Trouble starting diesel

tree cutter 08 · Jun 26, 2017

Got a 98 new Holland skidsteer. Was running fine last October. Tried to crank it earlier in the spring and it only hit a time or to and that was it. Since then I've replaced fuel, both filters and glowplugs. Fuel system is has been bled and return hose is working. Glowplugs are working also. While cranking it will not smoke any out the exhaust, but will slightly when you give it a shot of either but still won't hit. What's the chance all injectors are plugged? I've about give up and ready to send it to the shop. Any ideas?

If either won't get it cranking I would say fuel pump. Check the relays first though.

how are you putting the ether to it? If it won't hit on ether, then something is outta time, or no compression.

Right off, I would say that you aren't getting the ether into the combustion chamber.

Pump is working, I've sprayed into the intake with filter removed. Usually have to give it a shot in cold weather. I've wandered about the compression but it was running fine when parked. Does have around 3 k hours though.

How long has the fuel been in it? Checked the fuel and filters? I'm waaay out of my league here offering advice, but back in the day when I used to race sailboats, we often didn't use the diesel engine (otherwise known as the D-Sail) enough to prevent algae from growing in the tanks and clogging the whole works.

had a dozer that had the same problem. there is a glass ball in the fuel line between the tank and pump to keep it from back draining. found the ball (bout a number 4 buckshot) removed it and ran fine from then on.

Does it have the push button primer? If so i would say it's the diaphragm in that primer.
It does have fuel correct? :banginghe

just to repeat myself.....

if you put the ether in it, and it won't hit, it is either out of time, or no compression. period, end of story.

Get someone to turn the engine over and keep spinning that sucker. While they are turning it over, start spraying ether straight down the intake with the air filter removed. Keep spraying until it either hits, starts to knock or it becomes obvious it isn't going to crank.

Well pappy you are right. Low on compression. Shop is going to pulled the head and check the rings and cylinders and possibly rebuild the head, or find a new engine.

Back up and running. Complete head rebuild. Also new injectors and water pump. Thanks for the help and advice.
