Test that the temperature sending unit in the water system is working properly. When the engine is cold, the computer puts it in cold start mode. Once warmed the temp sensor tells the computer to stop sending excess fuel to the engine and taking the cold start mode to off position.

that gray wire is the fuel pump power supply . You cut the wire were an positive tested it ??? An what does that mean . you positive tested it ? Wish you people would learn to talk like a mechanic would ! If you cut the wire near the relay an checked with a ohm meter or a test light with B+ volt , of couse it going to show ground ! It's going through the fuel pump windings to ground on the other side . What fuse keeps blowing ?ECM B - 20 amp ? This powers the fuel pump as well . May not even be the fuel pump circuit blowing the fuse . You need to find everything that fuse powers and isolate the different circuits . Videos on youtube showing how to find a short .

I believe the tail shafts are different and can't be interchanged.

Does the engine have spark to the spark plugs? Is there 12 volts to the coil and is the coil being triggered on the ground side? Check to see if the coil is sending spark to the distributor. Several more things to check that will not let the truck start. Check these and get back with me and I will help you more if needed. Good luck.
