay for $8.99 seems there a popular item ?
did I tell you this is my first diesel ?

Thanks Spanner

Snail mail dropped off the ebay pump last night ,took about 5 minutes to hook up , Tractor runs great
Dealer wanted $149 for pump , the ebay pumps are $8 bucks each , same pump , also for info ,Jegs sells a better pump for $23 under Autobest name brand for $23 , hope this helps someone in future ?
Thanks Spanner and every one that chimed in

I have a Max24 with a different 'failure to start' issue. I used it 2 days ago, with no issues. Today, the starter will not engage. Good power to all other systems, lights, turn signals and glow plugs. I checked the fuse block and found no fuses blown. I thought possibly it might be an out of adjustment clutch linkage so I tightened the linkage about 2 full turns but, still nothing. I checked the seat safety switch which seems to be working. I even jumped them out to make sure and still no power to the starter. I'm stumped.

UPDATE:
I found a youtube video that showed not only the 2 safety switches that I was aware of but, 3 others. It is here:

It was quite informative.
Lo and behold, apparently, I bumped one of the PTO levers when dismounting........ after checking them, boom, ignition.....
Live and learn........
