Just cranking the engine should after a couple tries prime the system.

But, if you want to prime it without running here is what you can do.

If you jumper with a Fused 16 amp jumper wire with alligator clips from

fuse 5 to fuse 7 this will make the fuel pumps run without the key on.

after only about 10 to 20 seconds this will fill the whole fuel system

and it will be at full operating pressure. If it doesn't start then you

may have something else bad. If your fuel pump relay doesn't get power

from fuse 13 and/or its not getting ignition pulses from the coil term

one then the relay won't turn on the fuel pumps.
