Looks like you need to shed the air in the injectors & lines.
To prime the system,
Charge the batteries, you're gonna be calling on them.
Be sure the fuel filter canister is full of fuel.
Disconnect the battery charger...very important.
Turn the keyswitch just enough to "bump" the starter to get The Free 25 Second Lift Pump Run.
Your lift pump pressure gauge should show 10 psi or greater.
Loosen the fittings on #1, #3 & #4 injectors with a 3/4" open end wrench.
Crank the engine for 10 seconds then check and tighten any wet, dripping fuel injector fittings.
Repeat the 10 second cranks & tighten the wet injector fittings until the engine kicks, trying to start then
tighten the remaining loose fittings and start the engine.
