99 7.3 DEAD

Was running great with 0 problems. Drove it home, parked it, came back about 2 hrs later and it started but was missing badly. I killed and tried to restart and it hasn't started since. Changed fuel filter and it seems to have good pressure to the fuel filter but still doesn't even try to start. Started and ran fine on small dose of ether. I have a hypertech tuner and it doesn't show any codes. Any ideas?

Pull the chip first.
DON"T ether it
It seems to have pressure or it does? What is the PSI?
So with ether it actually caught, and ran and idled on it's own?

Haven't checked the pressure but after trying to start the filter lid has alot of pressure on it. After ether it ran for a couple of seconds then died, but wasn't missing.

Ok so it only ran on whatever ether was in the system. That means you either have a lack of high pressure oil, fuel, or the injectors aren't being electronically actuated to fire.

Yea, you can watch for the oil pressure "gauge" to move after a while, and I think the tachometer should move on your truck while cranking too.
Also, does your WaitToStart light come on with KeyOnEngineOff?

Oil pressure comes up to middle while cranking, wait to start operates as normal, tach comes up a little. Engine smokes when turning over. No scan tool except my hypertech until tomorrow.

Unplug the icp sensor and see if it will start. Plug the block heater in see if that helps also.
