Hi, first time posting. My 98 K1500 cranks but won't start. I replaced fuel pump and tank because it was full of sludge and crud. Had it running this morning, turned it off and now it won't start. I have 60lbs fuel pressure holding steadywith key on and off. Checked every connection I can find. Spark seems good at the plugs. Swapped spider injectors with another I had available. I thought trash may have plugged it up. Flushed fuel lines. New plugs, wires, rotor & cap. What am I missing?

update. It seems to actually be flooding. After pulling #2 & #4 plugs and aping it over I got it to crank up and run. This is the only way it will start. Pull a plug or 2, spin it, reinstall and crank with WOT.
