re new holland lx665 turbo skid steer i have a 1997 new holland skid steer, it has a problem starting, ill explain, when it is cold, lets room temp, it will only start , with , the throttle wide open , and takes , a great deal, of cranking , and is smoking alot , and when it starts , it runs only at high speed if u idle it, it will die, but if u run it at half throttle , for a few minutes , then it will idle, once its warmed , up it will start, up fine , but let it sit over night, and its the same , hard to start again, if u plug in the block heater, for a couple of hours, it starts , right away, at idle, there is no lack of power, no oil consumption, no excessive exhaust , smoke, i have changed the fuel pump, new filters, new injectors, new glow plugs, compression , test 350 per cylinder, also note , when i put new glow , plugs in , it starts very quickly, but the glow plugs , burn out after a couple of uses, and checked , they r 12volt glow plugs, and thats , all that that there r getting , is 12 volts, the real stumper , is how it starts , so nicely, when the block heater is plugged in, but should , not have to , in the summer months, could really use some advise
