Just as title says. Has the PIDD gauge and has no codes. Started the sled in the trailer after sitting for 2 months. Put it in reverse, it barley made it out of the trailer then died. Now it won't Rev past 2300 RPM. Track off ground. Plugs are oily changed them no difference. Seems like it's not getting fuel. Filter, pump, injector? Figured it would have gave me a fault code for those. Seems to idle fine, lots of oil out exhaust. Anyone have any suggestions? Thanks! Relays where just changed not because they where acting up just preventing.
