I just finished my swap. Went from an 88 7.3 to a 87 6.9. I'm trying to start it for the first time. Ive got an electric fuel pump bypassing the lift pump. Ive got fuel in my fuel filter. Ive removed the injector lines and I don't get fuel spraying when I crank. Can anyone give me some help when it comes to bleeding the lines? Also ive been reading about the fuel shutoff solenoid? Any help or a bleed procedure would be greatly appreciated
What is the status of the IP on the 6.9 currently in the truck? Is it new, rebuilt? Or was it on the engine when you put it in the truck and you assume it's good? If the FSS does not make an audible click when you apply power, then it's not doing well. You can test it with just a length of wire from the battery positive to the FSS, without cranking the engine.
Personal preference, I'd have the fuel hard lines mounted on the injectors, but loose. I'm not sure it really makes a difference.
Be very careful cranking the engine. It takes a lot of power to turn one of these engines over due to the high compression. That starter motor is working hard. Crank for 15-20 seconds only. Then let it rest, cool off. If you overheat the starter motor you'll burn it out and have to replace it. Crank for 15-20 seconds, let it rest a couple minutes.
Even assuming the IP is working well, you'll have to crank for a while. These engines don't really push that much fuel at idle.
