2000 GMC T7500 w/cat engine as previous question asked, Ran ok -let it sat for 8 hrs and would not start!!! Engine cranks normal speed,removed hose @ intake and sprayed starting fluid and it will start. Did it 3 times,then kept it running for 15 seconds by spraying s. fluid. In the last month it had a problem2 times no start,sprayed s. fluid and it started and kept running. It was diagnos with a bad injector over 1 year ago. Has a dead misson at leased1 cyl. It overheated , I'm not sure how hot it got, but doesnt loose to speak of coolant. it has run at least 1 gallon low on oil. Major oil leaks. On inner timing timiing cover their 2 sensors in front of pump whick are oil soaked with fresh oil...Not clear on some of my statements because its my neighbors truck.!!!
