I have an 03 6.0 and I just changed the oil and now it cranks but no start. My resources are limited to check numbers but I have a scan gauge ii. I live in rural nowhere Montana and had to use a napa gold filter. Ran fine before oil change. 15 quarts of 10w-30. I even put the old motor craft filter back in and still no start. The filter cap is motor craft I only got the cartridge napa part. I really need it to run tomorrow for work and I'm now up s*it creek without a paddle. The valves inside the filter housing seem to be ok. Any help is useful. I know I didn't use the "right parts" but it's all I could get out here without ordering it and I'm im a bind for time.
