Looking for some help here.
I have an old international 4186 and the other day I fired her up to clear the yard made it to the house. Left it idling as I went in to grab a coffee. When I came out it was running rough then died before I could get back to it.
It turns over fine.
Have fuel right at the injectors
Filters are new
She won’t even fire with some ether help

Any help is greatly appreciated
Thanks

That sounds like something electrical, connection wise, rattled loose.

Still toast

Check d over what little electrical is on the old girl all good
New air filter
New fuel filters. Got fuel to injectors
New batteries
Valves all move when rolling it over
What else could I have missed

Is the inj. pump an Ambac or American Bosch mdl 100??
The lines come off the top of the pump in a circle & has a hand primer on the back..
Its possible for that pump to pump fuel TO the injectors but not have fuel enough to open them..
If it were mine, I'd pull an injector OUT & hang it outside the engine & SEE if its firing..
DO NOT be ANYWHERE NEAR THE SPRAY if its working.. OR have an OPEN FLAME..
Let me know what type of fuel system is on it & we can go from there..
