I just finished installing M&H timiing spacer and injectors. WHats the best way to bleed the fuel system?

Crack the fuel line/s going in to the injector/s. Turn the engine over 'til fuel comes spurting out in a solid stream. It would be a good idea to disable the engine somehow so it won't fire up. Normally I'd pull the cam position sensor, but that's a little hard on our trucks!
That's the easiest way, but you could also pump fuel through with the hand primer... I wouldn't recommend this however as it's a genuine pain.

If you pull the wire off the shutdown selonoid it won't start. All I did when I did my injectors was crack the lines loose on 1,2 and 3 and crank it till I saw a good bit of fuel. Then I tightened those and cracked loose 4,5 and 6 and cranked till I saw fuel and tightened them and she started right up.

Having the fuel shut-off solenoid closed won't allow fuel flow to the injectors for the purpose of burping the air.

Just loosen the first two or three injector feed lines and crank the engine over till fuel squirts and tighten them back up.

It still may stumble a bit to begin with, but it'll clear up.

Another advantage of an electric FP back near the tank; you can bleed the system up to the IP without spinning the engine. That covers all the fuel filter and LP replacement bleed needs.

I am sorry I wasn't thinking about the fss not allowing fuel to the injectors I am a little slow today lol.

That auxilliary electric-pump I have in a by-pass line proves quite handy for such occasions.

I would never trust an electric-pump as my only delivery-pump, but they do have their advantages, such as being able to pump when the engine is OFF.
