Truck was running all of the sudden stop and not start again check fuel pump and it works. check ignition coil and have no spark. also, injectors are not staying check all the fuses and relays they all good check connections and they all good. do you guys think it may be the ECM?

My thought is either the ignition module or pickup coil has a problem. With bypass ignition, the ignition module controls spark during cranking, but, the ignition module has to have signal from pickup coil in distributor. If the computer does not see rpm signal, no fuel injector pulse.
