So I have been having this problem with my 1992 F 250 idi for some time now. It starts rough when its cold or when it hasn't been run for a while (glow plugs are bad) but after its been warmed up and even on hot days, if I let it sit for more than 10 minutes or so, it takes a while to start. Now I know that there is no way a glow plug issue would be causing this problem because the outside tempreture is about 90 degrees and the engine has just begun to cool off from operating tempreture. That's why I'm thinking its a lift pump issue. There is no fuel leaking from the return lines or filter and the ip seems to be fine because when its running it has plenty of power and no smoke. has anyone else had this issue?
