88 f350 7.3 IDI starting problem

have an 88 f350 7.3 idi that is a bear to start usually won't start without a tiny squirt of ether then it'll fire right up no problem....after that it'll start all day long until you let it sit for an extended period. was gone through by a diesel mechanic injector pump, hoses, injectors checked and replaced, o rings, new plugs. Still won't start without that small ether shot any ideas what else it could be almost seems like its still possibly losing prime from sitting.

Sounds to me like compression issues. Ether is like crack for diesels, once they have it... They must have it. Your rings are worn from the ether use that its a must every time the engine gets cold. The only way to fix it is to basically take the engine apart and "rebuild" it. Ether is a big no no.

ended up being engine losing prime after it sits. Once it has fuel can hit glow plug for 15 seconds and it'll start up after a couple of cranks. Just have to figure out where the leak is allowing all the fuel to go back into the tank. didn't help that the little shots of ether obvious burned out the old glow plugs...got new set in there might just put a little electric primer pump in it get it....run it to prime the system then crank her over and go we'll see.
