Bob, an alarm system, what all do you monitor? The previous owner of my machine ran a tree branch up thru the oil filter, not watching oil pressure gauge ruined engine.

I monitor coolant temperature, oil pressure, and fuel pressure using mechanical Murphy ©Switchgages. The set points and contacts are easily adjusted through the gauge face. These are industrial quality gauges and priced accordingly.

Surely he knew these machines don't have a belly pan. He didn't know the machine or it's limitations, and wasn't operating it accordingly.The previous owner of my machine ran a tree branch up thru the oil filter, not watching oil pressure gauge ruined engine.

A big 10-4 on your previous thread. My machine since it died abruptly out in the boon docks now is very difficult to get started when its cold. Previously it started very easy even when quite cold. I have been bleeding the fuel system when I get it started to no avail. Is this a clue of what might have given me these headaches?

Do you get any smoke from the exhaust now when trying to start? Does your fuel injection pump oil now smell like diesel fuel? Have you tried using the glow plugs before you start? Once bled, the fuel system should not require further bleeding.
One other thing, did you replace the spin-on secondary fuel filter?

I have noticed that I seem to be getting more white smoke out of exhaust when cranking to start. I won't be able to smell the fuel injection pump oil as I have to be away from the machine for about a week. But on that subject, I checked the oil level on the pump, never saw anything in the owners manual about oil level in an injection pump, saw it on a post somewhere on this site, it was low, added oil to what I believe was the correct overflow plug, next time I got it started I had oil coming out of another overflow.?? I have been using the glow plugs for about 12 seconds. I changed spin on filter, and made sure I bled air that might have been introduced. Is the white smoke significant? Thanx Bob

Also make sure the fuel tank breathes, you need air to replace the fuel that is drawn from the tank.
Removing the filler cap is one easy test.
Every fuel tank has a screen just before the outlet.
Crud can block that screen and starve the engine.
Also the slightest leak in the injector inlet line can allow air and the injector pump can't suck air, only fuel.

White exhaust smoke in the absence of any coolant loss indicates unburned fuel, so if it was determined that you had diesel bugs that were undetected for some time, one or more of your injectors could be dribbling. These injectors are cheaper to replace than rebuild, but nominally cheaper yet to get pop tested if you have a diesel shop nearby.
There are specific resistance readings for glow plugs but for brevity your ammeter should show close to a full discharge when you have the glow plugs applied, anything less indicates failed or failing glow plugs. You may also have inadvertently knocked a glow plug wire loose while working on the engine.
