I have a Case 110 - 2009 which has had a reconditioned fuel pump fitted, it started but when it was run out on the road within a mile it started coughing and spluttering and lost power. It just made it back to the workshop and now it won't start. The reason for the reconditioned pump being fitted was because the tractor had done exactly the same the previous week. The diesel / tank / filters / hoses etc have all been checked. Any ideas please?
