I'm getting fuel out the return line on ihection pump but not to the injectors
Expert:  Reggie Whiddon replied 12 months ago.

have you tried cracking the line at the injectors while starting

Expert:  Reggie Whiddon replied 12 months ago.

something else i do alot is i will take a rag and soak it in gas put it over the inlet to the air box hold it steady while someone cranks the engine it will start and run off the gas rag and hopefully bleed your air out

Ok yea like I said I have fuel out the return line on injection pump just not getting it to my injectors I'm going to try the rag I even tried wd40 it's the old 6.2 no turbo
Expert:  Reggie Whiddon replied 12 months ago.

i guarantee you the gas rag will crank it if you hold it it will run for a bit keep doing that it will bleed out. You are sure you have the correct fuel filter and of a good quality installed
