Fresh rebuilt 7.3 no start

So I tore the engine down completely rebuilt it, and sent the tranny out to get build. I switched to e-fuel, got rid of the fuel bowl and put a stage 2 colt cam in it. Well tonight I tried starting it without the tranny in and it wouldn't turn over with the key but it would if you jumped the solenoid on the passenger fender. Cranked on and off for about 20 minutes and it wouldn't fire. I filled the hpop reservoir beforehand and after cranking it went down and I filled it again and tried again but still wouldn't fire. I have 70 psi of fuel pressure. The injectors were all in good shape and re o-ringed. The truck ran and started great before rebuild. Is there possibly a safety switch on the tranny keeping it from firing, or is there something that was connected to the fuel bowl that needs to be connected or something? I didnt check for any sort of power going to the injectors yet that will be tomorrow but Any other help or a place to start would be appreciated.

Re: Fresh rebuilt 7.3 no start

After rebuilding a engine there is going to be no oil in the oil rails to fire the injectors and it is going to take a lot and I mean a lot of cranking to get it there. The safety switch will only keep the starter from engaging.

Have you tried cranking with the valve covers off to see if there is any oil squirting out of the injectors? You also might want to check all the fuses if you haven't already. Mainly the #22 and #9 under the hood.
