All of my glow plugs except one were reading .9-1.0 ohms with 12.6v current at the glow plug post. I replaced the one faulty glow plug. my dash glow plug light is cycling properly. I have a massive battery and have been cranking in 15-20 second interval's 4-5 times with a minute or so in between. It sputters and sends diesel smelling exhaust out the rear. I changed the main fuel filter and have plenty of fuel feeding the supply line of the IP. I cracked the injectors again and I am getting fuel and bubbles out of all of the injectors except the first one from the radiator, which I guess is actually the last one since it has a return line back to the main filter housing. Is there something inside the IP that controls fuel flow that I may have accidently bumped or changed?

I will take the vaccum line off of the shutoff and see if anything changes. Thank You!
