Won't start even using starting fluid

[gunnison]

Without going into the whole history of what is going on. Can anyone tell me possible reasons my truck won't start even when using ether? I took off a valve cover and the valves are moving, so I don't think its a timing gear issue. There is fuel going to the fuel bowl. I just replaced the CPS, electric fuel pump, fuel filter, IPR, oil and oil filter change. All help appreciated. I have not run compression checks yet.

Check for codes....

Does the WTS light come on?

Does the tach move while you're cranking it?

Any white smoke from the exhaust?

Wait... you converted to e-fuel, and still have an original fuel bowl?

Just checked your profile. If it's your '99 truck, then try posting in the SuperDuty ('99-'03) forums. Fuel systems between OBS and SD are vastly different.

Might be PCM

Here's an update. 1st of all, sorry about posting this in the wrong "era" of truck. Mine's a 1999. Anyway, It looks like I only have about half the recommended cylinder compression. After adding some oil to each cylinder through the glow plug hole it helped raise the compression. I believe this lack of compression is called "washed down". I believe the can of Engine Restore did this. I used it hoping to decrease the blow by. After reading this stuff is bad for powerstrokes, specifically the injectors and/or IPR; I changed the oil twice. But the effects were already there. So far, it seems the injectors and IPR are "ok". But a hard lesson was learned. I've used Engine Restore in the past on gas engines and had amazing results. But not this time. Thanks for all who replied with ideas, etc.
