Engines / HR3 engine problems
« on: May 20, 2022, 01:22:05 AM »
Well guys I’m needing some help I have a 3 cylinder hr3 that will run when the motor is cold and then die when it warms up. Wait about a minute and it will start run for a few seconds then die. I would understand if one or two cylinders not running if it was a single fuel pump but that isn’t the case. The fuel pump is new and I took it apart to check if there is a clog but it’s clean and pumps good. I’m at a loss here. What else would cause it to act that way?
