Hey guys, new here. My 4 co-workers and i man the garage for a small family owned quarry op. We work on all types of stuff, bosses lawn mower, Mack dumps, catapillar end dumps, rock drill, forklifts ect. Our recent head scratcher is a Volvo 220 E wheel loader with electronic controlled centrally mounted injectors, has new injector sleeves, new feed pump, new primary filter base with primer. this machine will not start without ether or some other fuel already in the combustion chamber at time of crank. After changing injector sleeves machine fired right up but only because of the fuel lost into the combustion chamber when removing the old ones. When we shut the machine off and tried to crank it over just 5-10 seconds later it again wouldnt start. This is making me lean towards an electrical issue. No smoke while cranking so im assuming no fuel while cranking even though the injectors are getting fuel and power. The only fault code is for a broken coolant level sensor, can anyone confirm that this is or is not causing my no start condition? If so why can it be over ridden with a shot of ether? and if not what could be causing my injectors not to open at a crank but run perfectly fine once a quick shot of ether or raw fuel is in the combustion chamber at crank? thanks in advance- Brad
