How do you reset engine stop.Iam not getting any fuel to the injectors. I have a CK20 ,purchased in 2006 .Engine stop botton does not move.It is all the way in and lever does not move on manual connection attached to injection pump. Fuel filter pluged and engine quit,replaced filter and there is fuel being pumped to IP but no fuel to injectors.Engine shut off was pulled by error and then pushed back in.It does not come back out. I am at a lost as what to do,any help would be welcome. Thank You
